The Allen-Bradley/Rockwell Automation 1771-P4SK power supply is a PLC 5 series power supply module. It is an AC power supply module that supports 120 Volts AC nominal input voltage and 97 to 132 Volts AC of operating voltage. The 1771-P4SK power supply module has a conformal coating which protects it from corrosive chemicals and moisture in its environment. This power supply weighs about 2 pounds and it is protected by a fuse. The 1771-P4SK power supply module can operate at 0 to 60 degrees Celsius or 32 to 140 degrees Fahrenheit with 5 to 95% non-condensing relative humidity.

The 1771-P4SK PLC 5 Conformal-Coated Power Supply Module by Allen-Bradley is a power supply module which is installed on a single 1771 I/O Chassis slot with a nominal input rating of 120V AC and supplies 5V DC output voltage to the chassis. Its input voltage ranges between 97 and 132V AC, and the module consumes 59W real input power with 89VA apparent power at 50 - 60Hz line frequency. The 1771-P4SK supplies 8A maximum current to the chassis to the backplane at 5V DC, and it dissipates 17W maximum heat with 10W on the adjacent slot. The module is fused with a 1.5A, 250V AC slow blow fuse, and it has a Terminal Block screw torque of 7 pounds-inches (0.5Nm). The 1771-P4SK has 2160V DC tested for 1-second voltage isolation, and the module’s circuit conductor is a 2.5mm2 (14 AWG) size copper wire rated at 60 degrees Celsius or greater, with 1.2mm (3/64 inches) maximum insulation.

It provides 15A branch circuit protection, and the module’s maximum power loss delay time between power loss to processor disable is 13.6ms (+-3.6ms). The 1771-P4SK has an IEC-tested working temperature range between 0 and 60 degrees Celsius (32 and 140 degrees Fahrenheit), around an ambient relative humidity range of 5-95% (without condensation), and it has a storage temperature range between -40 and 85 degrees Celsius (-40 and 185 degrees Fahrenheit). The module is keyed to the backplane through a connection between pins 12 and 14, 20 and 22 of the backplane connector, and it weighs approximately 1.04Kg (2.03lb).
