DESCRI PTI O N

The TM25 series of compact, open PCB constructed,

AC-DC switching power supplies are capable of

delivering 25 to 28 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.
