Product Description:
The FC-301PK37T2134L2961 is an AC variable frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. The controller regulates the speed of induction motors used in conveyors, pumps, and general process machinery. It is designed for three-phase power networks and uses the internal 301 series identifier. The drive converts fixed-frequency mains power into a variable-frequency output for closed-loop automation tasks, allowing connected motors to respond accurately to changing process commands and operating conditions.
The motor output is rated at 0.50 HP, which corresponds to a continuous electrical power rating of 0.37 kW at the motor terminals. The inverter accepts a line supply of 200–240 VAC and delivers up to 2.40 A of phase current while maintaining speed control at output frequencies up to 590 Hz. Under rated load, the front end draws 2.20 A, while the current input has a resistance of 200 Ω and the voltage input has a resistance of 10 kΩ. At 208 V, the apparent power requirement is 0.86 kVA. The drive can energize external control circuits through a 10 V reference that supplies up to 15 mA and a 24 V service output rated at 200 mA. Shielded motor cables may extend to 50 m, while unshielded motor cables may extend to 75 m.
At 230 V, the converter draws an apparent power of 0.96 kVA and dissipates 29 W at maximum load, so normal panel airflow is generally sufficient for heat removal. Its electrical efficiency is 0.94, which limits conversion losses during continuous-duty operation. The supply can tolerate a phase imbalance of up to 3.0% before protective shutdown, providing operating tolerance for uneven power distribution on lower-power feeders. Breakers and filters should be selected according to the stated input demand, while enclosure ventilation should account for the heat dissipated under maximum load.
