Product Description:
The FC-202N355T4135U2915 is a variable frequency drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. It is used in pump and fan stations where closed-loop speed control reduces water hammer, optimizes energy consumption, and protects pipework from abrupt pressure changes. The drive processes sensor feedback, controls IGBT switching, and supplies regulated three-phase power to a motor used in demanding municipal and industrial water-handling systems.
This model belongs to the VLT AQUA Drive product group and accepts a three-phase supply of 380 - 480 VAC. Under these conditions, it can deliver 355 kW of motor output for large centrifugal pump applications. The carrier frequency can be raised to 32 kHz when lower audible motor noise is required, although the resulting increase in switching losses must be considered. Overcurrent is monitored by an internal thermal relay with a trip setting of 157 A. The drive provides one analog output for process signaling, and this output can support a load impedance of up to 500 Ω. Its control and power sections are designed for operation with large pumps connected to three-phase mains power.
The drive supports continuous operation at ambient temperatures up to 50 °C and elevations up to 1000 m without power derating. It also tolerates relative humidity levels up to 95% when condensation is not present. The digital outputs can operate external relays or indicators at currents up to 40 mA. During high-inertia deceleration, the brake channel can dissipate 32 kW through external resistors connected by 2 × 35 mm² cables. The minimum braking resistance is 1.2 Ω, while the nominal value is 1.6 Ω and the recommended value is 1.3 Ω. These resistors absorb regenerated energy during controlled pump stops, helping the power stage prevent excessive DC-bus voltage while the motor slows.
