110 WATT SWITCHING POWER SUPPLIES
DESCRIPTION
(LVD)
RoHS
The PU110 series of compact, open PCB constructed,
AC-DC switching power supplies are capable of delivering
72 to 110 watts of continuous power at 25 CFM forced air
cooling or 52 to 80 watts at convection cooling. They
operate at 85 to 264VAC input voltage without the need of
a selector strap. They are ideally suited for use in small to
medium
size
digitally-based
systems,
such
as
point-of-sale equipment, microprocessor based systems,
and telecom equipment. All models meet the safety
requirements of UL, CSA and IEC.
