PU110_14 Datasheet, PDF (1/2 Pages) RSG Electronic Components GmbH – 72-110 WATT ITE POWER SUPPLIES

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.

INTERFACE SIGNALS
PFD:
TTL logic high for normal operation and TTL logic low
upon loss of input power. This signal appears at least
1 ms prior to +5V output dropping 5% below its
nominal value. This signal also provides a minimum
delay of 100 ms after +5V is within regulation.
