MATelec HydroTOUCH FPC-43120-D Mild Steel 3 kW Variable Speed Single Pump Controller

Designed around stormwater removal, the MATelec HydroTOUCH FPC-43120-D controls a single 3 kW pump and accepts feedback through dual transducer inputs. This panel manages the operation of single-pump configurations using a three-phase power supply of 400 Vac at 50 Hz. 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 and Setup Wizard simplify system commissioning. Users can monitor real-time power and water usage graphs, historical trend plots, and system event logs directly from the screen.

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.
