28000695 Wiring

28000695 Wiring type and cross section

The wiring can be in stranded wires with ferrules or solid with a cross section of 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.

28000695 Wiring guidelines

• Run the secondary lines separately from the mains connections and lines to achieve good EMC performance.
• The max. secondary cable length is 2 m (4 m circuit).
• For good EMC performance, keep the LED wiring as short as possible.
• 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 LED Driver can lead to malfunction or irreparable damage.
• To avoid the damage of the Driver, the wiring must be protected against short circuits to earth (sharp edged metal parts, metal cable clips, louver, etc.).

28000695 Earth connection

The earth connection is conducted as protection earth (PE). If the LED Driver will be earthed, protection earth (PE) has to be used. There is no earth connection required for the functionality of the LED Driver. Earth connection is recommended to improve following behaviour:

• Electromagnetic interferences (EMI)
• Transmission of mains transients to the LED output

In general it is recommended to earth the LED Driver if the LED module is mounted on earthed luminaire parts respectively heat sinks and thereby representing a high capacity against earth.

Interfaces / communication

Configuration input ready2mains (L, N)

The digital ready2mains protocol is modulated onto the mains signal which is wired to the mains terminal (L and N).

Function: adjustable current

The output current of the LED Driver can be adjusted in a certain range.

For adjustment there are two options available.

28000695 Functions

Function: adjustable current

Option 1: I-SELECT 2

By inserting a suitable resistor or third party resistor into the I-SELECT 2 interface, the current value can be adjusted. The relationship between output current and resistor value can be found in the chapter
“Accessories I-SELECT 2 Plugs”

Please note that the resistor values for I-SELECT 2 are not compatible with I-SELECT (generation 1). Installation of an incorrect resistor may cause irreparable damage to the LED module(s)

Resistors for the main output current values can be ordered from Tridonic (see accessories).

Option 2: ready2mains

Adjustment is done by the ready2mains Programmer and the corresponding configuration software (see ready2mains documentation).

Current adjustment can only be done five times over ready2mains. To program the LED Driver a connected load is necessary that is within the operating window of the LED Driver.

The priority for current adjustment methods is I-SELECT 2 followed by ready2mains (lowest priority).

ready2mains – configuration

The ready2mains interface enables the configuration of the mostly used parameters via the mains wiring.

In the case of EXC LED Driver, it is the LED output current as well as an optional lockbit to prevent any accidental configuration at a later stage.

The configuration is done via the ready2mains Programmer, either directly at the Programmer itself or via a respective software tool. For details on the configuration via ready2mains see the technical information of the Programmer and its tools.

Short-circuit behaviour

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

No-load operation

The LED Driver will not be damaged in no-load operation. The output will be deactivated and is therefore free of voltage. If a LED load is connected the device has to be restarted before the output will be activated again.

Overload protection

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

Overtemperature protection

The LED Driver 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.

DC emergency operation

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 LED Driver is run within the specified conditions as stated in chapter “4.1 Operating window”.

Light output level in DC operation (EOFi): 68 % (cannot be adjusted) 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: < 22 mA
DC: < 2 mA

Intelligent Voltage Guard

Intelligent Voltage Guard is the name of the electronic monitoring of the mains voltage. It immediately shows if the mains voltage rises above certain thresholds. Measures can then be taken quickly to prevent damage to the LED Driver.

• If the mains voltage rises above approx. 280 Vrms (voltage depends on the LED Driver type), the LED light starts flashing on and off.
• To avoid a damage of the LED Driver the mains supply has to be switched off at this signal.

Constant current (CC) LED drivers are specialised power supplies that maintain a fixed, consistent current (measured in mA or A) to LED lighting systems, varying the voltage to prevent premature failure, flickering, and thermal runaway. They are ideal for high-power LEDs, downlights, and series-wired arrays, ensuring uniform brightness.

Key Aspects of Constant Current LED Drivers:

Functionality: Unlike constant voltage (CV) drivers, CC drivers adjust the output voltage within a specific range to keep the current stable, regardless of changes in the LED’s electrical properties due to heat.

Wiring Configuration: These drivers require LEDs to be connected in series (daisy-chain), where the positive wire of one LED connects to the negative of the next.

Applications: Primarily used for high-output fixtures, downlights, retail, and museum lighting where precise illumination and long life are critical.

Specifications: Commonly rated for 350mA, 700mA, or 1A. They are often rated with a DC voltage range (e.g., 6-12VDC) and a fixed current (e.g., 700mA).

Dimming: Dimmable models are available, supporting protocols like 0-10V, DALI, and TRIAC.

Benefits: Prevents over-driving LEDs, which reduces heat, extends lifespan, and ensures consistent light output.
