Max. Input Current
2.4 Inrush Current
The power supply must meet inrush requirements for any rated AC voltage, during turn on at any phase
of AC voltage, during a single cycle AC dropout condition, during repetitive ON/OFF cycling of AC, and
over the specified temperature range. The peak inrush current shall be less than the ratings of its critical
components (including input fuse, bulk rectifiers, and surge limiting device).
2.5 Efficiency
SX700-LPT provides an efficiency of 90% at20% load, 92% at50% load, 89% at100% load under115V/60Hz
and 230V/50Hz condition.
Maximum continuous total DC output power should not exceed 700W.
Maximum continuous combined load on +3.3VDC and +5VDC outputs shall not exceed 120W.
Maximum combined load on 12V outputs shall not exceed 700W.
NOTE:
Noise test should be measured with 20 MHz bandwidth frequency oscilloscope. The output terminal shall
add a tantalum capacitor of 10uF in parallel with a ceramic capacitor of 0.1uF.
3.2 Remote On/Off Controlled mode
The PSON# signal is required to remotely turn on/off the power supply, PSON# is an active low signal that
turns on the output power rails. When this is not pulled low by the system, or left open, the outputs (except
the +5VSB) turn off. This signal is pulled to a standby voltage by a pull-up resistor internal to the
power supply.
