Cosel has added a 1500W AC-DC supply to its PJMA medical power range.

The 1500W PJMA1500F have a universal input range of 85 to 264VAC and is suitable for Body Floating (BF) applications, complying with 2MOPP (IN/OUT) and 1MOPP (OUT/FG) safety requirement.

The design has been optimized for price/performance in medical applications requiring a high quality power solution and is available in four output voltages of 12, 24, 36 and 48VDC with 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 a 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.

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