AC/DC Switch Mode Power Supplies suit railway environments.

Press Release Summary:

AC/DC Switch Mode Power Supplies suit railway environments.

Jun 15, 2012 - Operating from 115 or 230 Vac input, POL 400R Series delivers 12, 24, 36, 48, or 110 Vdc with efficiency from 80-90%, depending on configuration. Units include 3,000 Vdc input/output isolation, overload protection, and current limiting. Housed in 131 x 66 x 232 mm enclosures, 400 W power supplies are conduction cooled and operate in -40 to +70°C cold plate temperature range. Units are fully encapsulated in thermally conductive MIL-grade silicon rubber compound for shock and vibration resistance.

400W AC/DC Power Supply Suits Railway and Other Extreme Environments

Press release date: May 30, 2012

ABSOPULSE Electronics introduces the POL 400R Series railway quality, ac/dc switch mode power supplies. The units meet relevant sections of EN50155 for electronic equipment used on railway rolling stock. They also comply with EN50121-3-2 and EN55022 Class B conducted and radiated EMI and applicable EN61000 standards, ensuring immunity to electromagnetic noise in the environment and minimum interference with other electronic equipment. In addition to a range of railway applications including signaling and communications, the units are suitable for operation in industrial, mining, military, marine and other severe environments.

These 400W power supplies operate from input sources of 115Vac (97-132Vac range) or 230Vac (195-264V) and deliver outputs of 12Vdc, 24Vdc, 36Vdc, 48Vdc or 110Vdc. Efficiency is between 80 and 90%, depending on the input/output configuration required. The POL 400R Series has comprehensive protection features including 3000Vdc input/output isolation, overload protection and current limiting. An optional output redundancy diode allows for parallel connection to achieve higher output power or N+1 redundancy. Other options include an output fail alarm and an LED adapter can be installed on the terminal block to indicate an output gONh condition.

The POL 400R units are conduction cooled and operate in a -40°C to +70°C cold plate temperature range for full specification - no fans are required. Housed in rugged, compact 131 x 66 x 232 mm enclosures, the power supplies are fully encapsulated in a thermally conductive MIL-grade silicon rubber compound, which protects against high levels of shock and vibration (EN61373/IEC61373), moisture, dust and other contaminants.

Standard versions of the POL 400R Series are priced in the C$360 range in quantities of 100.
