The CMP250 series delivers up to 500 Watts of peak power for up to 60 seconds, as well as providing 250W of continuous convection-cooled power. This makes the series suitable 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 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. The maximum earth leakage current of 250μA coupled with a maximum patient leakage current of 80uA make the CMP250 suitable for Body Floating (BF) applications, targeting a range of equipment such as surgical tools, motorised beds and chairs used in life support and imaging products. The series is also 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.
It has a 1U-high chassis and operates from a universal 80 to 264 VAC input, 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. The footprint is 190.5 x 101.6 x 39.9mm
