Remote Sense

Remote Sense is provided on all outputs and will

compensate for 0.7V 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 ‘1’ (or open)

signal and turned off by a switch closure or TTL logic ‘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 200

µSec 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 zero at least 5msec before loss of DC output. Upon

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

regulation referenced to (-) sense terminal. Consult the

factory for other options.

DC Power Good Signal

Upon a ±10% loss of regulation on any output, the DC

Good signal drops to a logic zero referenced to (-) sense

terminal. Consult the factory for other options.

Over Temperature Protection

Internal thermal switch turns off power supply if overheating

occurs and automatically restarts when temperature drops

below threshold.
