MATelec HydroTOUCH FPC-43420-A Mild Steel Three Phase 0.75 kW Variable Speed Quad Pump Controller

For water transfer spread across four pumps, the MATelec HydroTOUCH FPC-43420-A provides 0.75 kW variable-speed control informed by two transducer inputs. This panel manages the operation of quad-pump configurations using a three-phase power supply of 400 Vac at 50 Hz. The unit maintains consistent flow, pressure, or level based on real-time feedback from connected analog transducers and digital switches.

Motor frequency is controlled using PID speed control in pressure, flow and temperature modes, or proportional speed control in level mode. Staggered pump starting and stopping sequences are programmatically executed to prevent electrical current surges and mechanical water hammer. Run hours are balanced across all available drives through built-in duty alternation and automatic sharing protocols.

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.
