Product Description:

The FC-202PK75T4131B8886 is a variable frequency drive manufactured by Danfoss and supplied within the VLT FC 202 AQUA Drives series. Designed specifically for pump and fan control in water treatment, irrigation, and HVAC plants, the unit converts fixed mains frequency into a variable output that matches real-time flow requirements. By integrating with automated controllers, the drive enables accurate pressure regulation, lowers energy consumption, and extends the mechanical service life of centrifugal equipment used throughout industrial automation.

Rated at 0.75 kW, the inverter delivers a mechanical output of 1.0 HP to connected induction motors. It operates within a supply range of 380 – 480 VAC, drawing a continuous input current of 1.9 A and presenting an apparent power demand of 1.7 kVA at 460 V. The control section modulates the inverter bridge to sustain a continuous output current of 2.1 A while maintaining an efficiency of 0.96 under nominal load. An 8-bit analog output is available for process feedback and can drive loads down to 500 Ω. Separate digital outputs source up to 40 mA for alarms or relay drivers. Internal logic limits power cycles to two per minute so the inrush network can recharge fully between starts.

Thermal management is supported by a full-load power loss of 46 W, which helps determine enclosure ventilation needs. The PWM section can switch at frequencies up to 32 kHz, allowing acoustically optimized motor operation. Upstream protection uses a 10 A fuse on the three-phase feeder. Downstream connections accommodate 4 mm² motor leads and 6 mm² disconnect wiring. The drive operates with three-phase power, making it suitable for common industrial supply systems. Its parameters are organized under the VLT AQUA Drive product group with identifier 202, providing a consistent menu structure across the range.
