Notes:
1. Inrush current is given for a cold start
at 25°C.
2. Total Harmonic Distortion (THD) is
specified with an input of 230 VAC/50
Hz at full load.
3. Turn on delay is specified at full load.
4. Ripple & noise is measured at 20 MHz.
Connection to the unit is made with a 0.1 µF
ceramic capacitor and a 22 µF electrolytic
capacitor connected in parallel.
5. Life expectancy is calculated at 230 VAC,
full load and a case temp of +70°C.
6. Recovery from an over voltage fault is
automatic.

Dimming Mode:
B Model
With the
LDC-120
“B” model, the output current level can be adjusted (Dimmed) by three different methods; Resistive, Analog or
Digital. Adjustments are made using the +DIM and -DIM inputs.
Resistive:
Connect a 0.1 to 10 k resistor between the DIM+ (Blue) and DIM- (White) wires

.
The -DIM (White) and -LED (Black) wires should not be connected.
2. The Dimming function will not turn the lighting fixture totally off. For more info on how to do this, please contact the factory
