MATelec HydroTOUCH FPC-43420-G Mild Steel Three Phase 7.5 kW Variable Speed Quad Pump Controller

Process water flow can be coordinated across four 7.5 kW pumps with the MATelec HydroTOUCH FPC-43420-G and monitored remotely over Modbus RTU RS485. 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. Based on real-time sensor feedback, the system adjusts pump performance to maintain the configured operating conditions.

Motor frequency is controlled using PID speed control in pressure, flow and temperature modes, or proportional speed control in level mode. To eliminate high starting currents and minimize pipeline water hammer, the control panel executes staggered pump starting and stopping sequences. Run hours are balanced across all available drives through built-in duty alternation and automatic sharing protocols.

A 7-inch touchscreen HMI and Setup Wizard 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.
