XP Power Ltd. today announced the dual output EMH350 series of 350-Watt ac-dc power supplies aimed at a broad range of applications that require a dual output supply in an industry standard 4 x 6 inch footprint. These highly efficient units, typically 87% efficient, provide two outputs rated up to 200 Watts each with a combined maximum output of 350W. The series comprises five different models with a combination of six different output voltages from 12 to 60 Vdc. Outputs are also capable of being connected in series in order to provide a single output up to 120 Vdc. All models include an additional 12 V / 0.6 A fan output and a 5 V / 2 A standby output. Signal and control functions include AC OK/power fail, inhibit, current share and remote sense.
Two mechanical versions of the EMH350 are available. A 'U' channel format measuring 4.00 x 6.00 x 1.57 inches (101.6 x 152.4 x 39.8 mm) is available without a fan, or the end-fan option that integrates a variable speed fan and adds 1 inch (25.4 mm) to the length and 0.18 inches (4.7 mm) to the height. When using the 'U' channel format external cooling of only 16 CFM is required. The operating temperature range is from 0 to +70 degrees C with no derating until +50 degrees C.
The EMH350 series complies with both the international recognized safety standard UL/EN/IEC 60950 for IT equipment and the 3rd edition medical safety standard ANSI/AAMI/EN/IEC 60601, including risk management. The medical approval covers body floating (BF) applications where the end equipment may be connected to the patient. The units meet EN55011/22 Level B for conducted emissions. The EMH350 dual output U channel model is priced at $199 in 500 pc quantities and come with a 3-year warranty.
