MATelec HydroTOUCH FPC-43120-K Mild Steel 22 kW Variable Speed Single Pump Controller

Chiller supply flow can be tuned to real demand with the MATelec HydroTOUCH FPC-43120-K, a 22 kW single-pump controller paired with a 16 bar pressure transducer. 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.

To maintain system efficiency, this panel incorporates advanced PID control parameters that adjust pump speed in response to system feedback. 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. 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.
