Product Description:

The FC-202P75KT4E20H2XGXXXXSXXXXAXBXCXXXDX is an AC variable frequency drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. It converts fixed-frequency mains power into a variable-frequency output that allows plant control systems to regulate centrifugal pumps and aeration blowers used in water and wastewater processing. Matching motor speed to real-time flow demand can reduce energy consumption during periods when full pump output is unnecessary. Controlled acceleration and deceleration also reduce hydraulic shock in pipeline networks, helping limit pressure surges during routine changes in flow. The drive supports continuous speed adjustment in fluid-handling systems that operate under changing process demands.

The drive accepts three-phase power at 380–480 VAC, allowing direct connection to common industrial power systems within that voltage range. Its IP20 chassis protects against accidental finger contact with hazardous internal parts, but the unit requires installation inside a suitable ventilated enclosure. An internal RFI filter attenuates conducted electrical noise that could otherwise travel through the mains connection and interfere with nearby equipment. Local configuration and status monitoring are performed through the Graphical Local Control Panel, which presents operating values, alarms, and adjustable parameters through a visual menu. This interface provides direct access to pump-control functions without requiring a separate display device. Proper cabinet airflow must be maintained around the chassis to remove heat generated during continuous operation.

Power and control wiring enter through standard cable entries, providing conventional routing points for conductors inside the enclosure. The power stage has no brake chopper, making the drive appropriate for pump applications that do not require rapid dissipation of regenerated braking energy. Controlled deceleration should therefore be set according to the inertia of the connected pump and motor assembly. The unit uses an uncoated PCB, so it should be installed in a dry, non-condensing location that is protected from corrosive gases and conductive contaminants. A Standard Language Pack supplies the parameter and operating text shown on the control panel. Cable separation and grounding should follow applicable installation practices to reduce electromagnetic interference between power wiring, motor leads, and low-voltage control circuits.
