UNITS

Overvoltage Protection

Overvoltage protection on all outputs except V5.

120

140

%

Unit latches off when overvoltage is detected.

AC input must be recycled to reset. V5 is protected by a 6.2V ±5%, 2W Zener diode.

Overload Protection

Fully protected against output overload and short circuit. Automatic recovery upon

removal of overload condition. All outputs are individually current limited.

Overtemperature Protection

Power supply shuts down due to excessive internal overtemperature at the output

converter’s primary switching transistors. Power supply resets automatically upon

removal of the overtemperature cause.

Output Good

TTL-compatible global Output Good signal. The signal is active when any of the

V1-V4 outputs drop >14% below nominal. Source impedance is 1k .

Input Power Fail Warning

Open collector signal. Time before regulation dropout due to loss of input

5ms

power. May be used as independent PSOK signal in redundant applications.

Current Share

Available on all outputs except V5. Accuracy of shared current with up

10

%

to two parallel units. Single wire current share is provided. For paralleling

more than two units, consult factory.

Remote Sense

Available on all outputs except V5. Total voltage compensation for cable losses with

500

mV

respect to the main output.
