The current version of the standard for general safety requirements for equipment for lamps requires galvanic isolation (insulation) of control circuits to all other circuits of the device. This also applies to PWM and 0-10V interfaces. The constant current LED drivers of the BLD series from the manufacturer uPowerTek meet the requirements of the EN61347-1 standard for all power classes, from 40-480W. Other features of this product family include:

- Wide input voltage range: 90-305V AC or 127-420V DC
- High surge immunity: 10KV
- Lifetime : 100 000 h @TC 75°C
- Dimmable via : 0-10V/PWM/DALI 2.0/DMX
- Output current : NFC programmable
- 12V 300mA DC output to drive sensors or Bluetooth interfaces
