30-40 WATT MEDICAL POWER SUPPLIES
TM41 SERIES
( LV D )
The TM41 series of compact, open PCB constructed,
AC-DC switching power supplies are capable of
delivering 30 to 40 watts of continuous output power.
They operate at 85 to 264VAC input voltage without
the need of voltage selection. They are ideally suited
for use in medical equipments, safety systems and
monitoring equipments.
