The Allen-Bradley 1771-PS7 is a stand-alone 120-220V AC Auxiliary Power Supply with a nominal input current/voltage of 2A at 120V AC and 1A at 220V AC. It has a frequency range of 4763Hz and an input voltage range of 97132V AC (120V) and 195264V AC (240V). Its backplane output is rated +5V DC at 16 A. The 1771-PS7 is part of the 1771 Power Supply series and it is compatible with PLC-5 Programmable Controllers and 1771 Control Systems.
Before connecting the External 1771-PS7 Auxiliary Power Supply to the backplane, mount the I/O chassis first. Set the configuration jumper to the N position, since the supply is stand-alone. It has a D-sub connector that provides power to the backplane. To avoid power supply overloading; limit the backplane power to 80W, or the user power to 65W, or limit the total system power (add backplane + user) to 100W.
The 1771-PS7 Module can be attached to the I/O chassis or mounted separately. When attaching to the panel-mounted chassis, make sure the mounting plate taper pins and supply receiving holes are aligned. Push until the power supply plug is fully inserted into the chassis receptacle. The 1771-PS7 can only be mounted next to or above the chassis. This arrangement allows convection cooling FOR both devices.
