300 WATT MEDICAL POWER SUPPLIES
TRUMPower
The TM300 series comprising single and multiple
output models for 200 to 300 watts of continuous
output power is specially designed for medical
applications. They operate at 90 to 264VAC input
voltage without the need of a selector strap. All
auxiliary outputs are with magnetic amplifier to
keep regulation. The units are constructed on a
