Power Fail Signal

Remote Sense

Upon AC input voltage removal, the power fail signal drops

to logic zero at least 10msec before loss of DC output.

Upon AC input turn-on, signal remains low until output is in

regulation. Consult the factory for other options.

Remote Sense is provided and will compensate for 1.0V

of line drop. Remote Sense leads are protected against

open, short and reversal.

Remote On/Off (Optional)

N+1 Load Share

Output has active load sharing circuitry. Units will load

share within 1% of the 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.

Over Temperature Protection

Thermal switch turns off power supply if overheating occurs

and automatically restarts.

Over Voltage Protection

Output #1: 15% of nominal voltage is typical.

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

Safety

UL Recognized: UL File Number E13164 (1950)

CSA Certified: CSA File Number LR 9070C

(C22.2 No950, Level 6)

Over Current Protection

Automatic recovery upon fault removal.

TUV License Number: R9773309 (EN60950) (IEC950)

Transient Response

The peak output voltage excursion will not exceed 2% and

will recover within 1% in 200 μsec for a 25% step load.

Cooling

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

Reverse Voltage Protection

DC Power Good Signal

The output is protected to rated load.

The signal is activated by a ±10% loss of regulation Active

low or high;TTL Level; common with (-) sense. Consult the

factory for other options.
