Inverters - 4-20 mA variable frequency drives for plunger pumps P and ST-P

Frequency converters

Frequency converter (inverter) — electronic device for changing the frequency of electric current (voltage).

Automation of performance control of plunger pumps is possible by changing the frequency of the electric current. This is possible with an external frequency converter, which will change the speed of the electric motor.
