Product Description:
The FC-202N315T4134G8374 is a variable frequency drive produced by Danfoss for the VLT FC 202 AQUA Drives series within the VLT AQUA Drive product group. It is engineered to regulate the speed of centrifugal pumps, blowers, and related water-handling equipment in municipal and industrial automation systems. By converting fixed-frequency utility power into an adjustable three-phase output, the unit helps match motor torque to hydraulic demand, reducing energy consumption and mechanical stress on piping systems. The 202 platform provides fluid-control functions such as cascade control, dry-run detection, and soft-fill start sequences.
The drive delivers a maximum motor shaft output of 315 kW, permitting direct connection to high-capacity submersible or horizontal split-case pumps. Its input section accepts 380–480 VAC utility power and operates with three-phase power, so no external phase conversion is required. A front-mounted graphical local control panel presents real-time flow references, alarm history, and parameter groups through plain-text navigation, simplifying setup and operation. Overcurrent protection relies on a thermal relay calibrated to 124 A, which disconnects the inverter when prolonged thermal stress is detected. These electrical characteristics support operation in large water-handling systems where motor speed must change in response to varying flow or pressure demands.
Dynamic deceleration and emergency stops are handled by the integrated brake chopper. It can dissipate up to 26 kW of regenerative power through external resistors with a minimum resistance of 1.2 Ω. When sized for the specified 10% duty cycle, the braking network prevents DC-link overvoltage during repeated ramp-down events that occur in variable-level basins. Power is routed to the resistor bank through two 35 mm² conductors, maintaining an acceptable temperature rise during peak discharge. The external resistor arrangement allows regenerated motor energy to be converted into heat instead of accumulating on the DC link. This braking method supports controlled deceleration when pump inertia would otherwise keep the motor rotating after the output frequency begins to decrease.
