Product Usage Instructions

To use the Constant current built-in driver BML-B Series, please follow these instructions:

1. Ensure that the light you are using is compatible with built-in drivers.
2. Select the appropriate model based on your required output parameters.
3. Connect the driver to the light’s output wire using circular compact appearance design.
4. Make sure the driver is placed inside the light and adheres to SELV and Class II design standards.
5. Check if the driver has the necessary certifications (CE, ENEC, UKCA, RCM, EL).
6. The driver is suitable for indoor use with IP30 protection grade.
7. The nominal lifetime of the driver is up to 100,000 hours, and it comes with a 5-year guarantee.
8. If you require central emergency application, ensure that the driver supports 100% output in DC input.
9. The driver also provides protective features such as short-circuit and no-load protection.
10. For lights with external drivers, this driver is not suitable.

Expected life-time

BK-BML040-B
Life-time vs. case temperature

• The life-time of the LED driver (calculated based on the 90% survival rate).
• The relation of tc to ta temperature depends also on the luminaire design.

Surge

Remarks

• The number of drives mounted under different MCBs in the table is the maximum value. Please do not exceed this number during installation.
• Calculation uses typical values from ABB series S200 as a reference.
• Different brands and models of miniature circuit breakers, the number of drives mounted will be slightly different.
• If the ambient temperature of the MCB installation exceeds 30°C or multiple MCBs are installed side by side, the number of drives mounted will be reduced and the calculation needs to be recalculated.
• Electrician’s usually consider Type B for household lighting and Type C for commercial lighting application.

Functions

Output short-circuit behaviour

• Output short-circuit will not damage the driver.
• After removing the short-circuit fault point, the drive will automatically restore output.

Output no-load operation

• Output no-load will not damage the driver.
• Please turn off the power supply of the driver first if you need to connect the LED load.

Installation note

Hot plug-in

• Hot plug-in is not supported due to residual output voltage of > 0 V.

Wiring guidelines

• All connections must be kept as short as possible to ensure good EMI behaviour.
• Mains leads should be kept apart from LED Driver and other leads (ideally 5 ‒ 10 cm distance)
• Max. lenght of output wires is 2 m.
• Incorrect wiring can damage LED modules.

Mounting screw specifications and torque

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

Replace LED module

1. Mains off
2. Remove LED module
3. Wait for 5 seconds
4. Connect LED module again

Installation requirements

• The installation ambient temperature of the drive shall not exceed the value of Ta at any time.

Please do not stack the products. The distance between two products should be ≥15cm so as not to affect heat dissipation and the lifespan of the products.
