MATelec HydroTOUCH FPC-43320-A Mild Steel Three Phase 0.75 kW Variable Speed Triplex Pump Controller

Three-pump water transfer is made more manageable by the MATelec HydroTOUCH FPC-43320-A, which provides 0.75 kW variable-speed control and pulse flow monitoring. This controller operates on a standard three-phase power supply of 400 Vac at 50 Hz, adjusting VSD speed based on live transducer inputs. 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. 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.
