30-40 WATT MEDICAL POWER SUPPLIES

DES C RI P T I O N

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.
