AC/DC convection cooled sealed power supplies for harsh environments

Bel Power Solutions has released the ABS400/MBS400 Series of convection cooled power supplies which are sealed and fully potted, providing IP66/67 ingress protection and fit 1U applications. These devices can be mounted for conduction or convection cooling and are rated at 300W in still air and 400W with conduction through the optional heat sink.

The ABS400 Series offers a wide universal AC input range of 90-264VAC, giving up to 400W of output power in a single output of 12, 24, 36, or 48VDC and are provided in a 3.27" x 8.34" x 1.65" (83mm x 212mm x 42mm) form factor giving 12 and 5VBS standby outputs and a full set of protection features. This series also provides control signals including Power Good (Power_OK), Remote On/Off (PS_ON), and Remote Sense (+RS). Ideal applications comprise video wall displays and entertainment lighting, industrial and process control, telecommunications, laboratory and test and measurement equipment, as well as Class II outdoor signage.

The MBS400 Series is developed and approved to comply with the newest medical equipment standards and are IEC/EN 60601-1 3rd Edition, 2x MoPP rated, and BF appliances compatible. They can be installed in contact with the thermo-conductive region of the system to transfer heat by conduction and are compatible with 4,000m altitude operation. Typical applications comprise ventilators, computed tomography imaging, ultrasound, dialysis, laboratory, and operating room devices, as well as cleanroom equipment.
