The Allen Bradley 1756-PBXTR  is a ControlLogix-XT Redundant Power Supply that includes control and communication system components that can be used with FLEX I / O-XT ™ products. Its dimensions are approximately 17.5 x 14.5 x 13.7 centimeters (6.9 x 5.7 x 5.4 inches) and it weighs approximately 1.45 kilograms (3.2 pounds). It comes with a current capacity of 10 A at 5.1 Volts.

This power supply is mounted on the Left side of a 1756 chassis; when installing the 1756-PBXTR, keep the wire lengths as short as possible to minimize resistance between chassis and ground connections. Leave 15.3 centimeters (6.0 inches) between the chassis and heat source, and 5.1 centimeters (2 inches) between the wireway and the top or bottom of the chassis. Chassis should be mounted only horizontally. Do not mount the chassis vertically.

The 1756-PBXTR  operates at temperatures between -25 to 70 degrees Celsius (-13 to 158 degrees Fahrenheit); while in storage, this unit can keep temperatures between -40 and 85 degrees Celsius (-40 and 185 degrees Fahrenheit). The maximum surrounding air temperature of this power supply is 70 degrees Celsius (158 degrees Fahrenheit). Its relative humidity is based on IEC 60068-2-30 of 5% to 95%, non condensing.

This unit has an operating vibration of 2 G at 10 to 500 Hertz; its operating and nonoperating shocks are 30 G and 50 G respectively.
