Product Description:

The FC-301P3K7T2131B1194 variable frequency drive is manufactured by Danfoss as part of the VLT FC 301 Automation Drives series. Within an automation cell, it converts fixed-frequency supply power into a controlled output waveform so that AC motors can match the process load without mechanical throttling. Its compact chassis mounts directly in IEC control panels and provides parameter access through the native keypad or optional fieldbus interfaces. This arrangement allows the drive to regulate motor speed and torque in conveyors, pumps, fans, and other automated machinery.

The drive accepts three-phase power across an input range of 200–240 VAC, and the supply current can reach 15 A at maximum demand. At 230 V, the converter handles 6.65 kVA of continuous apparent power and provides a motor output of 3.7 kW, which corresponds to 5.0 HP. Its continuous output current is 16.7 A, supporting compatible motors under sustained operating conditions. Two transistor digital outputs provide status or control signals, and each output is rated for a sink current of 40 mA. The voltage range accommodates typical 208 V branch circuits used in North American industrial facilities and supports installations with a shared DC bus. The control electronics limit automatic restarts to two power-up cycles per minute to protect the drive and connected machinery.

The drive operates with an efficiency of 0.96, while thermal dissipation is limited to 185 W under rated load. The displacement power factor remains above 0.98, and the true power factor stays at or above 0.9 to reduce reactive demand on the supply feeder. The inverter can generate magnetic flux at frequencies up to 300 Hz. Its carrier modulation supports a maximum output frequency of 590 Hz, allowing operation with high-speed spindles and pumps running above synchronous speed. Appropriate enclosure ventilation must accommodate the generated heat so the power electronics remain within their operating temperature range.
