A3G400-BK13-P1 ebmpapst 110VDC 400mm EC Axial Fan

Description

The ebmpapst A3G400-BK13-P1 is a high-performance 110V DC EC Axial Fan featuring a 400 mm impeller diameter and powered by the advanced M3G084-DF motor. This unit is specifically engineered for demanding environments, operating on a nominal 110 VDC with a wide range of 77-138 VDC. It delivers a rated speed of 1670 RPM at maximum load, consuming 460 W with a current draw of 4.2 A. The fan features 5 blades made of PA plastic (UL94 V0) and a black-painted die-cast aluminum electronics housing. With an IP55 protection rating, H3 environmental protection class, and Class F insulation, the A3G400-BK13-P1 is optimized for S1 continuous duty in railway and heavy-duty industrial applications. It is fully equipped with modern control features including RS-485 MODBUS-RTU, 0-10V/PWM speed control, and comprehensive thermal and electrical protections.

Application
The ebmpapst A3G400-BK13-P1 is a specialized EC axial fan designed for mission-critical railway and transportation infrastructure, meeting stringent fire protection (EN 45545-2) and vibration (EN 61373) standards. Its 110V DC operation and RS-485 MODBUS-RTU interface allow for seamless integration into vehicle control systems for cooling traction inverters, brake resistors, and HVAC units. The PA plastic UL94 V0 blades and IP55/H3 rating provide exceptional resistance to moisture and fire hazards. With features like soft start and thermal overload protection, it is ideal for high-static pressure environments requiring precise speed regulation and high reliability in sub-zero or high-temperature ambient conditions.
