Product Description:

The FC-202PK55T2134F6396 is an AC variable frequency drive manufactured by Danfoss within the VLT FC 202 AQUA Drives series. The unit functions as a pump and fan controller in automated water and wastewater processes, where it adjusts motor speed to match hydraulic demand and reduce energy consumption. Its three-phase power electronics generate a controlled output that helps centrifugal equipment maintain constant pressure or flow without relying on mechanical throttling. This speed regulation also allows the connected equipment to respond to changing process conditions while reducing unnecessary motor operation.

On the input side, the drive draws a continuous current of 3.2 A and has a 1.26 kVA requirement at 208 V. It converts the incoming power to a motor output rated at 3.5 A. The power stage accepts a three-phase line supply of 200 to 240 VAC, covering common low-voltage distribution systems used in industrial facilities. Its electrical output is rated at 0.55 kW, making the drive suitable for small pumps and fans within that shaft-load range. With a full-load efficiency of 0.95, the inverter meets the IE2 efficiency class and limits estimated internal heat dissipation to 42 W. A 10 A prefuse protects the input circuit against short-circuit faults and must be coordinated with the facility’s electrical protection system.

The drive can operate without derating at elevations up to 1000 m and at surrounding air temperatures as high as 50 °C. Ambient operation can begin at 0 °C, allowing installation in a range of indoor pumping stations and treatment systems. The enclosure accepts disconnect conductors up to 6 mm², or 10 AWG, and motor leads up to 4 mm², or 12 AWG. Shielded motor cable can extend to 150 m, while unshielded cable can extend to 300 m without exceeding the drive’s output-filtering limits. Cable type, conductor size, routing, and grounding must be selected to maintain electromagnetic compatibility and dependable motor operation across the permitted installation range.
