Product Description:

The FC-202P30KT4131Z2312 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. The unit modulates the voltage and frequency supplied to induction motors so pumps, blowers, and aerators in water-handling applications can match real-time process demand. By substituting electronic speed control for mechanical throttling, it integrates into automated skids and panels where energy savings and stable flow regulation are required.

The drive’s input section handles a three-phase supply of 380–480 V AC at 50/60 Hz, then converts it into a programmable output capable of delivering 30 kW, equivalent to 40 HP, to the motor terminals. Output frequency is fully adjustable from 0–590 Hz, while output voltage can be set from 0% to 100% of the mains voltage, permitting broad control of pump curves. Internal power electronics operate at an efficiency of 0.98, and the displacement power factor remains at or above 0.9, so upstream conductors carry little reactive current. Upstream protection is provided by a maximum line fuse of 80 A. Acceleration and deceleration ramps are programmable from 1 second to 3,600 seconds, allowing gradual speed changes that can reduce mechanical stress and pressure surges in connected piping. The product maintains the IE2 energy-efficiency classification for variable-speed equipment.

Full-load operation is supported from 0 °C to 50 °C without derating, allowing the drive to operate in common water-industry field enclosures. The installation altitude can reach 1,000 m before output-current limits apply. Motor leads may extend to 150 m when shielded or 300 m when unshielded, allowing placement in remote pump rooms while keeping reflected-wave voltage within safe margins. The drive carries the internal 202 identifier, and its parameter arrangement and keypad layout are consistent with other systems of a similar rating.
