Environmental Specifications
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 protected.
DC - OK TTL logic signal goes high after main output is in regulation. It
goes low when there is a loss of regulation.
Notes:
1. Specifications subject to change without notice.
2. All dimensions in inches (mm), tolerance is ±0.02”.
