CCB250 Series 250 W Convection Cooled 300 W Peak Rating 500 ms Very High Efficiency up to 95% 1U Form Factor 5 V Standby Rail 80 V - 275 VAC Input Operation IT & Medical (BF)Safety Approvals Remote On/Off & Power Fail Signal as Standard The CCB250 range of single output AC-DC 250 W nominal, 300 peak power supplies feature industry leading useable efficiency of 93% 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) open frame design which can be easily installed into end applications due to a significant 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 (BF) and IEC62368-1 IT safety approvals. The CCB250 series also boasts low earth leakage current of typically 60 A at 115V and 110 A at 230V, class B conducted emissions, 5V standby rail, power fail signal and remote on / off.xppower.com Models and Ratings - Convection-cooled Output Power Output Current V1 Output Voltage V1 Standby Supply Model Number (1) (1) P nom P peak I nom I peak 250 W 300 W 12.0 VDC 20.8 A 25 A 5.0 V/0.5 A CCB250PS12 250 W 300 W 15.0 VDC 16.7 A 20 A 5.0 V/0.5 A CCB250PS15 250 W 300 W 24.0 VDC 10.4 A 12.5 A 5.0 V/0.5 A CCB250PS24 250 W 300 W 28.0 VDC 8.9 A 10.7 A 5.0 V/0.5 A CCB250PS28 250 W 300 W 36.0 VDC 6.9 A 8.3 A 5.0 V/0.5 A CCB250PS36 250 W 300 W 48.0 VDC 5.2 A 6.25 A 5.0 V/0.5 A CCB250PS48 Notes: 1.
