MATelec HydroTOUCH FPC-43320-G Mild Steel Three Phase 7.5 kW Variable Speed Triplex Pump Controller

For triplex process water applications, the MATelec HydroTOUCH FPC-43320-G adjusts three 7.5 kW pumps in response to signals from dual transducer inputs. This panel manages the operation of triplex-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. To eliminate high starting currents and minimize pipeline water hammer, the control panel executes staggered pump starting and stopping sequences. 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.
