Product Description:

The FC-301P15KT2131B6047 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. It converts three-phase mains into a modulated output so automation controllers can adjust induction-motor speed and torque. In factory settings the unit handles pumping, conveying, or general motion tasks that benefit from electronic speed regulation and reduced mechanical wear.

The input section accepts a line of 200–240 VAC, and the power stage is sized for 74.8 A of continuous motor current, which equates to a shaft rating of 20 HP or 15 kW. Under nominal conditions the converter reaches a drive efficiency of 0.96, limiting waste heat even when cabinets are densely packed. When temporary load spikes occur it follows the high-overload profile of 150%/1 min/10 min, delivering short bursts of torque before returning to steady-state. Shielded motor leads can run up to 50 m without derating, allowing installations in large machines while keeping electromagnetic interference within limits. Normal input demand is 68 A, and the 24 V control supply can source 200 mA for sensors or relays.

During startup currents can rise to 54 A on the supply side, so upstream protection must accommodate this inrush. At nominal load the thermal dissipation measures 737 W; forced-air cooling is therefore advisable in compact panels, especially because the drive is specified for full output in ambient temperatures up to 45 °C. For heavier duty cycles an alternative mode supplies 59.4 A of motor current while the high-load power loss climbs to 624 W. Normal-overload support permits 110% torque for one minute every ten, and unshielded cable runs may extend to 75 m where EMC rules allow. All ratings fall under the VLT AutomationDrive FC product group and carry the internal series identifier 301.
