New 600W power supply delivers full useable power at high temperatures

Artesyn Embedded Technologies has launched the LCC600 series, a new family of fanless, conduction-cooled AC/DC power supplies that can deliver their full 600W power output across a wide operating temperature range of minus 40C to 85C. Unlike many power supplies on the market, which typically require output derating above approximately 55C, an Artesyn LCC600 supply fed from a nominal 110VAC input is capable of maintaining its full 600W load capacity up to its maximum baseplate temperature of 85C. This is especially cost-effective for users who would otherwise need to budget for larger or additional power supplies. The LCC600 power supply features a universal 90-264VAC input with optional 180-305VAC input - enabling it to be used virtually anywhere in the world without adjustment. The first models available feature a single 28 or 48VDC output, with wide adjustment, and 5V standby voltage output. It measures 228mm x 101mm x 39.8mm and offers a typical efficiency is 93 percent. The Artesyn LCC600 power supply is housed in a robust fully-sealed enclosure with optional IP65 protection against the ingress of dust and water. This makes it ideal for applications that require the power supply to be located in the same outdoor environment as the equipment it is powering, such as bulk power for outdoor signage and for telecom installations such as antenna and base station equipment. The power supply is equally suitable for indoor use, such as in control consoles, indoor signage and medical applications, where the absence of cooling fans can help minimize dust and noise. The LCC600 power supply is fully approved to the international EN60601-1 medical safety standard and can be used in non-patient contact and non-patient critical equipment. Artesyn will expand the series to include other voltage output models, says the company.
