Remote Sense

Remote Sense is provided on Output #1 and will

compensate for 0.3V of line drop. Remote Sense leads

are protected against open, short, and reversal.

Remote On/Off

The power supply is turned on with a TTL logic level ‘1’ (or

open) signal and turned off by a switch closure or TTL logic

level ‘0’ referenced to (-) sense terminal. Consult the factory

for other options.

Over Voltage Protection

The power supply will latch off until AC power is cycled.

Over Current Protection

Individual current limit on all outputs. Automatic recovery

upon fault removal.

Reverse Voltage Protection

All outputs are protected to rated load.

Transient Response

The peak output voltage excursion on the main output will

not exceed 2% and will recover within 1% in 50 mSec for a

25% load step change. On outputs #2-5, the peak output

voltage excursion will not exceed 1% for a 25% load step

change.

Output Isolation

All outputs are fully isolated.

Power Fail Signal

Upon AC input voltage removal, the power fail signal drops

to logic level ‘0’ at least 5msec before loss of DC output.

Upon AC input turn-on, signal remains low until outputs are

in regulation. Consult the factory for other options.

DC Power Good Signal

The signal drops to logic level ‘0’by a ±10% loss of regulation

on any output, common with Output #1 (-) sense. Consult

the factory for other options.

Over Temperature Protection

Internal thermal switch turns off power supply if overheating

occurs and automatically restarts. Automatic restart when

temperature drops below threshold.
