The PACSR series are encapsulated board-mounted AC/DC converters. These ultra compact units which are 20% smaller than the size of competitor parts; also offer efficiencies of up to 94%. These modules can be used in outdoor power systems, addressing the need for fan-less applications in the industrial, COTS, signage and communications markets.

The PACSR series has two output power levels, 300W and 500W. They operate at universal AC input voltage from 85~264VAC, and have four output voltages of 12V, 24V, 28V, and 48V available, all with voltage trimming function. The standard features of the PACSR series include over temperature protection, input under voltage protection, and output over current and over voltage protection.

All modules in the PACSR series are packaged in an enclosed case and potted with thermal potting material, which ensures good thermal performance and high reliability in harsh environment applications. Power modules are able to operating in a wide baseplate temperature range of -40C to 100C. An optional heat sink is also available for extreme thermal requirements.

The AC/DC brick converter has many advantages compare to traditional AC/DC power supply module. The first being that the size of the PACSR module is much smaller compared to the conventional AC power supply. The fan-less operation also greatly improves the reliability of the power supply. By using the PACSR series the time engineers spend in the development cycle can also be greatly reduced in new project developments.
