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