Artesyn Fanless Conduction-Cooled LCC250 Series

Artesyn Fanless Conduction-Cooled LCC250 Series

FULLY-ENCLOSED CONDUCTION OR CONVECTION COOLING FOR USEABLE POWER AT HIGH TEMPS

The LCC250 AC-DC power supply is a fully-enclosed conduction or convection cooled series delivering full useable power at high temperatures. The LCC250 series, with IP64 rated protection against the ingress of dust and water, is ideal for applications such as outdoor signage and telecom installation like antenna and base station equipment. The power supplies are equally suitable for indoor use, such as in control consoles, indoor signage and desktop equipment for medical applications, where the absence of cooling fans can help minimize dust and audible noise.
