Power Ratings

Efficiency Ratings, 3.3V, 5V and 12V Rails

Input Requirements

Single input source (master) or two input sources (master + slave) can be used.

Master/slave input:

• 16V to 24V, typical 19V regulated, min=1A, max=25A (load dependent).
• Over voltage shutdown will occur at about 24

Input Source Selection

The fuse (F1) on board is used to select the number of input sources.

• Mode of only one input source (master only): mount the fuse on F1, and connect your power adapter to input A or B.
• Mode of two input sources (master + slave): DO NOT mount the fuse on F1, and connect your two power adapters to input A and input B, respectively.

Overload Protection

Over load protection will be effected when either of the loads (+12V, +5V and +3.3V) exceeds 150% Max Load.

Turn-on Delay

After turning on, at least 20 ms will be needed for the rise of +5VSB output voltage (measured from 10% to 95%) to reach its peak.

Remote ON/OFF Control (PS_ON)

Logic level on PS_ON pin is LOW:  Output voltage of PSU is enabled

Logic level on PS_ON pin is HIGH:  Output voltage of PSU is disabled

Power Good Indicator (PWR_OK)

Logic level on PWR_OK is HIGH: Power output of PSU is ready

Logic level on PWR_OK is LOW: Power output of PSU is not OK (DC input is smaller than 16V or larger than 20V or other fault conditions)
