250W Power Supply
The JPS250 Quad Series is a 250W power supply featuring four outputs. Full power is available up to 50°C with only 18 CFM airflow needed for 250W. It operates up to 70°C with derating or delivers up to 200W with convection cooling. Enclosed in a rugged U-channel chassis, the converters measure only 8 in. × 4.2 in. × 1.5 in. It's ideal for applications that require a 1U low profile, tight space requirements or where insufficient system air is available and a convection cooled rating is required.

These high-current 1700V IGBTs feature a Light Punch Through (LPT) vertical structure manufacturing process, enabling use of a lower cost float zone starting wafer. The LPT process also provides a positive temperature coefficient of Vce (sat) for simplified parallel operations. Also, they're targeted for high-power inverter applications for utility interface, 690Vac motor drives and light rail applications.
