　　Product Description:

　　The 1756-PA72 A-B standard power supply is a high-efficiency,reliable,durable,easy-to-use,and powerful module that can provide power to modules in the ControlLogix PLC chassis.This module can meet different application requirements and is widely used in various industrial control fields.

　　Allen Bradley 1756-PA72 is a ControlLogix standard power supply.The input voltage of this power supply is 85-265VAC,and the nominal power supply is 120V/240VAC.The current capacity at 3.3VDC is 4A;10 A at 5.1VDC and 2.8 A at 24VDC.Its rated output power is 75 W 0…+60°C(+32…+140°F).

　　Allen Bradley 1756-PA72 is a standard power supply primarily used to power the backplane of the 1756 ControlLogix chassis,enabling each module connected to the chassis to operate.1756-PA72 is designed to accept an input voltage range of 85-265 VAC and a frequency range of 47-63 Hz.It provides an output power of 75 W at 0-60°C(+32…+140°F)and a current capacity of 4A at 3.3VDC;10 A at 5.1VDC and 2.8 A at 24VDC.

　　The holding time of 1756-PA72 under 85VAC,50/60 Hz conditions is 5 cycles;6 cycles of 120VAC,50/60 Hz;6 cycles of 200VAC,50/60 Hz,and 6 cycles of 240V AC,50/60 Hz.Hold time refers to the response of the power supply to input voltage removal and DC power supply failure.

　　1756-PA72 is installed at the leftmost position of the chassis.It has a dedicated slot allocation outside the chassis and does not occupy ControlLogix slots.It can be installed in different ControlLogix chassis,such as 1756-A4,1756-A7,1756-A10,1756-A13,and 1756-A17,regardless of the A,B,and C series.The weight of this power supply is approximately 0.95 kilograms(2.10 pounds),and its physical dimensions are 14.0 x 11.2 x 14.5 centimeters(5.51 x 4.41 x 5.71 inches).This module,along with the ControlLogix chassis,has an open housing,so it needs to be installed inside the housing to protect the hardware from industrial pollutants and interference.1756-PA72 may not be suitable for redundant power applications,but it can also be used for distributed I/O architectures.

　　The power consumption of 1756-PA72 is 25 watts at 0 to 60 degrees Celsius(32 to 140 degrees Fahrenheit).The power consumption of this power supply is 85.3 BTU/hour,and the maximum surge current is 20 A.Allen Bradley 1756-PA72 provides built-in overcurrent protection.It is provided by the user with a maximum current of 15 A.The maximum transformer load of this power supply is 100VA,and the voltage isolation is 250V continuous voltage.1756-PA72 also underwent a 60 second reinforced insulation type test at 3500 volts DC voltage.Allen Bradley 1756-PA72 is an open device.The power supply should be installed in an appropriate enclosure designed specifically for specific environmental conditions.Only tools can be used to access the interior of the casing.

　　The 1756-PA72 A-B standard power supply is a metal module with 2 input terminals and 1 output terminal.The input terminal receives an 85-265 V AC power supply,and the output terminal provides a 24 V DC power supply.This module also has functions such as overcurrent protection,overvoltage protection,and short circuit protection.
