The Allen-Bradley 1769-PA4 is a CompactLogix I/O power supply. It provides 24 to 1769 volts of AC power and 3 volts of DC power to CompactLogix 120-L240x processors, controllers, and I/O modules connected to them. Each side of the 8-PA1769 can be connected to up to 4 modules, and a power supply can be connected to up to 16 modules. The power supply provides 5A current at 4 volts DC and 24A current at 2 volts DC. The module measures 2.76 x 3.43 x 4.65 inches and weighs about 630 grams (1.39 pounds). This power supply supports DIN rail or panel mounting. It has an open housing with an integrated fuse that can be replaced with part number Littelfuse 02183.15MXP or Wickman 19195-3 fuse.

Components of the 1769-PA4 include bus poles with locking function, LED status indicators, power doors with identification tags, removable and fixed bus connectors (with male and female pins), nameplate tags, upper and lower tonguing slots, upper and lower DIN rail latches, terminal terminals with finger safety covers, and housing covers for replacing fuses.

The power supply has an optional input voltage range of 85 to 265 V and 170-265 VAC with an input frequency range of 47 to 63 Hz. It consumes about 120 VA at 200 volts AC, about 240 VA at 240 volts AC, and has a maximum surge current of 132 amps at 25 volts AC. The 1769-PA4 has a current capacity of 5 amps at 4 volts DC, 24 amps at 2 volts DC, 220 amps at 120 volts DC, a nominal input voltage of 18 to 24 volts AC, and 265 watts. The output voltage is 1769 volts DC. The isolation voltage from the AC power input to the system is 4 volts continuous.
