Cosel adds to medical power supplies with 600W and 1,000W options

Medical power supplies from Cosel now include the PJMA series. The 600W PJMA600F and the 1000W rated PJMA1000F have a universal input range of 85 to 264V AC and comply with international safety standards.

They are designed for demanding medical applications, and feature I/O isolation to comply with 2MOPP (means of patient protection) requirements. Both the 600W PJMA600F and the 1000W rated PJMA1000F medical power supplies have been optimised for high power medical applications. The PJMA series is available in four output voltages of 12, 24, 36 and 48V DC.

Medical applications require robust and reliable power supplies that are able to operate around the world and comply with safety regulations.

The PJMA series can be operated within the so called universal input range of 85 to 264V AC, and has a typical efficiency of 88 per cent at high line.

Four single output voltages are available as standard in each unit. The PJMA600F output is 12V/50A, 24V/25A, 36V/16.7A, and 48V/12.5A and the PJMA1000F has 12V/84A, 24V/42A, 36V/28A, and 48V/21A options. The output voltage can be adjusted by using the built-in potentiometer.

Other features of the PJMA series include inrush current limiting circuitry, over-current and over-voltage protection, as well a thermal protection. The versatile and robust power supplies operate in an environmental temperature range of -20 to +70 degrees C. Depending on the final equipment assembly style and cooling conditions, a derating may apply.

The PJMA series’ input to output isolation complies with 2MOPP, and both its input to ground and output to ground comply 1MOPP. The units are approved in accordance with ANSI/AAMI ES60601-1 and EN60601-1 3rd Edition.

In conducted emission tests, the PJMA series complies with the FCC-B, CISPR11-B, CISPR32-B, EN55011-B, EN55032-B, and VCCI-B. For applications requiring even lower emission levels an additional filter Cosel type NAC can be supplied (NAC-16-472 for the PJMA600F and NAC-20-472 for the PJMA1000F).

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), remote sensing / low output voltage alarm and parallel operation (W), and low speed fan (F4).

The power supplies are built in an enclosed, galvanised steel box with fans mounted on the rear side (one for the 600W and two for the 1000W).

The PJMA600F measures 120 x 61 x 215mm (4.72 x 2.40 x 8.46 inches) and weighs 2.0kg (max). The PJMA1000F measures 150 x 61 x 240 (5.91 x 2.40 x 9.45 inches) and has a weight of 2.8kg (max).

The PJMA series has a five-year warranty and conforms to the European RoHS, REACH and Low Voltage Directives.
