72-110 WATT ITE POWER SUPPLIES
DESCRIPTION
The PU110 series of compact, open PCB constructed,
AC-DC switching power supplies are capable of
delivering 72-110 watts of continuous power at 25 CFM
forced air cooling or 60-80 watts at convection cooling.
They operate at 85-264 VAC 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.

NOTES:
1.
Peak output current with 10% maximum duty cycle for less than 60 seconds. Total peak power must not exceed 130 watts.
2.
110 watts maximum at 25 CFM forced air cooling or 80 watts maximum at convection cooling, except model PU110-10-1A which is rated
maximum 60 W at convection cooling or 72 W at 25 CFM forced air cooling.
3.
Safety agency approvals are for the above listed models in PCB format. To order models with metallic L-bracket or box, change suffix “A” to “B”
for L-bracket format, to “C” for enclosed format (mechanical details shown in page 71-72), e.g. PU110-31C.
4.
The output #1 of model PU110-45-1A needs a minimum current of 2 A to support the other outputs at their maximum rated loads
5.
Ripple and noise is maximum peak-to-peak voltage value measured at output within 20 MHz bandwidth, at rated line voltage and output load
ranges, and with a 10
μF
tantalum capacitor in parallel with a 0.1
μF
ceramic capacitor across the output.
