Product Description:
The FC-202P75KT6134F4379 is a variable frequency drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. It belongs to the VLT AQUA Drive product group, and the internal 202 series identifier places it in the line of controllers optimized for water and wastewater pumps. By converting fixed-frequency mains power into a regulated output, the unit allows centrifugal pump speed to be adjusted directly from the drive. This control method helps maintain the required flow and pressure without additional throttling hardware, which can reduce unnecessary mechanical restriction in the pumping system.
This controller is designed for three-phase power networks and reaches a full-load efficiency of 0.98, limiting estimated heat loss to 1500 W. Under high-overload duty, the inverter can continuously supply 83 A, matching a shaft power of 55 kW. Normal-duty operation raises the continuous current to 100 A for 75 kW applications. The corresponding line current is 75 A at 575 V in high-overload mode and 91 A during normal-duty operation. Upstream protection may use a 225 A prefuse, while shielded motor cables can extend up to 150 m without exceeding the drive output limits. The drive tolerates a maximum ambient temperature of 50 °C, so additional cabinet airflow or output derating is required only when the surrounding temperature exceeds this limit.
Short-term demands are supported by a peak high-overload current of 125 A, while normal-duty transients are limited to 110 A. Each surge is time-limited by the drive’s thermal protection model to prevent excessive stress on the power stage and connected motor. Apparent power reaches 82.7 kVA during high-overload operation and 99.6 kVA in the normal-duty profile, providing useful values for transformer selection and cable ampacity calculations. The high-overload profile supports applications that experience greater torque demand during acceleration or changing hydraulic conditions. The normal-duty profile is suited to pump systems with smoother load characteristics and a higher continuous power requirement. These operating modes allow the drive to regulate submersible or surface-mounted pump motors connected to constant 575 V industrial feeders.
