Product Description:

The FC-301PK37T4134L2184 is a variable frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. It is intended for three-phase machines used in conveyors, pumps, fans, and other automated equipment. The drive varies motor voltage and frequency so connected machinery can track process demand and reduce unnecessary mechanical wear. Its adjustable output also supports controlled acceleration and deceleration, which can reduce abrupt loading on motors, couplings, and driven components.

This drive provides 0.37 kW (0.50 HP) of continuous electrical power. The power stage accepts three-phase mains between 380 to 480 VAC and can deliver up to 1.3 A at 380 to 440 V to the motor terminals. Using pulse-width modulation, it produces an adjustable output from 0 to 590 Hz, while flux mode allows the motor to operate between 0 and 300 Hz. Control wiring includes 0 to 24 V DC digital inputs and an analog channel for 0/4 to 20 mA signals, allowing direct connection to PLC references. The output voltage ranges from 0% to 100% of the supply voltage. An internal clock maintains phase orientation when the incoming line voltage remains within the permitted ±10% range.

At rated load, the converter draws 1.2 A from the line, corresponding to an apparent power of 0.9 kVA at 400 V. Internal losses are limited to 35 W, resulting in an overall efficiency of 0.93. When connected to a mains supply operating at 50/60 Hz ±5%, the control logic compensates automatically to keep the synthesized carrier synchronized with the source. Thermal energy is routed through the aluminum baseplate, and the modest internal losses can permit installation without dedicated fan cooling when adequate airflow is available. Diagnostic menus display real-time operating measurements for checking current balance and confirming that the drive follows the commanded speed profile.
