1768-PA3
The Allen-Bradley 1768-PA3 is a CompactLogix power supply module.
It is a dual-input power supply whose primary purpose is to provide
power through the CompactLogix backplane. This power supply
operates at 85 - 265VAC or 108 -132VDC. Before powering up the
system, install a 1768 CompactLogix controller in the same bank as
the power supply. To avoid issues, never install a 1769 power
supply to a 1768 CompactLogix backplane.
The 1768-PA3 module has an open-type enclosure and it can be
mounted using DIN rail or panel mount. LED status indicators let
the user monitor the module’s current state in real time. The
1768-PA3 can be from Series A or B and has a wiring category of 1
for the power ports. Its compatible wire sizes are 14 to 22 AWG
stranded or solid copper wire rated at 167 degrees Fahrenheit with
a maximum isolation of 1.2 millimeters. The 1768-PA3 has an
internal overcurrent protection due to the soldered non-replaceable
fuse. It also comes with a user-supplied maximum overcurrent
protection of 15 Amps and its typical efficiency rate is 75%, and a
maximum input power of 120 VA or 120 W. The 1768-PA3’s maximum
inrush current is 50 Amps at 85 to 132 Volts AC and 80 Amps at 195
to 265 Volts AC while its power dissipation is 30 W.
The Allen-Bradley 1768-PA3 is a CompactLogix Power Supply. This
Power Supply is used exclusively used for the 1768 product family.
It is a power supply with selectable inputs, operating at Voltage
categories of 85 - 265VAC or 108 -132VDC. This Power supply module
provides backplane power which is used by the attached module to
energize their individual circuitry. This power supply does not
supply output power to the output modules. The 1768-PA3 features a
maximum input power of 120VA / 120W, depending on the input
voltage.
The 1768-PA3 power supply is compatible for use with 1768
CompactLogix Controllers such as 1768-L43, 1768-L43S, 1768-L45 and
1768-L45S. When installing modules to any 1768 rack, It is
important to consider the power supply distance rating of each
module. Power Supply distance rating ensures that the module will
still be able to receive the necessary backplane power from the
power supply. It also ensures that the power supply is
appropriately sized up. If used with 1769 Compact I/O modules, the
1768-PA3 can accommodate up to Eight (8) modules in the same bank.
In the 1768 system, the distance rating is the distance between
1769 I/O modules and the controller.
This power supply is provided with a single LED indicator. Ideally,
when power is applied, the LED should turn Green. If the LED
remained OFF, verify if the input power is active, a short or
overload might be active in the 1768 system or the power supply
needs to be replace. When this LED indicator turns RED, it may mean
that the power output to the backplane is not valid, the controller
needs to be replaced or a communication, motion module is
defective.
