- 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 t o 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 Medi cal (BF) and IEC60950-1 IT safety approvals. The CCB250 series also boasts low earth leakage current of typically 60 μA at 115V and 110 μA at 230V, class B conducted emissions, 5V standby rail, power fail signal and remote on / off.

xppower.com 23-Sep-13 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 be low must not be exceeded. Temperature should be monitored using K type thermocouples placed on the hottest part of the component (out of any di rect air flow). See Mechanical Details for component locations. Service Life Estimated Service Life vs Component Temperature Temperature Measurements (Ambient ≤ 50 ºC) Component Max Temperature ºC L2 120 ºC C12 105 ºC C21 105 ºC The estimated service life of the CCB250 Series is determined by the cooling arrangements and load conditions experienced in th e 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 tem perature. 5000 25000 45000 65000 85000 105000 125000 145000 165000 185000 105 95 85 75 65 C64 Temperature (°C) Lifetime (Hrs) Figure 20
