MATelec HydroTOUCH FPC-43320-F Mild Steel Three Phase 5.5 kW Variable Speed Triplex Pump Controller

Constant-pressure installations can balance three 5.5 kW pumps with the MATelec HydroTOUCH FPC-43320-F while tracking water movement through a pulse flow meter. Operating on a three-phase power supply of 400 Vac at 50 Hz, this controller manages triplex-pump setups to ensure system parameters are met. 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 operation is programmed into the system to prevent electrical surges and reduce mechanical pipe shock during pump cycling. Operating hours are distributed evenly across the pump drives using integrated duty alternation and automatic sharing algorithms.

A 7-inch touchscreen HMI hosts a Setup Wizard to simplify system commissioning. The interface provides detailed system monitoring, including power usage graphs, trend plots for pressure or level, and logged alarm events.

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.
