Product Description:

The FC-202P7K5T4131X6545 is an AC variable-frequency drive from Danfoss built for the VLT FC 202 AQUA Drives series. It is used in industrial automation as a speed regulator for centrifugal pumps and fans, allowing supervisory controllers to adjust motor speed to match the hydraulic load instead of relying on throttling valves or dampers. By acting as the electrical interface between plant control signals and the motor windings, the drive maintains process flow, limits water hammer, and reduces overall energy consumption in fluid-handling systems.

This model delivers a mechanical output of 10 HP, which corresponds to an electrical power rating of 7.5 kW. Internally, the inverter section is rated for a continuous apparent power of 11.6 kVA, so it can supply the necessary current without derating when the load approaches its torque peak. The unit accepts three-phase mains between 380–480 VAC, eliminating the need for transformers in most low-voltage installations. Overall efficiency reaches 0.97 at nominal load, minimizing heat generation and lowering ventilation requirements inside control rooms. Two analog inputs with 0.5% full-scale accuracy receive pressure or level references, while a single analog output with 0.8% accuracy returns real-time motor feedback to external data loggers.

Operation is permitted at ambient temperatures up to 50 °C, after which external cooling or drive derating becomes necessary. Line protection is provided by a maximum upstream fuse rating of 30 A, coordinating the drive’s semiconductor ratings with upstream switchgear. The digital output can switch at frequencies up to 32 kHz for rapid status signaling to PLC inputs. Shielded motor leads may run up to 150 m without exceeding electromagnetic emission thresholds. The drive also carries the IE2 energy-efficiency classification for use in pump systems that follow this efficiency class.
