Overload protection

Short circuit protection on all outputs.

Case overload protected @ 110-145%

above peak rating

Overvoltage protection

5 V output: 5.7-6.7 VDC.

Logic Control

Power failure

TTL logic signal goes high 50-150 msec

after 5 V output. It goes low at least 4

msec before loss of regulation

Remote on/off

Requires an external contact (N.O or

N.C) to inhibit outputs

DC-OK

TTL logic goes high 50-150 msec after

5 V output. It goes low when there is

loss of regulation.

Remote sense

Compensates for 0.5 V lead drop min.

Will operate without remote sense

connected. Reverse connection

protected.
