28003715 Installation / wiring

Wiring type and cross section
For wiring use stranded wire with ferrules or solid wire from 0.2–1.5 mm².
Strip 8.5–9.5 mm of insulation from the cables to ensure perfect operation of
the push-wire terminals.
Use one wire for each terminal connector only.

Loose wiring

Press down the “push button” and remove the cable from front.

Fixing conditions when using as independent Driver with Clip-On

Dry, acidfree, oilfree, fatfree. It is not allowed to exceed the maximum ambient temperature (ta) stated on the device. Minimum distances stated below are recommendations and depend on the actual luminaire. Is not suitable for fixing in corner.

Device not suitable for covering with thermally insulating material according to IEC 60598-1 Ed.9

Wiring guidelines

• The cables should be run separately from the mains connections and mains cables to ensure good EMC conditions.
• The LED wiring should be kept as short as possible to ensure good EMC. The max. secondary cable length is 2 m (4 m circuit), this applies for LED output.
• To comply with the EMC regulations run the secondary wires (LED module) in parallel.
• Secondary switching is not permitted.
• The LED driver has no inverse-polarity protection on the secondary side.

Wrong polarity can damage LED modules with no inverse-polarity protection.
• Wrong wiring of the 28003715 can lead to malfunction or irreparable damage.
• To avoid damage of the 28003715 , the wiring must be protected against short circuits to earth (sharp edged metal parts, metal cable clips, louver, etc.).

Replace LED module

1. Mains off
2. Remove LED module
3. Wait for 30 seconds
4. Connect LED module again
Hot plug-in or secondary switching of LEDs is not permitted and may cause a very high current to the LEDs.

Installation note

Max. torque at the clamping screw: 0.5 Nm / M4

Software / Programming / Interfaces

Software / programming

With appropriate software and interface different functions can be activated and various parameters can be configured in the 28003715 .
The 28003715 supports the following software and interfaces:
Software / hardware for configuration:
• companionSUITE (deviceGENERATOR, deviceCONFIGURATOR, deviceANALYSER)
Interfaces for data transfer:
• NFC
• Control input switchDIM

Nearfield communication (NFC)

The NFC Interface allows wireless communication with the 28003715. This interface offers the option to write configuration and to read configuration, errors and events with the companionSUITE.

A correct communication between the LED driver and the NFC antenna can only be guaranteed if the antenna is placed directly on the 28003715. Any material placed between the 28003715 and the NFC antenna can cause a deterioration of the communication quality.

After programming the device via NFC power up the device one time for one second till the deviceANALYSER can read out the parameters. With a strong NFC antenna, several products can be programmed simultaneously (“multi device programming”).

We recommend the use of following NFC antenna: www.tridonic.com/nfc-readers NFC is complied with ISO/IEC 15963 standard. Changing parameters via NFC shall be done by qualified engineers only.

Control Input switchDIM

A standard pushbutton can be wired on the terminals (switchDIM). Integrated switchDIM function allows a direct connection of a pushbutton for dimming and switching. Brief push (< 0.6 s) switches 28003715 ON and OFF. The dimm level is saved at power-down and restored at power-up.

When the pushbutton is held, LED modules are dimmed. After repush the LED modules are dimmed in the opposite direction. In installations with LED drivers with different dimming levels or opposite dimming directions (e.g. after a system extension), all 28003715 can be synchronized to 50 % dimming level by a 10 s push.

Use of pushbutton with indicator lamp is not permitted. The dimming behaviour is slightly different for mixed systems with DALI and bDW control gears.

Functions

OEM Identification

The OEM (Original Equipment Manufacturer) can set his own identification number. DALI Part 251: Memory bank 1 extension.

OEM GTIN

The Original Equipment Manufacturer (OEM) can set his own Global Trade Item Number (GTIN). DALI Part 251: Memory bank 1 extension.

Luminaire data

This function provides the asset management with accurate data about the luminaire. DALI Part 251: Memory bank 1 extension.

Label information

In production, an individual label can be printed out for each device. For this there are different default values (Batch No., Production Date, …) available. In addition, you can use these two text input fields to insert your own luminaire information and print it out.

LED current

The LED output current must be adapted to the connected LED module. The value is limited by the current range of the respective device.

Device operating mode

A Tridonic driver supports several control signals. These control signals are automatically detected and the mode is adapted. If only one special device mode is required, this mode can be fixed here. “Automatic detection” is the default setting.

Factory reset

This device supports the function to reset all parameters back to factory defaults.

switchDIM fading

Here you can set the fade time of the control gear when using switchDIM.

Constant Light Output (CLO)

With this function the light output of the LED module can be kept equal over the lifetime. The light output of an LED module reduces over the course of its lifetime. The Constant Light Output (CLO) function compensates for this natural decline by constantly increasing the output current of the 28003715 throughout its lifetime.

CLO shall be achieved by limitation of the LED current at the commissioning of the 28003715 and providing a linear interpolation of the current over the time, depending on the data points given by the user.

Light level in DC operation

In emergency light systems with a central battery supply the DC recognition function uses the input voltage to detect if emergency mode is present. The 28003715 then automatically switches to DC mode and dims the light to the defined DC level.

Without DC recognition different and more complex solutions would have to be applied in order to detect emergency mode. DC recognition is integrated in the device as standard.
No additional commissioning is necessary for activation. This is a safety-relevant parameter.

The setting is relevant for the dimensioning of the central battery system. The LED driver is designed to operate on DC voltage and pulsed DC voltage. For a reliable operation, make sure that also in DC emergency operation the 28003715 is run within the specified conditions as stated in chapter
“4.1 operating window”.

Light output level in DC operation: programmable 15 – 100 % (factory default = 15 %, EOFi = 0.13).

