The CCM250 range of single output AC-DC 250 W nominal, 300 peak power supplies feature industry leading efficiency of 95% and
absolute minimum efficiency of 90% with 90 VAC input and full load. This leap in efficiency has been achieved with full resonant ZCS
topology and careful consideration to every aspect of power loss resulting in a convection cooled power supply packaged in a 6”
(153mm) x 4” (102mm) x 1.5” (38mm) chassis which can be easily installed into the end application due to a 70% reduction in the
dissipated heat, associated with other power supplies in this power range.
The six standard models cover the voltage range from 12V - 48V , have dual input fusing and are compliant with IEC60601-1 Medical
and IEC60950-1 IT safety approvals.
The CCM250 series also boasts low earth leakage current of typically 90μA at 115V and 160μA at 230V, class B conducted and
radiated emissions 5V standby rail, power fail signal and remote on / off.

Power Loss
Waste heat creates a big headache for system designers. The industry leading efficiency achieved by the CCM250 is 5-10% above existing topologies
used in this power area. This can result in a 70% reduction in generated heat as shown below and enables the overall system to run much cooler and
more reliably.

Thermal Considerations
In order to ensure safe operation of the PSU in the end-use equipment, the temperature of the components listed in the table below must not be
exceeded. Temperature should be monitored using K type thermocouples placed on the hottest part of the component (out of any direct air flow). See
Mechanical Details for component locations.

Service Life
The estimated service life of the CCM250 Series is determined by the cooling arrangements and load conditions experienced in the end application.
Due to the uncertain nature of the end application this estimated service life is based on the actual measured temperature of a key capacitor within the
product when installed in the end application.
The graph below expresses the estimated lifetime for a given component temperature and assumes continuous operation at this temperature.
