Remote Sense

Remote Sense is provided on Output #1 and will

compensate for 0.7V of line drop. Remote Sense leads

are protected against open, short and reversal.

Remote On/Off (Optional)

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.

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.

Active Inrush Current Limiting

Inrush current is independent of ambient temperature.

Transient Response

The peak output voltage excursion will not exceed 2% and

will recover within 1% in 200

μsec for a 25% load step

change.

Over Temperature Protection

Thermal switch turns off power supply if overheating occurs

and automatically restarts.

Safety

Safety Certified to UL/CUL to 1950, File Number E131694.

TUV to EN60950/IEC 950.
