Enclosed supplies deliver full power at 85°C

The LCC250 enclosed 250-W fanless ac/dc power supplies feature a 12-Vdc output and an operating temperature range from –40° to 85°C. They provide IP64 protection against dust and water, and suit sealed box and outdoor applications including outdoor signage and telecom installations such as antenna and base station equipment. The supplies are also suitable for indoor use, such as control consoles, indoor signage, and desktops for medical applications.

The 7 x 4-in. enclosed power supplies feature a 90 to 264-Vac input at 47 to 63 Hz. They achieve 89% efficiency at full load and offer conduction or convection cooling. The 1.1-in.-high conduction-cooled supplies maintain 250-W load capacity up to 85°C. The convection-cooled versions feature an integral heat sink with a height to 1.5 in. The 12-Vdc output is adjustable by ±10%. (Ea/prod qty: conduction version, $98.20; convection version, $103.85 — available now.)
