This controller operates on a standard three-phase power supply of 400 Vac at 50 Hz, adjusting VSD speed based on live transducer inputs. Based on real-time sensor feedback, the system adjusts pump performance to maintain the configured operating conditions.\u003c\/p\u003e\n\u003cp\u003eMotor frequency is controlled using PID speed control in pressure, flow and temperature modes, or proportional speed control in level mode. The controller adjusts the connected pump speed in response to system feedback to support stable operation.\u003c\/p\u003e\n\u003cp\u003eAn integrated Setup Wizard on the 7-inch touchscreen HMI simplifies system commissioning. Users can monitor real-time power and water usage graphs, historical trend plots, and system event logs directly from the screen.\u003c\/p\u003e\n\u003cp\u003eStandard 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.\u003c\/p\u003e\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eHoused in an IP44-rated, powder-coated mild steel enclosure with integrated ventilation\u003c\/li\u003e\n\u003cli\u003eMaintains constant pressure or flow rate using dynamic PID adjustment loops\u003c\/li\u003e\n\u003cli\u003eFeatures a pad-lockable mains power isolator switch for electrical safety\u003c\/li\u003e\n\u003cli\u003eSupports Modbus RTU RS485 SCADA protocols for remote monitoring and diagnostics\u003c\/li\u003e\n\u003cli\u003eProvides variable speed operation to adjust the connected pump in response to system demand\u003c\/li\u003e\n\u003cli\u003eIntegrated Setup Wizard on 7-inch color touchscreen HMI simplifies system commissioning\u003c\/li\u003e\n\u003cli\u003eEquipped with a dedicated Variable Speed Drive per pump for high-precision frequency control\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Matelec","offers":[{"title":"Default Title","offer_id":51095968514295,"sku":"FPC-43120-J","price":10699.21,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/matelec-hydrotouch-fpc-43120-j-variable-speed-single-pump-controller.png?v=1788256609","url":"https:\/\/foundationpumps.com.au\/products\/matelec-hydrotouch-fpc-43120-j-variable-speed-single-pump-controller","provider":"Foundation Pumps","version":"1.0","type":"link"}
