Compact chassis-mount 350W AC-DC power supplies for easy integration
The SMP350 series incorporates built-in fan cooling, screw terminal connections for simple installation and low EMI emissions so that it can be easily integrated into end equipment, reducing design and manufacturing costs and time to market. Packaged in a 9.1 x 17.8 x 4.3mm (3.6 x 7 x 1.7in) enclosure, the series delivers power densities up to 13W/in3.
The series 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 series has a universal 85 to 264V AC input voltage range for use worldwide and offers a range of different models with 12, 15, 18, 24, 28, 36 and 48V DC outputs. With a wide 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.
Other key features include 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.
