Battery life Controller power OFF
Approx. 3 years under standard
conditions
Controller power ON
Approx. 10 years under standard
conditions
Rated power supply
voltage
100 to 240 Vac, 50/60 Hz
Allowable power supply
voltage
90 to 264 Vac, 50/60 Hz
Power consumption
30 VA max.
Power ON rush current
30 A max., 10 ms (under operating conditions)
Handling Precautions
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 2 s after power ON.
Power ON operation
Reset time:
15 s max. (time until normal operation possible under
normal operating conditions)
Allowable transient
power loss
20 ms max. (under operating conditions)
