SMP350 Series

AC-DC Power Supplies

SMP350 Series

300 to 350W forced-air cooled chassis mount AC-DC power supplies with industrial electronics, ITE & medical (2 x MOPP) approvals

The SMP350 series provides a range of rugged, enclosed, 300 to 350W AC-DC power supplies with integral fan, screw terminal connections and a wide operating temperature range of -40°C to +70°C ideally suited to a wide range of industrial applications.

The SMP350 series features high efficiency and class B EMI emissions for ease of integration into the end application and offers remote On/Off to simplify system control. Packaged in a 7” x 3.6” x 1.7” enclosure the series offers power densities up to 13W/in³ providing a compact, high efficiency, low noise power solution.
