Datasheet

## **ARTESYN LCC250** 

250 Watts Convection/Conduction Mounting 

Advanced Energy's Artesyn LCC250 AC-DC power supply is a fully-enclosed conduction cooled series delivering full useable power at high temperatures. The LCC250 series, with IP64 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 desktops for medical applications, where the absence of cooling fans can help minimize dust and noise. 

## **AT A GLANCE**

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Request a quote →

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
