Product Description:

The FC302PK75T2131X7349H2BGXX is an AC variable frequency drive manufactured by Danfoss for the VLT FC 302 Automation Drives series. In automation systems, it converts fixed-frequency three-phase mains power into a regulated output that allows controllers to vary induction motor speed and torque. This control can reduce energy use in pumps, fans, and conveyors while maintaining process accuracy under changing operating conditions.

This model delivers 0.75 kW of continuous mechanical power from an electrical load of 1.83 kVA at 230 V. The input section draws a steady 4.10 A, and the inverter can supply 4.60 A to the motor terminals without derating. For short acceleration bursts, the rectifier tolerates 6.56 A, and overall efficiency remains 0.95 at rated current, so only 54 W of heat must be removed. The design limits power cycling to two starts per minute to protect the charging capacitors. Analog feedback is delivered with 12-bit resolution, enabling incremental torque control, and two isolated digital outputs report status or alarms. Each digital channel can sink up to 40 mA, providing a direct interface with PLC input cards. These signal channels allow operating conditions to be monitored without requiring separate interface relays in standard control circuits.

Peak overload current on the motor side reaches 7.40 A, allowing brief torque surges without triggering faults. Vector algorithms track motor flux at frequencies up to 300 Hz, and carrier adjustment extends the maximum output frequency to 590 Hz for high-speed spindles. Installation permits a shielded motor cable length of 150 m or an unshielded motor cable length of 300 m, providing flexibility when routing conductors between the drive and motor. The permitted cable lengths accommodate both electrically sensitive installations and longer equipment layouts. Appropriate shielding and routing practices help limit electromagnetic interference while preserving reliable motor control over the installed cable run.
