The 1756-PB72 is a standard DC Power Supply from the ControlLogix product line manufactured by Allen-Bradley/Rockwell Automation. The module is compatible with any chassis from the ControlLogix line, both Series A and Series B, and should be mounted on the left side. The approximate dimensions (HxWxD) of the power supply are 140 x 112 x 145 millimeters (5.5 x 4.4 x 5.7 inches) and its approximate weight is 1.1 kilograms (2.5 pounds). The 1756-PB72 requires a nominal power supply voltage of 24 Volts DC and it can operate on 18 to 32 Volts of DC power. The maximum input power this module can use is around 95 Watts and the power supply can output 75 Watts at 60 degrees Celsius. There are two durations for the Hold Up Time option depending on the voltage: 30 milliseconds at 18 Volts DC and 40 milliseconds at 24 and 32 Volts DC.

The power supply module comes with overcurrent protection of 15 Amperes. The part also features isolation voltage which can withstand 250 Volts continuous voltage, which was tested at  The conductor of the module are copper wires size 14 AWG, and the conductor Screw Torque is 0.8 N-m (7 inches per pound. The 1756-PB72 can withstand vibration of 5G at 10 to 500 Hertz. On the other hand, the Operating Shock it was tested for is 30G, and the Non-Operating Shock is 50G. In addition to this, the module comes with surge transient immunity, conducted RF immunity and EFT/B immunity. Designed to operate in an environment where temperatures range between 0 and 6 degrees Celsius (32 and 140 degrees Fahrenheit), the module can operate in an area with relative humidity between 5 and 95% non-condensing. Due to its capacity, the 1756-PB72 is not designed for use in a residential area as it lacks protection against radio communication services and may cause damage if used off industrial floors.
