Performance

Typical efficiency vs load

Tested with a load of 12 LEDs in series, programmed for 500mA and at 25 ºC ambient temperature. The measurements below 20W were performed by dimming the light output.

LED driver protection

Thermal The LED output current is automatically decreased whenever the internal driver temperature exceeds a factory preset temperature. The LED output current is increased once the internal driver temperature drops below the preset temperature threshold. If the internal driver temperature continues to increase, despite a decrease in output current, the LED driver will eventually shut down.

LED output short circuit

The LED output current is cut off whenever the LED driver detects a shortcircuit. The LED driver will attempt a restart every 400ms after a short-circuit is
detected.

Operating ambient temperature (Ta) range -20 ºC to +50 ºC for output current ≤ 900mA -20 ºC to +43 ºC for output current > 900mA

Maximum operating case temperature (Tc max) 80 ºC

Acoustic noise – steady state <24dBA (Class A)

Lifetime 50,000 hours at a maximum case temperature (Tc) of 80 ºC
