4.3Other Specification
4.3.1Inrush Current:
55A max. when AC input 115Vac at 25oC cold start. 110A max. when AC input 230Vac at 25oC cold start.
4.3.2Power Efficiency:
80% (min.),up to 85% 115VAC - Full load 80% 230VAC - Full load 85%
4.3.3Power Factor: PF>0.9
4.3.4Note:
The continuous total output power is 750W max.
The combined power of +5V and +3.3V is 180W max. Peak currents may last up to 12 seconds with not more than one occurrence per minute.
Total combined +12V output load not exceed 60A.
4.3.5
16msec (minimum) at 80% of full load at 230Vac input.
4.3.6Power Good Delay:
4.3.7Power Fail Delay: >1 msec.
4.3.8
4.3.9Rise Time:
20ms max at full load.
4.4Protection
When OCP, OVP or short protection is triggered, the main outputs will be latched off. The main outputs can be reset by cycling the DC remote on/off or AC power. +5Vsb output is auto recovery when fault condition removed.
4.4.1Over Current Protection
Not over 240VA for every output voltage.
4.4.2Over Voltage Protection +3.3V output 4.5 Vmax +5.0V output 7.0 Vmax +12.0V output 15.6 Vmax
