Demo Board Test Procedure
the dc load to the J2 connector. Place a Digital Voltage Meter
(DVM) directly across the J2 output terminals. Set the ac
power source to 115 Vac, and turn on the ac source. The
NCP1230 controller will turn−on and supply 19 Vdc to the

load (refer to Table 1 for load regulation). Vary the load from
0 to 4.73 Adc and monitor the output voltage. Adjust the ac
power source from 85−265 Vac and monitor the output
voltage. Set the ac power source to 230 Vac, and disconnect
the dc load and monitor the standby power (refer to Table 4
for the standby power limits).
