Test Procedure for the NCL30082SMRTGEVB Evaluation Board Test Procedure Equipment Needed AC Source – 90 to 135 V ac 50/60 Hz Minimum 500 W capability AC Wattmeter – 300 W Minimum, True RMS Input Voltage, Current, Power Factor, and THD 0.2 % accuracy or better DC Voltmeter – 300 V dc minimum 0.1 % accuracy or better DC Ammeter – 1 A dc minimum 0.1 % accuracy or better LED Load – 75 V @ 0.1 A. A constant voltage electronic load is an acceptable substitute for the LEDs as long as it is stable. Test Connections 1. Connect the LED Load to the red(+) and black(-) leads through the ammeter shown in Figure 8. Caution: Observe the correct polarity or the load may be damaged. 2. Connect the AC power to the input of the AC wattmeter shown in Figure 8. Connect the white leads to the output of the AC wattmeter 3. Connect the DC voltmeter as shown in Figure 8. AC Power Source AC Wattmeter UUT DC DC LED Test Load Figure 8. Test Set Up Note: Unless otherwise specified, all voltage measurements are taken at the terminals of the UUT. Functional Test Procedure 1. Set the LED Load for 75 V output. (Can use 65V LED Load with 100Ω Resistor in Series). 2. Set the input power to 120 V 60 Hz. Caution: Do not touch the ECA once it is energized because there are hazardous voltages present. 3.
