COSEL, a leading designer and manufacturer of high performance AC-DC Power Supplies, DC-DC Converters and EMI Filters, has announced the expansion of its medical power offering with the addition of a 1500 W version to its PJMA series. The 1500 W PJMA1500F has a universal input range of 85 to 264 VAC and complies with international safety standards. Designed for demanding medical applications, the PJMA series is suitable for Body Floating (BF) applications and complies with 2MOPP (IN/OUT) and 1MOPP (OUT/FG) safety requirement. 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, 24, 36 and 48 VDC.
The PJMA series can be operated within the so called ‘universal Input’ range of 85 to 264 VAC, and has a typical efficiency, up to, 88% at high line. Four single output voltages are available as standard, 12V/125A, 24V/64A, 36V/42A, and 48V/32A. 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 to 70 degrees centigrade. 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. In conducted emission tests, the PJMA1500F complies with the FCC-A, VCCI-A, CISPR32-A, EN55011-A and EN55032-A.
To accommodate application specific requirements, a number of options are available including conformal coating (C), low leakage current (G), external potentiometer connector (V), remote control (R), and low speed fan (F4). For strength and longevity, the PJMA series is built in an enclosed, galvanized steel box with a fan mounted on the rear side. The PJMA1500F measures 178 x 61 x 268mm [7.01 x 2.40 x 10.55 inches] (W x H x D), and has a weight of 3.5 kg max.
