Product Description:
The FC-301PK37T2134L2930 variable frequency drive is produced by Danfoss for the VLT FC 301 Automation Drives series. Within the VLT AutomationDrive FC product group, it converts incoming three-phase mains power into a regulated output that allows a controller to vary induction motor speed in automated plant equipment. The device is intended for compact machinery that requires integrated motor protection and operates on a 200 V class distribution system. Its regulated output supports controlled acceleration, deceleration, and continuous speed adjustment in conveyors, pumps, fans, and other motor-driven equipment.
The input section accepts a nominal range of 200–240 VAC and feeds a DC link sized to deliver 0.37 kW of continuous motor power. The inverter can provide an output frequency of up to 590 Hz, while its flux mode supports a ceiling of 300 Hz for extended constant-torque operation. The control terminals have an input impedance of 4 kΩ, which helps prevent excessive loading on connected PLC sourcing cards. Digital lines tolerate up to 28 V DC, allowing them to work with common industrial control signals. High-resolution velocity commands can be transmitted through a pulse train input that operates at up to 110 kHz. These electrical characteristics support accurate speed commands and responsive motor control during changing process conditions.
Installation permits shielded motor leads up to 50 m long, while unshielded motor leads may extend to 75 m. The displacement power factor remains above 0.98, and the true power factor is at least 0.9, helping limit unnecessary mains current. Phase imbalance must remain below 3.0% to maintain stable input conditions and avoid uneven loading of the rectifier stage. The control terminals accommodate conductors with a cross-sectional area of 1.5 mm², providing suitable capacity for low-voltage command and feedback wiring. Power cycling is limited to two startups per minute to reduce inrush stress on the input components and DC-link capacitors. Overvoltage category III insulation permits connection in applicable low-voltage distribution zones. The mains connection must remain within the rated three-phase network so the drive can maintain its intended power quality and operating performance.
