Battery life Controller power OFF Approx. 3 years under standard conditions
Controller power ON Approx. 10 years under standard conditions
90 to 264Vac, 50/60Hz
30VA max.
15A max., 10ms (under operating conditions)
When starting up a number of DCP31s simultaneously, ensure ample power is supplied
or stagger startup times. Otherwise, the controllers may not start normally due to inrush
current induced-voltage drop. Voltage must stabilize within 2s after power ON.
Reset time: 15s max. (time until normal operation possible under normal operating
conditions)
20ms max. (under operating conditions)
Min. 20MΩ across power terminal (1) or (2) and ground terminal (3) (using a 500Vac
megger)
1500Vac 50/60Hz for 1min across power terminal and ground terminal
1500Vac 50/60Hz for 1min across relay output and ground terminal
500Vac 50/60Hz for 1min across non-power terminal and ground terminal
