Standards for LED drivers, LED modules and LED luminaires

OPTOTRONIC LED drivers for indoor application

General information on standards

All OPTOTRONIC drivers are designed to meet or exceed applicable standards for their use in lighting applications.

Safety

The safety requirements for LED drivers are defined in EN 61347-2-13. OPTOTRONIC indoor drivers are available in two insulation classes:

  • SELV drivers (double/reinforced isolation between inputand output, LEDset)
  • Non-isolated drivers (no isolation between input andoutput, LEDset)

OPTOTRONIC LED drivers have the following safety features:

  • Overload protection
  • Short-circuit protection
  • Partial-load/no-load-safe
  • Overtemperature operation
  • Input overvoltage and surge protection

Performance

The performance standard EN 62384 defines the optimal operation of LEDs with LED drivers, ensuring that LEDs are only operated within their specified operating parameters. This guarantees best performance and maximum lifetime of suitable LED modules. All OPTOTRONIC drivers with the ENEC mark are approved according to EN 62384.

EMC (electromagnetic compatibility)

EMC is specified as a series of different test criteria. These are radio interference suppression (EMI), immunity to interference and voltage fluctuations, flicker and harmonic content (up to the 39th harmonic). Harmonic content of the mains current Lighting equipment is subjected to restrictions on harmonics. The maximum permissible limits are defined in the standard EN 61000-3-2, classification in class C for lighting equipment. All OPTOTRONIC drivers fulfill the strict harmoniclimits below 25 W and above 25 W, even though LED products below 25 W are excluded from the requirements. This means that OPTOTRONIC drivers already fulfill the upcoming stricter requirements for LED products below 25 W. This is important even for large installations because it does not matter if 1000 low-wattage luminaires or 250 high-wattage luminaires have to be installed.

Immunity

The immunity requirements are specified in EN 61547. This guarantees protection against interference from external high-frequency fi lds, discharge of static electricity and transient overvoltages on the mains supply.

Radio interference

The requirements, e.g. limits for conductive and radiated disturbances, are defined in EN 55015. The length of outputcables must not exceed the values specified in the product datasheets to meet the requirements of radio interference suppression.

Note: The luminaire manufacturer is responsible for measuring and verifying EMI compliance of the complete luminaire as the level of radio interference will vary depending on the luminaire construction. Especially primary and secondary cable lengths and their routing may have a significant effect on radio interference.
