Hold-up time

20 ms @175 W load at nominal line

Overload protection

Short circuit protection on all outputs. Case

overload protected @ 110-145% above peak

rating

Overvoltage protection

Tracks outputs 1, 3 & 4; 15 to 35%

Standby output

5 V @ 200 mA regulated ±5%

Logic Control

AC power failure

TTL logic signal goes high 100 - 500 msec

after V1 output; It goes low at least 4 msec

before loss of regulation

Remote inhibit

Requires contact closure to inhibit outputs

Remote sense

Compensates for 0.5 V lead drop min. Will

operate without remote sense connected.

Reverse connection protected.

DC-OK

TTL logic signal goes high after main output

is in regulation. It goes low when there is a

loss of regulation
