DC OK
Remote sense
TTL logic signal goes high 100-500 msec
after main output. It goes low at least 4
msec before loss of regulation
Requires an external contact closure to
inhibit outputs
TTL logic goes high after the output is in
regulation. It goes low when there is loss
of regulation.
Compensates for 0.5 V lead drop min.
Will operate without remote sense
connected. Reverse connection protected.
Electromagnetic susceptibility: Designed to meet
EN61000-4, -2, -4, -5, -11 Level 3
Humidity: Operating; non-condensing
10% to 90%
Vibration: Three orthogonal axes, sweep at
1 oct/min, 5 min. dwell at four major resonances
2 G peak 8 Hz to 500 Hz, operational
Storage temperature: -40° to 85°C
Temperature coefficient: ±.04% per °C
MTBF demonstrated: >1M hours at full load and
25°C ambient conditions
