25-28 WATT MEDICAL POWER SUPPLIES
TM25 SERIES
( LV D )
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.

All multiple output models may be operated at no-load without damage. At no-load, output voltage tolerance
increases to 10%.
Ripple and noise: Peak-to-peak with 20MHz bandwidth and 10µF in parallel with a 0.1µF capacitor at rated line
voltage and load ranges.
Safety agency approvals are for the above listed models in PCB format. Add suffix “B” for L-bracket format, or
suffix “C” for enclosed format, e.g. TM25-T31C.
