Daburn Electronics and its Polytron Devices division have launched the MUI50 Series of AC/DC medical power supplies. Accepting 85 to 264V, these universal input units deliver up to 50 W of continuous power and include a peak power function that allows up to 140% of rated output power for 5 seconds.
The Isolation Class I and II power supplies 4,000V AC reinforced 2 x MOPP insulation to protect against shock and electrocution, 5,000V AC input to output isolation, and a low leakage current of less than 100 µA. Additional safeguards include adjustable voltage output, overcurrent, overvoltage, and short circuit protection as well as EMC compliance.
Featuring a high efficiency of up to 92.5%, the MUI50 medical-grade power supplies operate from -40 to 131°F (-40 to 55°C) without derating and up to 185°F (85°C) with derating or forced air cooling. Their compact 3 x 1.5-inch open frame package makes them ideal for pulse oximeters, handheld ultrasound devices, mobile C-arm systems, ambulatory infusion pumps, and ECG monitors.
