Product Description:

The FC-202P30KT4E55H2XGC is an AC variable-frequency drive built by Danfoss for the VLT FC 202 AQUA Drives series. In pump and blower installations, it modulates motor speed to match real-time flow or pressure demands, improving energy use in water and wastewater plants and irrigation systems. The drive converts fixed mains input into programmable motor output that can coordinate with PLC sequences and process instrumentation. Its control functions are intended for variable-torque loads commonly found in fluid-handling systems. Scalar and vector control modes help maintain constant pressure while reducing the hydraulic shock associated with abrupt changes in pump speed.

Rated for a continuous output of 30 kW, the unit is suitable for midsized centrifugal pumps and similar motor-driven equipment. The input section accepts 380–480 VAC and operates with a three-phase power supply commonly available in industrial switch rooms. This input range allows the drive to operate on several standard industrial supply voltages without an additional transformer. The IP55 / Type 12 enclosure protects internal components from dust and low-pressure water jets, allowing installation in demanding indoor locations without a separate protective cabinet. Its enclosed design also supports placement near pumping equipment when the installation provides the required ventilation and mounting clearances.

An integrated RFI filter attenuates conducted electrical noise on the supply lines, helping reduce interference with nearby control and communication equipment. A coated printed circuit board protects circuit traces from condensation and airborne chemicals, supporting operation in humid pump rooms and treatment-plant galleries. Local setup and monitoring are performed through the graphical local control panel, which provides access to parameter adjustments, operating values, and trend information without external tools. Emergency shutdown functions use safe torque off rather than dynamic braking. The drive has no brake chopper, which simplifies wiring in systems where mechanical check valves or other external devices already control backflow and rotating loads. Proper system design must still account for motor coast-down behavior and any process conditions that could continue driving the pump after power is removed.
