Wide Input Power supplies Tout User Flexibility
Altech’s “PSW Series” AC/DC DIN rail power supplies feature a input voltage range (180 VAC to 550 VAC and 254 VDC to 780 VDC) for use in general power system applications with single phase 230 VAC input or two phases from the 220 V to 550 VAC three-phase power system. This product family offers up to 93 percent efficiency. Typical applications include industrial control systems, semiconductor fabrication equipment, factory automation, electro-mechanical applications, and marine-related installations, among others. PSW Series power supplies can deliver 100 percent power continuously at 50ºC by free air convection or can operate under 70ºC ambient temperature with suitable derating. Standard features include a built-in DC OK relay contact enabling users to confirm remotely that the power supply is operating as required, a built-in active PFC function, and 100 percent full load burn-in test. The power supplies are cooled by free air convection and incorporate multiple protections against short circuits, overload, over voltage, and over temperature. PSW power supplies mount on DIN rails, install with universal AC input, comply with UL508 and IEC60950-1 (CB) standards, and meet the EMC requirements of heavy industrial immunity level (EN61000-6-2). They are CE marked.