The voltage-dependent input current of Driver incl. LED module is depending on the used load.

The voltage-dependent no-load current of Driver (without or defect LED module) is for:
AC: < 18.3 mA
DC: < 2.4 mA

Enhanced power on level (ePOL)

The Enhanced Power On Level parameter defines the power level that is set automatically when power is restored after a power failure. The Enhanced Power On Level can be set to a fixed value (0 – 100 %) or can recall the memory value.

The memory value is the last value the 28003715 was set to before the power failure.

Scenes and groups

Each device can be a member of up to 16 groups. Also, 16 different scene values can be stored in each device.

Power-up fading

The power-up function offers the opportunity to modify the on behavior. The time for fading on can be adjusted in a range of 0.2 to 16 seconds. According to this value, the device dims from 0 % up to the power-on level. By factory default no fading time is set (= 0 seconds).

deviceKEY

With this function, individual device functions can be protected from unauthorized changes by a password.

Energy reporting

This function provides the information related to energy reporting accessible through memory banks in this driver. Several functions and values could be read out to gain access in Content
management systems.

Report and values for Active power, Active Energy and many more can be read out.

Protective features

Overtemperature protection

The 28003715 is protected against temporary thermal overheating. If the temperature limit is exceeded the output current of the LED module(s) is reduced. The temperature protection is activated above tc max.

The activation temperature differs depending on the LED load. On DC operation this function is deactivated to fulfill emergency requirements.

Short-circuit behaviour

In case of a short-circuit at the LED output the LED output is switched off. After restart of the 28003715 the output will be activated again. The restart can either be done via mains reset or via interface.

No-load operation

The 28003715 will not be damaged in no-load operation. The output will be deactivated and is therefore free of voltage.When connecting an LED load, restart the device to activate the LED output.

Overload protection

If the maximum load is exceeded by a defined internal limit, the 28003715 turns off the LED output. After restart of the LED driver the output will be activated again. The restart can either be done via mains reset or via interface.

Miscellaneous

Insulation and electric strength testing of luminaires

Electronic devices can be damaged by high voltage. This has to be considered during the routine testing of the luminaires in production.

According to IEC 60598-1 Annex Q (informative only!) or ENEC 303-Annex A, each luminaire should be submitted to an insulation test with 500V DC for 1 second. This test voltage should be connected between the interconnected phase and neutral terminals and the earth terminal. The insulation resistance must be at least 2MΩ.

As an alternative, IEC 60598-1 Annex Q describes a test of the electrical strength with 1500V AC (or 1.414 x 1500V DC). To avoid damage to the electronic devices this test must not be conducted.

The equipotential terminal is used to connect the heat sink and the 28003715 to reduce transients.

Conditions of storage and use

Humidity: 5 % up to max. 85 %, not condensed (max. 56 days/year at 85 %)

Storage temperature: -40 °C up to max. +80 °C

The devices have to be acclimatised to the specified temperature range (ta) before they can be operated. The 28003715 is declared as inbuilt LED controlgear, meaning it is intended
to be used within a luminaire enclosure.

If the product is used outside a luminaire, the installation must provide suitable protection for people and environment (e.g. in illuminated ceilings).

Placement

basicDIM Wireless has an integrated antenna for easy integration. In order to maximize the range in every direction some design guidelines should be
taken into consideration when mounting the device.

The antenna is located on the corner of the enclosure. It is on the top side of the internal PCB (Printed Circuit Board).

When the device is mounted on a metal plate (e.g. frame of a luminaire), it may efficiently block the radio frequency signal. In this case, a cut-out underneath the antenna may be needed for the RF signal to exit the structure. The cut-out area should be as large as possible. Also the device should be placed as far away from any vertical metal structures as possible.

The range of the communication signal is depending on the environment e.g. luminaire, construction of the building, furnitures or humans and needs to be tested and approved in the installation.

The range of the 28003715 is up to 15 m (from unit to unit and from unit to App). If the 28003715 are installed in a extremely well-shielded luminaire (metal body, spotlight, …), then the range is up to 5 m.

This information is given as a guide. Luminaire construction, installation situation and construction conditions have a direct influence onthe communication range and must be tested by the customer.

Network compatibility

This Driver is fully compatible with networks which support up to 250 nodes (Evolution networks). If the Driver is used with different types of basicDIM Wireless devices in an Evolution network, their compatibility has to be checked before. If a device is not compatible with Evolution networks,

it can be only used in networks which support up to max. of 127 devices (Classic networks).

Maximum number of switching cycles

All LED driver are tested with 50,000 switching cycles. The actually achieved number of switching cycles is significantly higher.

Constant Current Casambi LED drivers pair intelligent Casambi Bluetooth wireless control with drivers that supply a fixed electrical current (usually measured in mA). They are primarily designed to power high-performance LED luminaires (such as spotlights and downlights) in smart homes, retail spaces, and offices.

Why Choose Constant Current Casambi Drivers?

Smart Wireless Control: They form a self-organising Bluetooth mesh network, allowing you to group fixtures, set timers, create scenes, and dim lights from your smartphone or tablet—no external gateways required.

Ultra-Deep Dimming: They utilise constant current reduction or PWM dimming to provide smooth, flicker-free dimming (often down to 0.01%).

Tunable White Support: Many models feature dual or multiple channels, making them ideal for adjusting colour temperature (CCT).

Common Technical Features

Configurable Output: Instead of buying multiple drivers, many models use DIP switches or NFC programming so you can precisely adjust the exact output current (e.g., 350mA to 1400mA) to perfectly match your specific LEDs.

Wide Voltage Range: They operate on standard 220-240V AC mains input and output variable DC voltages.

Built-In Safety: They typically feature built-in protections against over-heating, short circuits, and over-loads.
