LPQ142 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 Requires contact closure to inhibit outputs
Remote sense
Compensates for 0.5 V lead drop min. Will operate without remote sense connected. Reverse connection proteced.
DC - OK TTL logic signal goes high after main output is in regulation. It goes low when there is a loss of regulation
Environmental Specications
Operating temperature 0° to 50 °C ambient. Derate each output 2.5% per degree from 50° to 70 °C (except for -C version).
Storage temperature -40 °C to +85 °C
Temperature coefcient ±0.4% per °C
Electromagnetic susceptibility Designed to meet IE61000-4, -2, -3, -4, -5, -6, -8, -11, Level 3
