New Polytron Devices’ DC-DC Converters Maintain Patient Protection for Low-Wattage Medical Devices


NORTHVALE, New Jersey, USA – New Yorker Electronics has released the newest medical electronics product from Polytron Devices. Low-Leakage, High-Efficiency Converters Attain Maximum Level of Safety Standards for Electrical Medical Products. Polytron Devices has recently introduced a family of 2- and 3.5-watt DC-DC converters for medical applications.

The 2:1 input range MTWA2 and MTWA4 2-watt and 3.5-watt DC-DC converters feature a low leakage current of 2μA and offer 5000V AC input to output isolation and 2 x MOPP patient protection —the highest level according to IEC 60601-1 safety standards for electrical medical products. They also offer up to 82 percent efficiency, remote ON/OFF and a high operating altitude of 5,000 meters. Safeguards include over voltage, short circuit and under voltage protection with no minimum load requirement.

The devices cover an extra-wide input range of 4.5V to 12VDC as well as 9V to 18VDC, 18V to 36VDC and 36V to 75VDC input ranges. With their low leakage current and their availability in miniature DIP16 (0.95 x 0.57 x 0.41 inches) and SMD16 (0.95 x 0.57 x 0.40 inches) packages, the MTWA2 and MTWA4 are especially desirable for use in portable devices with low wattage requirements.

In addition to their IEC 60601-1 Medical safety approval, the units comply with the RoHS 2011/65/EU Directive. The MTWA2 and MTWA4 Series DC-DC converters with 2:1 input range are both available in 4:1 input versions —MTWB2 (2 watts) and MTWB4 (3.5 watts), respectively.
