Product Description:

The FC-202P7K5T6131G1535 is a three-phase variable frequency drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. In automated installations, the drive converts fixed-frequency mains power into a controllable output that lets connected motors follow changing process requirements. It provides speed regulation, current limiting, and coordinated braking without the energy losses associated with mechanical throttling. This functionality is suitable for pumps and other motor-driven equipment that must adjust output in response to changes in flow, pressure, or demand.

The inverter delivers a shaft power rating of 7.5 kW, which is mechanically equivalent to 10 HP, while supplying a continuous output current of 11.5 A. Its control section can raise the output frequency to 590 Hz, so high-pole or specialized pump motors can operate above base speed when needed. The electrical efficiency is 0.97, allowing most of the input energy to reach the load while minimizing heat accumulation in the cabinet. The drive provides 11.0 kVA of continuous apparent power at 550 V and accepts a maximum input current of 10.4 A. Its thermal relay setting is 2.3 A for coordinating external motor protection. The power stage operates on a three-phase supply and supports motor cables up to 300 m when unshielded or 150 m when shielded without exceeding the permitted waveform limits.

The unit can operate at ambient temperatures up to 50 °C before derating is required. Dynamic braking energy can be routed to an external resistor bank rated to dissipate 0.570 kW, while the estimated internal power loss during nominal operation is 261 W. The braking circuit permits a minimum resistance of 99.0 Ω. Its nominal resistance is 121.1 Ω, and the recommended resistance is 100 Ω to balance energy absorption with resistor heating. A 32 A upstream fuse provides supply-side protection by interrupting fault current before it can damage the power stage.
