Product Description:

The FC-202P1K1T6131G5117 is a variable frequency drive built by Danfoss for the VLT FC 202 AQUA Drives series, part of the VLT AQUA Drive product group. Intended for centrifugal pumps and fans in water distribution, wastewater plants, and irrigation loops, the unit converts fixed-frequency three-phase power into a pulse-width-modulated output whose frequency follows process demands. By adjusting motor speed instead of throttling flow mechanically, the drive reduces energy consumption and maintains constant pressure across typical installations.

Electrical capability centers on a continuous power output of 1.1 kW, supplied from three-phase mains and protected by a 10 A upstream fuse. The converter draws no more than 2.4 A at rated load and reaches an internal efficiency of 0.97, resulting in only 50 W of heat loss. For smooth torque and reduced acoustic noise, it can switch at frequencies up to 32 kHz. Full performance is sustained at ambient temperatures as high as 50 °C. Motor leads with cross-sectional areas up to 4 mm² are accepted, and shielded runs can extend to 150 m without exceeding EMC or voltage-drop limits. The drive can connect directly to small induction pump motors. Its vector control algorithms keep flow stable under varying head pressure.

Control and feedback functions support common process instrumentation. Each analog output provides a 0/4–20 mA signal to loads up to 500 Ω, while digital outputs can sink up to 40 mA for relay or counter inputs. The microcontroller executes its control loops every 5 ms, enabling rapid pressure corrections and soft-fill routines. The drive meets the IE2 efficiency class requirements and supports a motor output of 1.5 HP. Input channels have a resistance of 4 kΩ. Terminal identifiers follow the series conventions to support straightforward wiring and connection checks during installation.
