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.
