Transient response

Output voltage returns to within 1% in less than

2.5 mS for a 50% load change. Peak

transient does not exceed 5%.

Overshoot

Turn-on and turn-off overshoot shall not exceed

5% over nominal voltage.

Remote Inhibit

Designated as RMSW on the CN1. Requires a low signal to inhibit the output.

LED display

When green (LED1) is on the power supply is operating normally.

Power Good

Designated as PG on the CN1. This signal

goes high 100-500 mS after the output reaches regulation.

It goes low at least 1 mS before loss of regulation.

Protection Circuit

Parameter

Conditions/Description

Input Fuse

Built-in ac fuse. A blown fuse usually indicates permanent

damage to the power supply serviceable by factory only.

Overload

Current limiting starts at 110-140% of the rated output current in foldback mode and

recovers automatically.

Short circuit

Short circuit can be continuous. Recovers automatically upon removal of short.

Output Over-voltage

Output is protected agaist overvoltage. Unit shuts down and latches

when voltage at output terminals exceeds 130%. AC input needs to be

reset to restart the power supply.

Over temp.

Power supply shuts down when temperature is in excess of 85 ºC. Auto recovery.
