Japan-based COSEL Co. Ltd has expanded its medical power offering with the addition of the PJMA series. The 600 W PJMA600F and the 1000 W rated PJMA1000F have a universal input range of 85 V AC to 264 V AC and comply with international safety standards. Designed for demanding medical applications, the PJMA series input/output isolation complies with 2MOPP requirements. Based on a robust platform, the units’ design has been optimized to offer a very good price/performance ratio for medical applications requiring a high quality power solution. The PJMA series is available in four output voltages of 12 V DC, 24 V DC, 36 V DC and 48 V DC.
Medical applications are requiring robust and highly reliable power supplies that are able to operate around the world and comply with safety regulations. In response, COSEL power designers developed an optimized platform to offer an excellent price/performance ratio without compromising on quality and

Four single output voltages are available as standard in each unit. That is 12 V/50 A, 24 V/25 A, 36 V/16.7 A and 48 V/12.5 A for the PJMA600F, and 12 V/84 A, 24 V/42 A, 36 V/28 A and 48 V/21 A for the PJMA1000F. The output voltage can be adjusted by using the built-in potentiometer.
The PJMA series includes inrush current limiting circuitry, overcurrent and overvoltage protection, as well as thermal protection. Exhibiting versatility and robustness, the power supplies can be operated in an environmental temperature range of -20° C to 70° C. Depending on the final equipment assembly style and cooling conditions, a derating may apply.
With its medical focus, the PJMA series input to output isolation complies with 2MOPP, its input to ground with 1MOPP, and output to ground with 1MOPP. The units are approved in accordance with ANSI/AAMI ES60601-1 and EN60601-1 3rd Edition.
