Description
The ebmpapst K3G500-PB24-03/F01 is a high-performance 400VAC three-phase EC Centrifugal Fan from the RadiPac series, featuring backward-curved impellers with a support bracket and specialized F01 firmware. Driven by a high-efficiency GreenTech EC motor with integrated electronics, this 500 mm impeller size module is specifically engineered for mission-critical Air Handling Units (AHU), large-scale data center cooling, and industrial ventilation. Operating on a nominal voltage range of 380 to 480 VAC, it delivers a Power Consumption of 4200 W and a Current Draw of 6.4 A at a rated speed of 2000 RPM, with a maximum load capacity of up to 4.5 kW. Featuring a sheet aluminum impeller, an integrated PI controller, and RS-485 MODBUS-RTU communication, it achieves a static efficiency of 69.6% (Efficiency grade N=73.7), ensuring superior energy savings and reliable continuous S1 operation at the end.
