MATelec HydroTOUCH FPC-43120-B Mild Steel 1.5 kW Variable Speed Single Pump Controller

When a tank needs controlled filling, the MATelec HydroTOUCH FPC-43120-B manages one pump at 1.5 kW using feedback from its 4-20 mA level transducer. It functions on an electrical supply of 400 Vac at 50 Hz, automatically regulating motor frequency of the connected pump to align with demand. The unit maintains consistent flow, pressure, or level based on real-time feedback from connected analog transducers and digital switches.

Motor frequency is controlled using PID speed control in pressure, flow and temperature modes, or proportional speed control in level mode. The controller adjusts the connected pump speed in response to system feedback to support stable operation.

A 7-inch touchscreen HMI hosts a Setup Wizard to simplify system commissioning. The diagnostic screens display graphical overview screens, power and water usage charts, and timestamped alarm logs for system maintenance.

Standard terminal connections accommodate dual analog 4-20 mA inputs, up to five 24 Vdc digital inputs, and a pulse flow meter. Standard RCD protection is not recommended because VSD EMC filtering can cause nuisance tripping. If RCD protection is required, Type B RCDs must be used with consideration of VSD earth leakage current.
