450 WATT MEDICAL POWER SUPPLIES

DESCRIPTION

(LVD)

TM450 SERIES

The TM450 series comprising single and multiple

output models for 450-480 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. The

units are constructed on a printed circuit board

with a U-bracket for mechanical support and heat

sinking. A cover-and-fan assembly can be added

during manufacturing.

RoHS
