Emerson Network Power adds 24 V model to Sealed LCC250 Conduction Cooled 250 Watt Power Supply Series

Carlsbad, CA (PRWEB) November 01, 2011

Emerson Network Power, a business of Emerson and the global leader in enabling Business-Critical Continuity, today announced a new 24 Vdc output model in its LCC250 series of sealed 250 watt fanless ac-dc power supplies. Ideal for demanding sealed box and outdoor applications, the LCC250 power supply series includes conduction-cooled models providing full useable power at elevated temperatures.


With a wide operating temperature range of minus 40 to 85 degrees Celsius, Emerson Network Power LCC250 power supplies are housed in a robust fully-sealed enclosure offering IP64 protection against the ingress of dust and water. This makes them 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 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. LCC250 power supplies are fully approved to the international EN60601-1 safety standard for medical electrical equipment.


LCC250 power supplies have a very compact form factor, enabling them to be accommodated easily in end users equipment. There is a choice of mounting types; conduction-cooling and convection-cooling. All models have a small 7 inch by 4 inch (178 mm by 101 mm) footprint; the conduction-cooled versions have a height of just 1.1 inch (28 mm), while the convection-cooled versions feature an integral low profile heat sink which raises their overall height to 1.5 inch (38 mm). Both imperial and metric mounting holes are provided as standard, and the use of substantial 12 inch length (300 mm) cables for the ac input, dc output and control connections further simplify installation.


The conduction-cooled models introduce a new level of power flexibility. Unlike many power supplies on the market, which typically require output derating above approximately 55 degrees Celsius, Emerson Network Power LCC250 supplies fed from a nominal 115 Vac input are capable of maintaining their full 250 W load capacity up to their maximum baseplate temperature of 85 degrees Celsius. This makes them especially cost-effective for users who would otherwise need to budget for larger or additional power supplies.


LCC250 power supplies feature a universal 90-264 Vac, 47-63 Hz input enabling them to be used virtually anywhere in the world without adjustment and the new LCC250-24V-xP produces a single 24 Vdc output, adjustable by plus or minus 15 percent, capable of delivering 250 W max. For maximum safety, both live and neutral lines feature internal fuses.


Active power factor correction is employed to minimize input harmonic current distortion. The power supplies have a safety-ground leakage current of less than 275
