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
