MATelec HydroTOUCH FPC-43320-E Mild Steel Three Phase 4 kW Variable Speed Triplex Pump Controller

Pressure boosting across three pumps gets responsive 4 kW control from the MATelec HydroTOUCH FPC-43320-E, guided by a 4-20 mA level transducer. Operating on a three-phase power supply of 400 Vac at 50 Hz, this controller manages triplex-pump setups to ensure system parameters are met. The unit maintains consistent flow, pressure, or level based on real-time feedback from connected analog transducers and digital switches.

To maintain system efficiency, this panel incorporates advanced PID control parameters that adjust pump speed in response to system feedback. Staggered operation is programmed into the system to prevent electrical surges and reduce mechanical pipe shock during pump cycling. Run hours are balanced across all available drives through built-in duty alternation and automatic sharing protocols.

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.
