350W AC-DC PSUs Suit Industrial & Healthcare Apps

Compact chassis-mount 350W AC-DC PSUs offer easy integration


Intended for a wide range of equipment in industrial, technology and healthcare applications, XP Power’s new rugged AC-DC chassis-mount power supply units deliver up to 350W of power.

The SMP350 series is very competitively priced and targets a wide range of applications including automation and process control, broadcast, instrumentation and the energy and utilities sector, as well as offering versions suitable for use in medical equipment that offer reduced earth leakage current of less than 300μA.

The PSUs incorporate built-in fan cooling, screw terminal connections for simple installation and low EMI emissions, offering easy integration into end equipment, reducing design and manufacturing costs and time to market, according to the firm.


The units are offered in a 3.6 x 7 x 1.7-inch enclosure, and deliver power densities up to 13W/in3 enabling a compact, highly efficient and low-noise solution.

Other key features include a universal 85 to 264V AC input voltage range for use worldwide and a range of different models with 12, 15, 18, 24, 28, 36 and 48V DC outputs.

The PSUs feature an operating temperature range of –40 to +70°C and full power to +50°C, to meet the vast majority of industrial applications.

The series also features class-B EMI emissions compliance and remote on/off capability to simplify system control.

The products also boast a high efficiency resulting in less heat being generated and extended lifetimes; low no-load input power, resulting in reduced power consumption in standby mode; and input to output isolation of 4000V AC with a 2 x MOPP rating.

The SMP350 series is available from Digi-Key, element14, Farnell, RS Components, approved regional distributors, or direct from XP Power and come with a 3-year warranty.
