Description：

The ebm-papst D3G146-AH50-16 is a centrifugal cooling fan and dual-inlet EC blower designed for cooling applications associated with industrial inverters and variable speed drives. Its configuration provides forced-air cooling for equipment where continuous airflow is required during operation.

The D3G146-AH50-16 operates from a 200–277 V power supply and supports both 50 Hz and 60 Hz frequencies. This specified voltage and frequency range allows the blower to operate within the stated electrical supply conditions of compatible industrial equipment.

The unit has a rated current draw of 1.2 A. Together with its specified operating voltage, this electrical characteristic defines the stated power requirements of the blower.

For rotational performance, the D3G146-AH50-16 operates at 1700 RPM. This operating speed supports the centrifugal airflow function required for cooling industrial inverter and variable-speed-drive equipment.
