Product Description:
The FC-202P37KT2134N5069 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. Within the VLT AQUA Drive product group, it functions as the speed-control element in water and wastewater automation, matching pump or fan output to real-time process demand. By converting constant mains power into a pulse-width-modulated output, the unit allows precise adjustment of induction motor torque, thereby cutting energy use and reducing mechanical stress on valves and impellers in municipal treatment plants, irrigation systems, and HVAC cooling towers.
Electrically, the drive is suitable for three-phase power supplies in the 200–240 VAC range, making it compatible with low-voltage distribution grids. Its input side can draw a continuous current of 130 A, which the power stage converts into an output capability of 143 A at the motor terminals. With a continuous apparent power rating of 51.5 kVA, the inverter accommodates high inrush conditions while maintaining a full-load efficiency of 0.97, minimizing heat losses in control cabinets. The internal design supports standard upstream protection with a maximum fuse rating of 200 A. It also accepts analog reference impedances down to 500 Ω and digital outputs up to 40 mA for field instrumentation.
Thermal and installation limits support operation from 0 °C up to a maximum ambient temperature of 50 °C, with full performance maintained at altitudes up to 1000 m and controlled derating permitted up to 3000 m. The drive supplies 37 kW of mechanical output, equivalent to 50 HP, when paired with compatible induction motors. Carrier switching frequencies are adjustable up to 32 kHz, which can reduce audible motor noise in sensitive environments. Motor leads may extend to 150 m when shielded or 300 m when unshielded without exceeding rise-time guidelines. These cable lengths provide flexibility when positioning the drive at a practical distance from pumps or fans while helping maintain predictable motor insulation stress.
