RM-PL3 power consumption limiter is used for protecting devices
against overpower, overvoltage and undervoltage faults. It calculates
the power consumption of using device through detecting input voltage
and current values .
The output relay of RM-PL3 will close after Ton delay. When power
consumption detected is higher than P> setting value, the output relay
opens after Toff delay. When an input voltage fault was detected, the
output relay opens. If continuous 5 times such faults. RM-PL3 begin a
10minutes delay and enter output state after the delay is elapsed.
RM-PL3 can be widely applied for power consumption limiting of
heating system, lighting, motor and generator etc .
