Variable frequency controller

Accept external control signals, through changing the frequency of the power supply control motor speed, change the metering pump stroke frequency, thereby regulating the flow.
Power supply: 220V/50HZ; 380V/50HZ
Control signal: 4 ~ 20mA
Motor switch controller (VARIPULSE):
To drive / stop control of three-phase motor, change the stroke frequency, thus regulating metering pump flow. Power supply: 220V/50HZ.
