LPS172 Datasheet, PDF (2/4 Pages) Emerson Network Power – Active power factor correction

LPS170 Series Data Sheet
Logic Control
Power failure
Remote inhibit
Remote sense
DC - OK
TTL logic signal goes high 100 - 500 msec after V1 output; It goes low at least 4 msec before loss of regulation
Requires contact closure to inhibit outputs
Compensates for 0.5 V lead drop min. Will operate without remote sense connected. Reverse connection
protected.
TTL logic signal goes high after main output is in regulation. It goes low when there is a loss of regulation
