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.
