MATelec HydroTOUCH FPC-43220-E Mild Steel 4 kW Variable Speed Dual Pump Controller

Pressure boosting becomes easier to manage with the MATelec HydroTOUCH FPC-43220-E, which controls two 4 kW pumps from a supplied 16 bar pressure transducer. This panel manages the operation of dual-pump configurations using a three-phase power supply of 400 Vac at 50 Hz. It monitors input signals continuously to adjust motor speed and maintain precise system parameters according to the user setpoint.

To maintain system efficiency, this panel incorporates advanced PID control parameters that adjust pump speed in response to system feedback. 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 and Setup Wizard 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.
