PERFORMANCE
2.2 Efficiency
The power supply is a minimum of 72% efficient under typical load. The “Energy Star” efficiency of the power supply is a minimum of 50% when the AC input power is 60W.
2.3 Remote ON/OFF control
The power supply DC outputs (with the exception of +5 VSB which is always available) are enabled with an active-low, TTL-compatible signal (“PS-ON”), When PS-ON is pulled to TTL low, the DC outputs are enabled. When PS-ON is pulled to TTL high or open-circuited, the DC outputs are disabled. PS-ON may be active by either electronic means or a mechanical switch.
2.4 Overshoot at TURN-ON/TURN-OFF
The output voltage overshoot upon the application or removal of the input voltage is less than 10%.
2.5 Hold-up Time
The power supply will maintain output regulation despite a loss of a minimum of 16 ms while under full load. Test to be performed at nominal input voltage.
2.6 Power Good Signal
A “power good” signal is asserted by the supply to indicate that the +5VDC output is within regulation limits.
