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.
