PWM 400 is an integrated system for the variable speed control (INVERTER) of the electric pumps, capable of maintaining the pressure constant as the flow rate varies.
Through the different possible settings, and the availability of contacts of the input and configurable output, it is possible to adapt the operation of the PWM system to the needs of various plants.
PWM 400 pilot electric pumps with induction motors standard three-phase, and is powered by a three-phase line. The supply voltage of the motor of the electric pump is installed must be 400V 50Hz three-phase. The users connected to the PWM 400 must not exceed 7.5 Arms as phase current.
