Remote Sense

Power Fail Signal

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.

Upon AC input voltage removal, the power fail signal drops

to logic zero at least 5msec before loss of DC output. On

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

regulation. Consult the factory for other options.

Remote On/Of

N+1 Load Share

Output #1 has active load sharing circuitry. Units will load

share within 1.5% of Maximum Rated Load.

The power supply is turned on with aTTL 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.

OverTemperature Protection

OverVoltage Protection

Output #1: 6.5V 0.5 V^DC.

Thermal switch turns off power supply if overheating occurs

and automatically restarts.

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

Safety

Over Current Protection

UL Recognized: UL File Number E14675 (1950 & 1012)

CSA Certified: CSA File Number LR 9070-154C

(C22.2 No.234-M90, Level 6)

Individual current limit on all outputs. Automatic recovery

upon fault removal.

TUV License Number: R9576031 (EN60950) (IEC950)

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.

Cooling

The unit is designed to operate with 30 CFM of airflow.

Output Isolation

All outputs are fully isolated.
