Product Description:
The FC-202N400T7134H1815 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. Belonging to the VLT AQUA Drive product group, the unit modulates induction motor speed so pumping stations, aerators, and filtration skids can match flow demand without mechanical throttling. In industrial automation, it sits between the three-phase supply and the motor, providing closed-loop control and electrical protection in demanding water and wastewater environments.
The drive handles three-phase power supplies from 525–690 V AC, and its power electronics and cooling system support a continuous shaft output of 400 kW. Internal braking circuitry can dissipate up to 32 kW during rapid deceleration, provided that a resistor of at least 2.3 Ω is connected with conductors sized to 70 mm² (3/0). The resistor must accommodate the resulting thermal load, while the conductors must safely carry the braking current. Compliance with EN/IEC 61800-3 Category 1/2 and the emission limits of EN 55011 Class A1/B is supported by the factory-installed RFI Class A1/B (C1) filter. The inverter supports motor balance by limiting phase-to-phase voltage deviation to 3.0 percent. Energy performance meets the IE2 efficiency class, helping reduce operating losses at high power levels.
For field installation at elevations up to 1,000 m above sea level, the unit delivers full power, and its control electronics tolerate ambient air temperatures up to 50 °C without derating. Grid resilience is supported by a prospective fault capacity of 100,000 RMS symmetrical A, while power quality is improved through a true input power factor of ≥0.9 and a displacement power factor of >0.98. The high fault capacity supports operation on robust industrial supply networks, and the power factor values help limit unnecessary transformer and distribution-system loading. These electrical characteristics make the drive suitable for high-power pumping systems connected to three-phase industrial grids.
