9.5. 390 V to 358 V && 358 V to 390 V at Loading
Test Condition:
Load: 100% load, during the loading-point to change, the PFC bulk voltage steps up to
390 V from 358 V or steps down to 358 V from 390 V.
Test Results:
Input Voltage Loading (A) Loading (%)
115 V / 60 Hz 390 V to 358 V 15.37 61.5
230 V / 60 Hz 390 V to 358 V 16.09 64.4
115 V / 60 Hz 358 V to 390 V 17.9 71.6
230 V / 60 Hz 358 V to 390 V 18.7 74.8
9.6. 390 V to 358 V && 358 V to 390 V at Vrms
Test Condition:
Load: 100%. Load, during the AC input to change, the PFC bulk voltage steps up to
390 V from 358 V or steps down to 358 V from 390 V.
Test Results:
Loading & Bulk Voltage Input Voltage
Loading = 100% 390 V to 358 V 235 V
Loading = 100% 358 V to 390 V 253 V
9.7. Hold up Time
Test Condition:
After AC power off, the output voltages should stay at nominal value for at least 17 ms.
Test Results:
