XP Power has announced the launch of the CMP250 series of high peak power AC-DC power supply units, primarily targeting healthcare, industrial and IT applications. Offering a flexible combination of electrical and thermal characteristics, the power supplies deliver up to 500 Watts of peak power for up to 60 seconds, as well as providing 250 Watts of continuous convection-cooled power. This high level of flexibility makes the series ideal for motor applications and other electromechanical loads without the need for fan cooling across a range of applications.
For medical applications, the CMP250 has an input/output (I/O) isolation of 4 kVAC, provides 2 x MOPP (Means of Patient Protection) I/O isolation and 1 x MOPP isolation from both input to ground and output to ground, all rated at the AC input voltage. Maximum earth leakage current of 250uA coupled with a maximum patient leakage current of 80uA and these isolation characteristics make the CMP250 an ideal choice for Body Floating (BF) applications, targeting a range of equipment such as surgical tools, motorised beds and chairs, use in life support and imaging products. In addition, the series is suited to a variety of industrial and IT applications, especially supporting those applications that have requirements for long-duration peak currents to drive equipment such as printers and other electromechanical loads.
The supply’s peak-power capability of 500 W offers reduced expenditure for companies, rather than implementing a power supply that is rated for continuous operation at more than 250 W. Operating over the –40 to +70 °C temperature range with derating above +50 °C, the series offers a typical high efficiency of 89% along with a very flat efficiency curve across the entire load range. The efficiency performance means less dissipated heat enabling a convection-cooled design and negating the need for system fan cooling.
Supplied in a low-profile 1U-high chassis and 7.5 x 4-inch footprint and operating from a universal 80 to 264 VAC input, the series is available in three different models, respectively offering outputs of 24, 36 or 48 VDC. Other key features of the unit include constant-current overload characteristics, a 5V/1.5A standby output and a 12V/0.6A auxiliary output. Additional features include: remote sense, output inhibit, AC OK/Power Fail signal and the ability to current share up to three units in parallel. These features provide many options to the end system designer. Specific dimensions of the CMP250 series are 190.5 x 101.6 x 39.9mm; the series also comes in a covered version with dimensions of 200.5 x 104.6 x 48.8mm.
Respective IT and medical safety application approvals for the series include: IT EN/IEC/UL60950-1 and EN/IEC/UL62368-1; and ANSI/AAMI ES60601-1, EN60601-1 and IEC60601-1. The series also meets EN55032/11 Class B conducted and Class A radiated emissions. The ability to meet Class B radiated emissions is also possible with additional external components.
The series is available from Digi-Key, element14, Farnell, RS Components, approved regional distributors, or direct from XP Power and come with a 3-year warranty.
