Product Description:
The FC-301P15KT2131B5827 is a variable frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. It converts fixed three-phase AC power into a pulse-width-modulated output that allows control systems to vary induction motor speed and torque. In automated conveyors, pump skids, and process equipment, the drive uses closed-loop control algorithms to maintain stable motor performance while reducing unnecessary energy consumption. Its adjustable output also supports controlled acceleration and deceleration, which can reduce mechanical stress on connected equipment during repeated operating cycles.
The input stage accepts 200–240 VAC three-phase mains at 50/60 Hz with a tolerance of ±5 percent. Within this input range, the converter provides 15 kW of output power, equivalent to 20 HP. Constant-torque operation is maintained at frequencies up to 300 Hz in flux mode, allowing the drive to regulate demanding motor loads over a broad speed range. A dynamic brake is supported through the DC link, which reaches 390 V DC during energy dissipation; the warning threshold is 405 V DC, and an overvoltage alarm occurs at 410 V DC. Brake operation follows a 300-second cycle with a 10 percent duty factor at 100 percent rated torque, while short overloads of 150 or 160 percent are permitted during the same active interval. The incoming supply may have a phase imbalance of up to 3 percent before output derating is required.
At the motor terminals, the inverter provides an adjustable voltage range of 0–100 percent of the supply voltage. Its output frequency extends to 590 Hz, supporting high-speed spindles as well as conventional pumps, conveyors, and process machinery. During normal operation, the true displacement power factor remains at 0.9 or higher, which limits reactive demand on the upstream transformer and associated power distribution equipment. Shielded motor cables may extend up to 50 meters without exceeding the stated electromagnetic interference limits. Unshielded motor cables may be as long as 75 meters, giving installations additional routing flexibility when shielding is not required. These cable limits help preserve acceptable output performance across longer connections between the drive and motor.
