Glow wire test

according to EN 61347-1 with increased temperature of 850 °C passed.

Thermal details and lifetime

The LED control gear is designed for a lifetime stated above under reference conditions and with a failure probability of less than 10 %.
The relation of tc to ta temperature depends also on the luminaire design.
If the measured tc temperature is approx. 5 K below tc max., ta temperature should be checked and eventually critical components (e.g. ELCAP) measured. Detailed information on request.

Circuit diagram

87501050 Mains supply wiring

For wiring use stranded wire with ferrules or solid wire from 0.5 – 1.5 mm².
For perfect function of the push-wire terminals (WAGO 250) the strip length should be 8.5 – 9.5 mm.

Release of the 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.

87501050 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 typical secondary cable length is 2 m (4 m circuit).
• To comply with the EMC regulations run the secondary wires (LED module) in parallel.
• 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 damage of the Driver, the wiring must be protected against short circuits to earth (sharp edged metal parts, metal cable clips, louver, etc.)

87501050 Functions

Overload protection

If the maximum load is exceeded by a defined internal limit, the LED will flicker, and output voltage will be reduced.
When fault is removed, the driver can go back to work automatically without resetting input main power.

Overtemperature protection

The LED driver is protected against temporary thermal overheating. If the temperature limit is exceeded the LED will flicker, and restart automatically after the driver cold down. The temperature protection is activated approx. + 15 °C above Tc max.

Short-circuit behaviour

In case of a short circuit at the LED output the LED output is switched off. When fault is removed, the driver can go back to work automatically without resetting input main power.

No-load operation

The LED driver will not be damaged in the no-load operation. When the output is floating and doesn‘t connect the LED modules, the output voltage will keep the max. voltage (< 25 V). After connecting the LED load, the driver works normally without resetting the main power.

Use of PWM dimmers

PWM dimmers can be used to dim the attached LED module.

87501050 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.

Conditions of use and storage

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 LED driver 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).

Maximum number of switching cycles

All LED driver are tested with 50,000 switching cycles.

Non-dimmable constant voltage LED drivers provide a steady, fixed 12V or 24V DC output from an AC source, designed for applications requiring consistent brightness without dimming capability. Ideal for LED strips, signage, and cabinet lighting, they ensure stable, flicker-free performance and long lifespans, commonly in 12W–200W+ capacities.

Key Features and Applications

Constant Voltage Output: Maintains a fixed voltage (typically 12V or 24V DC) regardless of the load, making them perfect for devices with built-in current limiting, such as LED tapes and fixtures.

Non-Dimmable Nature: These drivers are designed to be switched on or off only. They do not support external dimming controls (like TRIAC or 1-10V) and may flicker or fail if connected to one.

Typical Uses: Frequently used in retail displays, under-cabinet lighting, commercial signage, and, per YouTube, for powering complex systems like RGB or tunable white LED strips controlled via external controllers.

Reliability & Cost: Generally more cost-effective and reliable for setups that do not require ambiance adjustment.

Selection Factors

Voltage Matching: The driver’s output voltage must match the LED product (e.g., a 24V strip requires a 24V driver).

Wattage Load: The total power (wattage) of the LED load should not exceed the driver’s maximum rating. It is advisable to allow a 10-20% power buffer.

IP Rating: Select based on environment (e.g., IP20 for indoors, IP65+ for damp/outdoor locations)
