(-C) (-CF) (CEF)

Supervisory output

5 V @ 100 mA regulated; 12 V @ 500 mA

Adjustment range

2:1 wide ratio

Hold-up time

20 ms @ 250 W load, 115 VAC nominal line

Overload protection

Short circuit protection on all outputs. Case overload protected @

10 - 145% above peak rating

Overvoltage protection

5 V output: 5.7 to 6.7 Vdc.

Other models 10% to 25% above nominal output

Logical Control

Power failure

TTL Logic signal goes high 50 - 150 msec after 5 V output. It goes low at

least 4 ms 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 the output. It goes low when there

is loss of regulation.

Remote sense

Compensates for 0.5 V lead drop minimum, will operate without remote

sense connected. Reverse connection protected
