MATelec HydroTOUCH FPC-43320-J Mild Steel Three Phase 18.5 kW Variable Speed Triplex Pump Controller

The MATelec HydroTOUCH FPC-43320-J keeps triplex hot water recirculation responsive at 18.5 kW, using a 4-20 mA level transducer to follow system conditions. This panel manages the operation of triplex-pump configurations using a three-phase power supply of 400 Vac at 50 Hz. Connected instrumentation feedback allows the control module to adjust VSD frequency dynamically, ensuring efficient water management.

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. Built-in duty sharing and alternation protocols balance operating hours across all connected pumps to extend equipment service life.

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.
