Description: Allen-Bradley 1768-PA3 is a CompactLogix power supply. The power supply has an input voltage range of 85-265VAC or 108-132VDC. It has 15A integrated overcurrent protection. The power supply provides current for the midplane and supplies power to the modules connected to the midplane.

1768-PA3 is a CompactLogix power supply. The power supply is specially designed for the 1768 product family. It is a power supply with optional inputs, operating voltage classes of 85-265VAC or 108-132VDC. The power module provides the midplane power supply. The connected module uses the midplane power supply to power its circuits. This power supply does not provide output power for the output module. The 1768-PA3 has a maximum input power of 120VA / 120W, depending on the input voltage.

The 1768-PA3 power supply is compatible with 1768 CompactLogix controllers such as 1768-L43, 1768-L43S, 1768-L45, and 1768-L45S. When mounting modules into any 1768 rack, it is important to consider the power distance rating for each module. The power distance rating ensures that the module is still able to receive the necessary backplane power from the power supply. It also ensures that the size of the power supply is appropriately increased. If used with the 1769 compact I/O module, the 1768-PA3 can accommodate up to eight (8) modules in the same group. In the 1768 system, the rated distance is the distance between the 1769 I/O module and the controller.

A power module is an electronic module that converts alternating current to direct current, which is usually used to provide a stable power supply for electronic devices.

The 1768-PA3 power module typically includes one or more input ports for receiving alternating current, and one or more output ports for providing direct current. The power module can adjust the input voltage and output voltage to meet the power requirements of different devices.

Power modules generally have a high degree of reliability and stability, and are easy to install and configure. It can be managed and monitored through network management software to ensure the normal operation of the system.

Power modules can be used in various applications, such as computers, servers, switches, routers, industrial automation equipment, etc. In these applications, the power module can provide a stable power supply for the device to ensure the normal operation of the device.
