FRIWO LED Drivers and LED Power Supplies UK

Nearly all LEDs operate from low voltages and require a Power Supply Unit to reduce the mains voltage supply down to the voltage or current that is required by the LED product. PSUs are either constant voltage or constant current (See FAQs).

LED drivers are electrical devices that regulate the power to an LED or string(s) of LEDs.

Different from conventional power supplies

What makes a driver different from conventional power supplies is that an LED driver responds to the ever changing needs of the LED(s) by supplying a constant amount of power to the LED as its electrical properties change with temperature. Without the proper driver, the LED may become too hot, become unstable resulting in performance issues or most likely have a cataclysmic failure.

FRIWO LED Drivers - innovative, efficient and reliable

Designed and manufactured by this world renowned power supply manufacturer FRIWO have developed a range of LED drivers with innovation, efficiency and reliability at their centre.

  • One Single Driver for both Constant Current and Constant Voltage (possible due to the upright current curve - see diagram below)
  • Input Range of 198-264V AC at 50-60Hz
  • Output protected against overvoltage, over current and short circuit.
  • Active PFC with a power factor ≥ 0.95
  • Efficiency ≥ 86%
  • Compact Size - (W30mm x H21mm - great fit for luminaries)
  • Secondary shut off with small standby losses of 0.1W
  • In CC mode the LED Driver can be dimmed directly with a PWM signal (TTL level 0-5V/600Hz; connection: CTRL and GND).
  • CC mode offers possibility of external power reduction. (connection: Resistor 100kOhms - 10MOhms from x to CTRL).
  • Connectable via clamps for leads up to 1.5mm.
  • Protection end caps available
  • Protection class II
  • IP20 as standard (IP67 available)
  • In house trimming allows for customer specific output requirements.
