The SHP350 series of single output rugged 350-W ac/dc power supplies suit industrial applications. They feature a power density of 6.6 W/in.3 and provide a typical efficiency of 85% in a fan-cooled unit measuring 7.0 x 3.6 x 2.1 in. They meet the SEMI F47 Voltage Sag Immunity standard for factory automation equipment.
The 350−W power supply series is made up of six single output models providing nominal output voltages from +12 to +48 Vdc. The output is also capable of being adjusted within ±10% in order to cater to non-standard voltage applications. A remote sense facility compensates for a voltage drop of up to 0.5 V due to line losses. An auxiliary output provides an always-on +5−Vdc / 0.2−A output suitable for powering memory, logic or control functions. The supplies accept input voltages from 85 to 264 Vac. When operated from input voltages above 180 Vac the power supply has a peak power capability that can deliver up to 420−W output for up to 10 s. They operate from −20° to +70°C, with derating at +50°C. ($152.10 ea/500 — available now.)
