Product Description:

The FC-301P15KT4134G1792 is an AC variable frequency drive produced by Danfoss within the VLT FC 301 Automation Drives series. It converts fixed-frequency three-phase mains power into a modulated output for speed regulation of induction motors used in conveyors, pumps, and other automated machinery. By allowing programmable acceleration, deceleration, and constant-torque operation, the drive serves as a compact power stage between the plant supply and motor load, delivering closed-loop control that reduces energy consumption and mechanical stress in industrial automation.

It accepts a mains range of 380–480 VAC, and the power section is configured for three-phase power, so it can be wired directly to standard industrial distribution panels. Under rated conditions, the inverter delivers a continuous output current of 32 A, translating to approximately 20 HP at the shaft when matched with a standard motor. The silicon losses are low, and efficiency reaches 0.98 at rated current, which minimizes heat buildup inside electrical enclosures. The drive has a power rating of 15 kW, enabling it to handle medium-duty processing equipment without oversized auxiliary components.

Transient events are addressed by an intermittent overload capacity of 51.2 A for short bursts, allowing the motor to overcome inertial loads without tripping protection. During steady operation, the unit dissipates only 379 W, so panel airflow can be calculated based on this predictable thermal output. Shielded motor leads may be routed up to 50 m, while unshielded leads may extend up to 75 m to accommodate remote installations. Additional provisions include a 29 A continuous input draw, a limit of one power-up per minute to protect the capacitors, 1.5 mm² control wiring, a 3% mains phase imbalance tolerance, and a 50 mA RMS STO input for connection to functional safety circuits.
