MATelec HydroTOUCH FPC-43420-H Mild Steel Three Phase 11 kW Variable Speed Quad Pump Controller

For filtration systems with four pumps, the MATelec HydroTOUCH FPC-43420-H provides 11 kW variable-speed control based on a supplied 16 bar pressure transducer. Operating on a three-phase power supply of 400 Vac at 50 Hz, this controller manages quad-pump setups to ensure system parameters are met. Connected instrumentation feedback allows the control module to adjust VSD frequency dynamically, ensuring efficient water management.

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.

A 7-inch touchscreen HMI hosts a Setup Wizard to simplify 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.
