About 1768-PB3

The Allen-Bradley 1768-PB3 is a CompactLogix Power Supply. The 1768-PB3 supplies power via the CompactLogix backplane. By using this backplane the 1768-PB3 power supply is compatible with 1768 and 1769 controllers, Input/Output modules and power supplies. Not only can the 1768-PB3 supply power through the backplane but it can also function as a 24 Volt DC external power supply. This input power supply offers a range of 16.8 to 31.2 Volts DC. In the same bank, a 1768 CompactLogix controller will need to be installed before the system is powered. This will power both the 1768-PA3 and 1768-PB3. The power supply can send 24 Volts DC to controllers located on the right of the power supply, or the right of the communication and motion modules. 

The 1768-PB3 CompactLogix Power Supply is constructed to weather power losses without affecting the operation of the system; this is referred to as ride-through time. The input/output type will drive the duration of ride-through time, which is typically 5 milliseconds for the 1768 PB3 power supply. Typically when operating at 24 Volts DC, the efficiency of the 1768-PB3 is 80%. The power dissipation of this module is around 22 Watts. In order to protect this power supply module from an internal overcurrent, a non-replaceable fuse has been soldered in place. Power supply modules operate most accurately at a temperature of 0 to 60 degrees Celcius. Please note for installations purposes the 1768-PB3 CompactLogix Power Supply has an open enclosure rating. This module measures 5.17 x 5.23 x 4.15 inches in total and weighs 2.2 pounds.
