Product Description:

The FC-202P11KT6131G1536 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. The unit conditions three-phase mains power and modulates motor speed for pumps, blowers, and other water-handling equipment. This speed control allows connected equipment to match process demand while reducing energy use in industrial automation.

It delivers a continuous output power of 11 kW, equivalent to 15 HP, allowing mid-range centrifugal or positive-displacement pumps to start and run without mechanical throttling. The input section is rated for a 600 V class supply and accepts three-phase power, so the drive can be wired directly to common 575 V industrial networks. Internal switching devices operate at a carrier frequency of 110 kHz; this high frequency improves current smoothing and audible noise performance. Overall conversion efficiency reaches 0.98, meaning only two percent of the electrical energy is lost as heat under nominal load. The control board provides one analog output with 8-bit resolution and supports 500 Ω loads, while a digital transistor output sources up to 40 mA for status relays or counter inputs. A 24 V auxiliary rail supplies 200 mA to external sensors, simplifying field wiring.

The inverter maintains full current at ambient temperatures up to 50 °C when airflow over the heat sink is unobstructed. Motor leads may extend to 150 m when shielded or 300 m when unshielded, providing flexibility for remote wet-well installations. The unit requires no output derating at elevations up to 1000 m. It can operate at elevations as high as 3000 m when programmed current reduction is applied. Upstream circuit protection uses a maximum pre-fuse rating of 40 A, allowing the drive to operate with suitable Class J or gG fuses. Proper airflow, cable selection, altitude settings, and upstream protection help maintain reliable operation within the stated limits.
