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. If an overvoltage fault occurs, the protection circuit will latch off the output. A power reset is required to recover.

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 Input Frequency 10 k 20 k 30 k 40 k 50 k 60 k 70 k 80 k 90 k 100 k Open Percentage of Rated Current 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% 95~105% Analog: Apply 1 VDC to 10 VDC level between the DIM+ (Blue) and DIM- (White) wires Adjust Voltage Percentage of Rated Current 1 VDC 2 VDC 3 VDC 4 VDC 5 VDC 6 VDC 7 VDC 8 VDC 9 VDC 10 VDC Open 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% 95~105% Digital: Apply a PWM signal (100 Hz - 3 kHz) between the DIM+ (Blue) and DIM- (White) wires Duty Cycle 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% Open Percentage of Rated Current 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% 95~105% Notes: 1.
