MATelec HydroTOUCH FPC-43420-K Mild Steel Three Phase 22 kW Variable Speed Quad Pump Controller

Completing the range, the MATelec HydroTOUCH FPC-43420-K coordinates four 22 kW pumps for chiller supply and monitors conditions through dual transducer inputs. This panel manages the operation of quad-pump configurations using a three-phase power supply of 400 Vac at 50 Hz. 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. Run hours are balanced across all available drives through built-in duty alternation and automatic sharing protocols.

A 7-inch touchscreen HMI and Setup Wizard simplify system commissioning. The diagnostic screens display graphical overview screens, power and water usage charts, and timestamped alarm logs for system maintenance.

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.
