Cosel adds medical isolation grade power supply to PJMA series 

A 300W power supply has been added by Cosel to its PJMA series. The PJMA300F has a universal input range of 85 to 264V AC and complies with international safety standards. 

It is designed for demanding medical applications, and is suitable for body floating (BF) applications and complies with 2MOPP (means of patient protection) and 1MOPP safety requirements. 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. Cosel’s PJMA series can be operated within the so-called ‘universal input’ range of 85 to 264V AC and has a typical efficiency of 86 per cent at high line.

Four single output voltages are available as standard, 12V / 25A, 24V / 12.5A, 36V / 8.4A, and 48V / 6.3A. The output voltage can be adjusted by using the built-in potentiometer.

The PJMA series includes inrush current limiting circuitry, over-current, over-voltage protection and thermal protection. The power supplies operate across 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 is built in an enclosed, galvanised steel box with a fan mounted on the rear side. The PJMA300F measures 102 x 41 x 190mm [4.02 x 1.61 x 7.48 inches] and weigh 1.0kg max.

With the addition of the PJMA300F, the PJMA series covers from 300W up to 1000W (PJMA1000F), including a 600W version (PJMA600F).

All units in the PJMA series 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 can be supplied (NAC-06-472).

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).

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