MATelec HydroTOUCH FPC-43220-H Mild Steel 11 kW Variable Speed Dual Pump Controller

The MATelec HydroTOUCH FPC-43220-H gives filtration plants responsive control of two 11 kW pumps, with dual transducer inputs available for live system feedback. 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.

Motor frequency is controlled using PID speed control in pressure, flow and temperature modes, or proportional speed control in level mode. Staggered operation is programmed into the system to prevent electrical surges and reduce mechanical pipe shock during pump cycling. 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.
