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 sense

Designated as RS+ and RS- on the CN3. Total voltage compensation for cable losses with

respect to the main output. (NOT available for current sharing models.)

Remote Inhibit

Designated as RSW on the CN3. Requires a low signal to inhibit the output.

LED display

Green - the power supply is operating normally.

(LED 1)

Orange - when any protection occurs or when Remote Inhibit is in effect.

Power Good

Designated as PG on the CN3. This signal

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

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

Current Sharing

Designated as CSH on (CN3), use in parallel for forced current sharing function.

Accuracy of shared current with up to 4 parallel units is within 10% at full load.

Current Monitor

Disignated as CMN on (CN3) for current sense purpose. CMN is a 0.5 to 3VDC output

voltage to represent a linear 0% to 100% output current.

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.

Input under-voltage

Power supply shuts down when ac input is under

80 VAC. When ac line reappears over 86 +/- 5 VAC,

the power supply restarts automatically.

Overload

Current limiting starts at 110-140% of the rated output current 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.
