MATelec HydroTOUCH FPC-43120-J Mild Steel 18.5 kW Variable Speed Single Pump Controller

For reliable hot water circulation, the MATelec HydroTOUCH FPC-43120-J varies the speed of one 18.5 kW pump and links easily to SCADA over Modbus RTU RS485. This controller operates on a standard three-phase power supply of 400 Vac at 50 Hz, adjusting VSD speed based on live transducer inputs. Based on real-time sensor feedback, the system adjusts pump performance to maintain the configured operating conditions.

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.

An integrated Setup Wizard on the 7-inch touchscreen HMI simplifies 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.
