LPQ170 Series Data Sheet

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

-40 °C to +85 °C

Electromagnetic susceptibility

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.
