EMH Series: 250 W and 350 W AC-DC Supplies

XP Power launches their 250/350 W range of AC-DC supplies in an ultra-compact 3 x 5 inch footprint

Image of XP Power's EMH Series, 250 W and 350 W AC-DC SuppliesXP Power announces the EMH250 and EMH350 series of highly-efficient single-output 250 W and 350 W AC-DC power supplies. Meeting the IT equipment safety specifications of UL/TUV/EN 60950-1 and the stringent medical safety standards of UL/TUV/EN 60601-1, the EMH series suits a broad range of information technology, industrial, medical equipment, and surgical life-support applications. All models are also BF rated.

Both the EMH250 250 W and the EMH350 350 W series have an extra-wide-input range of 80 VAC to 275 VAC and are available in four-output models covering the nominal voltages of 12, 18, 24, or 48 VDC. A trim function allows adjustment of the output voltage to within ±10% of stated nominal. A 12 VDC/0.6 A fan supply is also provided across the range. The EMH350 series also includes a 5 VDC/2.0 A standby supply. Unlike many competitor models, full-power is available from low-input voltages of 90 VAC and the unit does not derate until 50°C operating temperature.

Measuring just 76.2 x 127 x 36.3 mm (3 x 5 x 1.43 inches), these industry-standard format units require only 12 CFM of forced airflow in order to deliver the full-output power. An optional top-mounted fan is available across the range, and the EMH350 has the additional option of a variable speed fan that is dependent on the unit’s operating temperature.

The EMH350 series is also available with an optional O-Ring diode circuit that allows for current sharing in N+1 redundancy configurations. This series provides customers with the choice of either analog or digital control options. The analog signals provide power fail, inhibit, and current share. Digital signals and controls are accessible using PMBus-compatible commands.
