Built to respond when stormwater levels change, the MATelec HydroTOUCH FPC-43420-D manages four 3 kW pumps from a 4-20 mA level signal. 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.
To maintain system efficiency, this panel incorporates advanced PID control parameters that adjust pump speed in response to system feedback. To eliminate high starting currents and minimize pipeline water hammer, the control panel executes staggered pump starting and stopping sequences. Built-in duty sharing and alternation protocols balance operating hours across all connected pumps to extend equipment service life.
A 7-inch touchscreen HMI hosts a Setup Wizard to simplify system commissioning. Users can monitor real-time power and water usage graphs, historical trend plots, and system event logs directly from the screen.
Din rail mounted terminals are provided for dual 4–20 mA inputs for level, pressure or temperature transducers, plus up to five 24 Vdc digital inputs. 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.
