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

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.

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
- Mains off
- Remove LED module
- Wait for 5 seconds
- 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.
