MATelec HydroTOUCH FPC-43220-G Mild Steel 7.5 kW Variable Speed Dual Pump Controller

Purpose-built for process water control, the MATelec HydroTOUCH FPC-43220-G synchronises two 7.5 kW pumps and reads flow through a pulse meter. This panel manages the operation of dual-pump configurations using a three-phase power supply of 400 Vac at 50 Hz. It monitors input signals continuously to adjust motor speed and maintain precise system parameters according to the user setpoint.

To maintain system efficiency, this panel incorporates advanced PID control parameters that adjust pump speed in response to system feedback. Staggered pump starting and stopping sequences are programmatically executed to prevent electrical current surges and mechanical water hammer. Built-in duty sharing and alternation protocols balance operating hours across all connected pumps to extend equipment service life.

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.
