Product Description:
The FC-302P4K0T5ZH1XG is an AC variable-frequency drive produced by Danfoss for the VLT FC 302 Automation Drives series. It converts fixed three-phase mains power into a modulated output for controlling the speed and torque of an induction motor. Closed-loop control allows the drive to correct motor performance in response to changing process demands. The unit is intended for conveyors, pumps, and general motion systems that require accurate speed regulation.
This model delivers a continuous power output of 4.0 kW, which is mechanically equivalent to 5.0 HP. It accepts a three-phase supply ranging from 380–500 VAC. A maximum output frequency of 590 Hz supports oversynchronous motor operation when an application requires higher shaft speeds. The auxiliary 24 V terminal can supply up to 200 mA for sensors, encoders, or relays, while the digital inputs tolerate up to 28 V DC. Digital outputs are rated for 40 mA and can operate indicator lamps or interlocks. The brake chopper activates when the DC bus reaches 810 V DC, allowing regenerated energy to be diverted from the intermediate circuit. A separate overvoltage alarm activates at 855 V DC. Mains current imbalance must remain within 3.0%, and energization should be limited to two power-ups per minute to reduce inrush-related wear. The drive meets IE2 efficiency class requirements and maintains a true power factor of at least 0.9 under nominal load.
The drive can operate at ambient temperatures up to 45 °C without derating. Motor connections may use up to 150 m of shielded cable, allowing the motor to be installed away from the drive while helping contain high-frequency emissions. Installations that do not require shielding may use up to 300 m of unshielded cable. The control electronics monitor the intermediate circuit and issue an alarm when excessive voltage is detected. Supply supervision also detects unacceptable phase-current imbalance before prolonged thermal stress affects the power stage. Field wiring should account for the digital input voltage limit and the available auxiliary current when several external devices share the control supply. The recommended start-frequency limit should be observed in applications that cycle mains power rather than using normal run and stop commands.
