Product Description:

The FC-202N450T4135U2463 is an AC drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. Intended for pumps and fans in water-handling systems, it modulates motor speed to match demand, lowering both energy use and hydraulic shock. The product accepts three-phase power and acts as the final control element that converts automation commands into variable voltage and frequency for the motor. This makes it suitable for applications where flow or pressure must respond smoothly to changing process conditions.

Supply flexibility starts with a window of 380 - 480 VAC and an input tolerance of ±10%, allowing stable operation on fluctuating industrial grids. The internal processor refreshes every 5 ms, so loop corrections remain timely during changing load conditions. One analog output provides 8-bit resolution and supports loads down to 500 Ω, and this channel can drive external indicators or actuators without buffering. Digital inputs present a 4 kΩ impedance for straightforward PLC coupling. For deceleration, the braking stage can absorb 42.000 kW at 10% duty when paired with an external resistor no smaller than 1.1 Ω. Wiring to the resistor uses a 2 × 50 mm² cable, and the architecture includes one analog channel, pulse outputs, and AQUA-specific control features.

High-resolution speed feedback is handled by a pulse encoder channel that switches at up to 32 kHz and sources 40 mA to isolated counters. Internal regulation relies on 4 independent PID controllers, reducing the need for auxiliary logic in many pump skids. Thermal safeguarding comes from a relay rated at 196 A, which trips the inverter before semiconductor limits are exceeded. These functions support stable control in water treatment, irrigation, and similar fluid-handling installations. The control structure can also reduce the amount of separate external logic needed in compact panels.
