MATelec HydroTOUCH FPC-43220-I Mild Steel 15 kW Variable Speed Dual Pump Controller

Dosing applications that use twin pumps can rely on the MATelec HydroTOUCH FPC-43220-I for 15 kW variable-speed control and Modbus RTU RS485 communications. Operating on a three-phase power supply of 400 Vac at 50 Hz, this controller manages dual-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. Staggered pump starting and stopping sequences are programmatically executed to prevent electrical current surges and mechanical water hammer. 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.
