FC-202 Danfoss
Wake Industrial LLC is not an authorized distributor of this product.
The Danfoss FC-202 is part of the VLT FC 202 AQUA Drives series. It supports operation at altitudes up to 1000 meters without derating and features an ambient temperature range from 0 to 50 degrees Celsius at full load. The drive offers an open-loop speed error of plus or minus 8 RPM and a control response time of 2 milliseconds or less.
Internal Product Review
The FC-202 is a Danfoss VLT AQUA Drive with fast ≤2 ms control response and precise ±0.003 Hz output frequency resolution. Stable operation stands out through ±10% input voltage compensation and an open-loop speed error of only ±8 RPM. A strong choice for water and process systems, especially with IE2 energy efficiency.

Product Description:
The FC-202 variable frequency drive is manufactured by Danfoss and supplied in the VLT FC 202 AQUA Drives series. Intended for centrifugal pumps, blowers, and other water-handling equipment, it converts fixed-frequency three-phase mains power into a modulated output that lets automation systems match motor speed to process demand. By regulating frequency and voltage, the drive helps reduce energy use and mechanical wear in industrial liquid-distribution and treatment applications.
The unit handles ambient temperatures up to 50 °C at full rating and operates down to -10 °C with derating. It also supports full-load operation at 0 °C. Installations at an altitude of 1,000 m require no capacity adjustment, while higher sites require a planned power reduction. A control response time of ≤2 ms enables quick torque changes, and open-loop regulation maintains speed within ±8 rpm across a 1:100 range. Output frequency can be adjusted in increments of ±0.003 Hz, allowing precise flow control. The input stage withstands mains variations of ±10% without a loss of performance, maintaining stable operation when supply conditions fluctuate.
Protective timers guard against fault conditions. The drive can operate at its current limit for 60 s before corrective scaling occurs, and an overtemperature event enforces a 30 % power reduction rather than an abrupt stop. If serial communication is interrupted, shutdown can be delayed for up to 99 seconds to avoid unnecessary trips. Altitude capability extends to 3,000 m with proportional derating, making the drive suitable for elevated facilities. Motor wiring may extend to 150 m with shielded cable or 300 m with unshielded cable, providing flexibility for installations in remote pump rooms. The drive meets the IE2 efficiency classification for power drive systems.
