Housed in a small package measuring 168 x 78 x 43 mm and weighing 800 g, the PCM80 from XP is a compact, 80 W external power supply designed for medical applications. The power supply operates at 83% typical efficiency with noise and ripple of less than 1% peak-to-peak.
Available in a choice of 15 single, nine dual, and six triple-output versions, it features less than 300 µA leakage current at 230 V a.c. and has 4000 V a.c. isolation from input to output - both essential requirements for patient safety. To comply with European safety agency requirements both line and neutral are fused.
The PCM80 has a universal AC input of 90 to 240 V a.c. and line regulation of ±1% maximum at full rated load. Load regulation is within ±5%, except for the 3,3 V model, where it is within ±7%. Overvoltage protection is provided on output 1 and overcurrent protection, with auto recovery, applies to all outputs. The power supply operates from 0 to +70°C ambient with linear derating from 100% load at +40 to 50% load at +70°C.
The product family has medical safety approvals to all major agencies and meets EN55011 (CISPR11) Class B for conducted and radiated emissions. Active power factor correction ensures EN61000-3-2,-3 compliance.
