TRUMPower
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.
