By utilizing advanced motor control algorithms, this 3.0 kW (4.0 HP) unit optimizes fan and pump performance in commercial and industrial HVAC infrastructure, directly contributing to reduced energy consumption and lower operational overhead. Its robust design minimizes unscheduled maintenance cycles by providing precise speed regulation and soft-start capabilities, which protect mechanical components from the high-torque stresses associated with direct-line starting. This unit is a standard solution for facilities requiring reliable 380-480 VAC motor control in climate-controlled or protected technical environments.\u003c\/p\u003e\n\u003ch3\u003eTechnical Configuration\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003e131L9865\u003c\/strong\u003e follows the VLT HVAC Drive FC-101 naming convention. The \"P3K0\" code establishes a nominal power rating of 3.0 kW, suitable for medium-duty HVAC loads. The \"T4\" designation confirms compatibility with 380-480 VAC three-phase grids. Featuring an \"E20\" IP20-rated enclosure, the drive is designed for mounting within ventilated control cabinets. The \"H4\" suffix indicates an integrated RFI Class A1 (C2) filter, ensuring compliance with electromagnetic interference standards in commercial building environments. This model provides an efficient interface for building automation controllers, allowing for streamlined integration into complex HVAC control loops without the complexity of unnecessary advanced industrial features.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"1\"\u003e\u003cstrong\u003eFeature\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd data-row=\"1\"\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"2\"\u003eModel\u003c\/td\u003e\n\u003ctd data-row=\"2\"\u003e131L9865\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"3\"\u003eBrand\u003c\/td\u003e\n\u003ctd data-row=\"3\"\u003eDanfoss\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"4\"\u003eSeries\u003c\/td\u003e\n\u003ctd data-row=\"4\"\u003eVLT HVAC Drive FC-101\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"5\"\u003ePower Rating\u003c\/td\u003e\n\u003ctd data-row=\"5\"\u003e3.0 kW \/ 4.0 HP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"6\"\u003eMains Voltage\u003c\/td\u003e\n\u003ctd data-row=\"6\"\u003e380 - 480 VAC (3-phase)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"7\"\u003eEnclosure Class\u003c\/td\u003e\n\u003ctd data-row=\"7\"\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"8\"\u003eRFI Filter\u003c\/td\u003e\n\u003ctd data-row=\"8\"\u003eClass A1 (C2)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"9\"\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd data-row=\"9\"\u003e-10 to 45 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"10\"\u003eDimensions\u003c\/td\u003e\n\u003ctd data-row=\"10\"\u003eApprox. 29.2 cm x 13.0 cm x 20.0 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd data-row=\"11\"\u003eNet Weight\u003c\/td\u003e\n\u003ctd data-row=\"11\"\u003e3.6 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eFAQs\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIs the FC-101 suitable for water pumping applications?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, the FC-101 series is designed for HVAC and pumping.
