Test Procedure for the NCP1027ATXGEVB 04/20/2006 Figure 1: Test Setup Table 1: Required Equipment Yokogawa Power Meter WT210 ac Power Supply, 85 Vac – 265 Vac, 1 A Electronic Load, 5 V up to 3 A NCP1027ATX Evaluation Board Test Procedure: 1. Connect the test setup as shown in Figure 1. 2. Apply an input voltage, 85 Vac < VIN < 265 Vac, 50 Hz or 60 Hz. 3. Connect electronic load to output connector. 4. Test the conditions given in Table 2. Multimeter Table 2: Desired Results Measurments 1 Output Voltage 2 3 4 5 Input consumption at high line and no load Input consumption at high line line and low load Output voltage at high line and full load Output voltage at low line and full load 6 Brownout detection Maximum output at low 7 line Maximum output at high 8 line Conditions VIN = 100 Vac, no load VIN = 230 Vac, no load VIN= 230 Vac, Iload= 0.1 A VIN = 230 Vac, Iload = 2.5 A VIN = 85 Vac, Iload = 2.5 A VIN ↓ until VOUT = 0 V, IOUT = 2 A VIN = 85 Vac, IOUT ↑ VIN = 230 Vac, IOUT ↑ Results Comments VOUT = 5 V ± 5% PIN = 0.09 W ± 15%, VOUT = 5 V PIN = 0.83 W ± 10% VOUT = 5 V POUT = 0.5 W No load measurment can fluctuate, run WT210 in average mode VOUT = 5 V ± 5% VOUT = 5 V ± 5% VIN = 56 Vac ± 15% POUTmax = 14 W ± 15% POUTmax = 18 W ± 15% Output voltage must collapse under 56 Vac Output voltage must collapse above 14 W Output voltage must collapse above 18 W
