Datasheet

Suitable for applications requiring a dual output supply in an industry standard 4x6" footprint, the dual output EMH350 series have been introduced by XP Power. The highly efficient (typically 87%) AC-DC power supplies offer two outputs rated up to 200W each with a combined maximum output of 350W.

The EMH350 series consists of five different models offering a combination of six different output voltages from 12-60V DC, or they can be connected in series to provide a single output up to 120V DC. All models also include an additional 12V 0.6A fan output and a 5V 2A standby output, as well as signal and control functions including AC OK/power fail, inhibit, current share and remote sense.

The EMH350 series is also offered in two different mechanical versions: the ‘U’ channel format measures 101.6x152.4x39.8mm (4.00x6.00x1.57") and is available without a fan; while an end-fan option is available that integrates a variable speed fan and adds 25.4mm (1") to the length and 4.7mm (0.18") to the height. Only 16CFM of external cooling is required for the ‘U’ channel format. The operating temperature range for both versions is from 0 to +70°C with no derating until +50°C.

The EMH350 series AC-DC power supplies are compliant with the international recognised safety standard UL/EN/IEC 60950 for IT equipment and the 3rd edition medical safety standard ANSI/AAMI/EN/IEC 60601, including risk management. This medical approval covers body floating applications where the end equipment may be connected to the patient. Additionally, the 350W power supplies meet EN55011/22 Level B for conducted emissions and are supplied with a three year warranty.
