Overvoltage Protection

Overvoltage protection on all outputs.

%

Unit latches off when overvoltage is detected.

AC input must be recycled to reset.

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

System shutdown due to excessive internal temperature, automatic reset.

Output Good

Signal indicates output good when at a TTL high state. If any of the outputs are

<14% or >14% of the nominal output voltage, then this signal will make a

transition to a TTL low state. Pull-up resistance is 1k

to 5V Vcc and minimum

sink current is 50 mA. Maximum voltage at low state is 0.5 V.

Input Power Fail Warning

TTL-compatible signal. Pull-up resistance is 1k

to 5V Vcc and minimum

sink current is 50 mA. Maximum voltage at low state is 0.5 V. Time before regulation

in redundant applications.

Current Share

Available on all outputs. Accuracy of shared current with up to 6 parallel units.

10

%
