Ideal for sealed box or no airflow applications such as medical desktops, clean roomapplications; can provide full power to 85 degrees Celsius

 

HONG KONG [20 February, 2012] – Emerson Network Power, a business of Emerson(NYSE:EMR) and the global leader in enabling Business-Critical Continuity™, expandedits LCC250 series of 250 Watt sealed fanless ac-dc power supplies with the addition of anew 48 Vdc model. With approval to the international EN60601-1 safety standard formedical electrical equipment, LCC250 power supplies are ideal for a wide range ofsealed box and desktop healthcare applications, where the absence of cooling fans canhelp minimize dust and noise. These power supplies are high efficiency designs,typically achieving 91 percent at full load.

 

The LCC250 power supply series includes conduction-cooled models providing fulluseable power at elevated temperatures. 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 arecapable of maintaining their full 250 W load capacity up to their maximum baseplatetemperature of 85 degrees Celsius. This makes them especially cost-effective for userswho would otherwise need to budget for larger or additional power supplies.

 

A robust fully-sealed enclosure provides the LCC250 series with IP64 protection againstthe ingress of dust and water. This makes them ideal for applications that require thepower supply to be located in the same outdoor environment as the equipment it ispowering, such as bulk power for outdoor signage and for telecom installations such asantenna and base station equipment. The power supplies are equally suitable for indooruse, such as in control consoles, indoor signage and desktops for medical applications.They are also capable of operating in constant-voltage or constant-current mode, whichis frequently a requirement for LED lighting applications.

 

A very compact 7 inch by 4 inch (178 mm by 101 mm) footprint enables them to beaccommodated easily in end users’ equipment. The conduction-cooled versions have aheight of just 1.1 inch (28 mm), while the convection-cooled versions feature an integrallow profile heat sink which raises their overall height to 1.5 inch (38 mm).

 

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 μA when fedwith a 250 Vac input, and provide an output hold-up time of at least 16 ms when fed witha 115 Vac input and delivering full load. Overcurrent and overtemperature protection arefully auto-recovering; overvoltage protection is latching and requires the ac input to berecycled before output power can be restored.

 

Safety approvals include UL/CSA/TUV 60950/60601-1, CE Mark (LVD), CB certificationand China CCC. The power supplies are also fully compliant with the Restriction ofHazardous Substances (RoHS) per EU directive 2002/95/EC.

 

The conduction and convection cooled versions of Emerson Network Power’s LCC250power supplies are available at the competitive prices of $103 and $109 respectively perunit in production quantities. Sample quantities are available now. For additionalinformation, please see the LCC250 websheet.
