Product Description:
The FC-202PK37T4134F0072 is an AC variable frequency drive manufactured by Danfoss and supplied under the VLT FC 202 AQUA Drives series. As a member of the VLT AQUA Drive product group, it serves pumping and aeration applications in automated water and wastewater systems. By converting fixed-frequency, three-phase line power into a regulated output, the unit allows PLCs and SCADA controllers to adjust motor speed precisely, minimizing hydraulic shock, lowering energy consumption, and extending mechanical service life in continuous-flow installations.
The drive connects to a three-phase supply of 380–480 VAC and can draw up to 1.0 A while delivering 1.2 A of continuous motor current. Apparent power reaches 0.9 kVA when the drive operates on a 460 V network, providing a mechanical output of 0.50 HP to the load. With an efficiency of 0.93, only 35 W is dissipated internally as heat, helping the cabinet remain within its thermal limits. The electronics are protected by a 10 A upstream fuse and can operate at ambient temperatures up to 50 °C without derating. The power conversion stage uses three-phase power and helps limit harmonic distortion that could interfere with sensitive process sensors. This arrangement supports continuous operation with small motors used for controlled pumping and fluid-handling tasks.
The digital outputs have a maximum switching frequency of 32 kHz and can source up to 40 mA per channel for connected status circuits. Each analog output can drive instrumentation with load impedances as low as 500 Ω. Motor, line, and brake terminals accept conductors up to 4 mm², providing sufficient capacity for the associated field wiring. Shielded motor cables may extend up to 150 m, while unshielded cables may reach 300 m before additional output filters are required. The inverter provides a constant-torque power rating of 0.37 kW, making it suitable for small induction motors in chemical dosing systems, sampling pumps, and low-flow booster skids. Proper cable selection helps preserve motor performance and signal quality across the permitted connection distances.
