Polytron Helps Get Critical Medical Devices Into the Field

Medical device design and manufacturing has changed dramatically in 2020 as the global pandemic has imposed new supply chain pressures on OEMs. If your devices need DC-DC or AC-DC converters, Polytron Devices can help by continuing to offer stable, predictable lead times.


Our medical power electronics perform reliably and safely, making them suitable for use in devices that have close proximity to patients. They exhibit low leakage currents, meet or exceed IEC 60601-1 requirements and satisfy two means of patient protection (2 MOPP) standards to protect patients against electrocution as well as help ease the device manufacturer’s safety and EMC approval process.

Polytron products are found in a wide range of medical devices and settings such as diagnostic and therapy equipment, home nebulizers and blood pressure monitors, surgical tools with lights, lasers or video capabilities, endoscopic and 3D laparoscopic devices, pain monitoring devices and dental chairs. Our medical power converter lineup includes certain models that may be appropriate for critical devices related to the COVID-19 outbreak. For example, two products that are well-suited for ventilator power include:

MUI270-44SP-A universal-input, 270-watt medical power supplies

This model — part of Polytron Devices’ MUI310-A Series of 230- to 310-watt medical power supplies with 2 MOPP patient protection — comes in a 7.78 x 4.01 x 2.01-inch desktop form factor suitable for portable devices in a variety of healthcare environments. Reliability features include built-in over-voltage, over-current, over-temperature and short circuit protections. The MUI270-44SP-A also offers MTBF greater than 100,000 hours, 4,000V AC input/output isolation, an active PFC function, 87.5 percent efficiency, input voltage range of 90 to 264V AC, 44-V output voltage, maximum load current (Io) of 6.13A, 840-mV (peak to peak) ripple and noise and ±5 percent load and ±1 percent line regulation.

MUI65-15SB 65-watt AC-DC converters

With a universal input range of 85 to 264V AC and high efficiency up to 92 percent, the 65-watt MUI Series of AC-DC converters has a low leakage current under 75 µA and a built-in EMI class A filter. The MUI65-15SB also offers 0.11-watt low standby power consumption, 2,000V AC input to output 2 MOPP isolation, 24V output voltage and 4.34A output current. To satisfy ever-shrinking medical device designs, the converters come in a space-saving 2.00 x 3.00 x 1.16-inch package. Enclosed mounting is standard, with screw terminal, chassis mount, DIN rail and open-type mounting options also available.

While the COVID-19 emergency has created shipping constraints across the electronics industry, Polytron Devices’ shipping capabilities have suffered minimal effects. Our shipping hours remain the same, and we have maintained our normal monthly shipping capacity to help you meet your time-to-market needs.
