Product Description:
The FC-301PK37T4131Z7248 is a variable frequency drive manufactured by Danfoss as a member of the VLT FC 301 Automation Drives series. Designed for three-phase supply networks, the drive converts fixed line voltage into a pulse-width-modulated output so that control systems can match motor speed to process demand. In small-horsepower machinery, it provides closed-loop regulation, torque limiting, and energy savings while occupying minimal cabinet depth.
The drive has a power rating of 0.37 kW, which is equivalent to 0.50 HP. When connected to 380–480 V lines, the unit draws 1.2 A at 380–440 V or 1.0 A at 441–500 V, and it delivers 1.3 A and 1.2 A at the output for those respective voltage ranges. At rated load, the efficiency reaches 0.93, so only a small fraction of the input power is converted into heat. The input section accepts a three-phase supply of 380–480 VAC without derating, which supports operation on common industrial power systems. For discrete control, the front terminals provide 4 programmable digital inputs and two digital outputs, allowing start, stop, and interlock functions to be handled without additional relays. On a 400 V supply, the apparent power is 0.9 kVA, which is suitable for light-duty motors.
The signal interface also offers an analog output with 12-bit resolution for speed feedback or process indication. The digital outputs can switch at up to 32 kHz to operate compatible high-speed devices. Thermal management is supported by a maximum-load power loss of 35 W, allowing the drive to share an enclosure with other electronics when adequate airflow is provided. Shielded motor leads may run up to 50 m, while unshielded motor leads may run up to 75 m, providing flexibility when positioning the drive relative to the motor. The two programmable digital outputs can each supply up to 40 mA for connected control equipment.
