Product Description:

The FC-202PK75T4136H9364 is an AC variable frequency drive produced by Danfoss for the VLT FC 202 AQUA Drives series. In water and wastewater installations, it modulates the speed of induction motors that run pumps or blowers, matching flow demand and reducing energy use. By converting fixed-frequency three-phase mains power into a variable-frequency output, the unit supports closed-loop control that can be integrated into broader industrial automation systems.

The drive is designed for 380 – 480 VAC networks and is wired for three-phase power, so no phase conversion is required inside the panel. Its power stack is rated for 0.75 kW of continuous output, making it suitable for small centrifugal pumps and dosing skids. Under rated load, it reaches an efficiency rating of 0.96, limiting the amount of input power lost as heat. The continuous input current is 1.9 A, which indicates the current drawn from the supply during normal operation. The analog output can drive loads up to 500 Ω, while two programmable digital outputs can source 40 mA each for external control and status functions. The internal control scan interval updates parameters every 5 ms, supporting tight regulation of flow or pressure.

At maximum speed, the inverter dissipates 46 W, so natural convection is normally sufficient when the drive is mounted to a suitable panel surface. The power stage supplies 2.1 A of continuous output current across the 441–480 V range, allowing the connected motor to operate without exceeding the drive’s sustained current capacity. A maximum carrier frequency of 32 kHz provides flexibility when balancing audible motor noise against motor heating. Upstream circuit protection is provided by a 10 A fuse, which helps isolate the drive during an overcurrent condition. Motor conductors may have a cross-sectional area of up to 4 mm² to fit the available terminals and carry the required output current.
