Electrical
Operating voltages: 85-264 V AC, 47 - 440 Hz
Power consumption: 40 watts
Backup power: Rechargeable NiCad pack maintains
operation after power loss for 5 minutes, allowing
the monitor to record outage, reclosure attempts,
and to resume monitoring upon restoration of
power. Real time clock is backed up using a lithium
battery with 10-year life.
