Product Description:

The FC-202P11KT2134F0184 is a variable-frequency drive manufactured by Danfoss for the VLT FC 202 AQUA Drives series. Designed for pump and fan duties in water treatment and irrigation plants, the unit modulates motor speed by adjusting the output frequency supplied to a standard induction motor. This functionality allows operators to match hydraulic performance to changing process conditions while lowering mechanical wear and electrical consumption in automated fluid-handling systems.

With a continuous output current of 46.2 A, the drive can deliver up to 15 HP for sustained operation of medium-sized centrifugal machines. Its apparent power capability is rated at 16.6 kVA, which is used to size upstream conductors and protective devices. The three-phase input supply must remain between 200 – 240 VAC, and the control section tolerates a mains phase imbalance of 3%. Output frequency is adjustable from 0 Hz up to 590 Hz, enabling oversynchronous operation when high impeller tip speeds are required. A single analog output retransmits process values. The digital outputs can switch up to 40 mA at 32 kHz for high-resolution status signaling.

The recommended upstream fuse is rated at 63 A, coordinating with the drive’s short-circuit withstand capability and limiting fault energy. Motor leads may run up to 150 m when shielded or 300 m when unshielded without exceeding output filter limits, providing flexibility in large pump rooms. Control terminals accept conductors ranging from 0.25 mm² to a maximum of 1.5 mm². The permitted power-up rate is one start per minute, which prevents thermal stress on the DC-link components. Proper separation of control and motor wiring can reduce interference in analog signals and other low-voltage circuits. Shielded motor cables can also help limit radiated electrical noise where the drive is installed near sensitive control equipment.
