R3G310-AN12-30/F01 ebmpapst 48VDC EC Centrifugal Fan

Description

The ebmpapst R3G310-AN12-30/F01 is a high-performance 48VDC EC Centrifugal Fan unit featuring 6 backward-curved aluminium sheet blades with an Impeller Size of 310 mm and overall Dimensions of 318 x 119.5 mm. Specifically engineered for mission-critical telecommunications cooling, outdoor enclosures, and industrial DC-powered ventilation, this unit is driven by the M3G084-FA brushless EC external rotor motor with maintenance-free ball bearings. Operating on a 48 VDC supply (voltage range 36 – 57 VDC), it delivers a Power Input of 190 W and a Current Draw of 4.0 A at a rated speed of 2000 RPM under running at free air (rfa) conditions. Featuring a rugged black coated rotor surface and IP42 protection, it supports seamless speed control via 0-10V DC or PWM interfaces with integrated soft start and motor current limiting, ensuring superior thermal management and an extended service life in continuous S1 environments at the end.
