1768-PA3

The Allen Bradley 1768-PA3 is categorized as a power supply module within the CompactLogix series. It accommodates a voltage range of 120/220V AC, with operational capabilities extending from 85 to 265 volts AC and 108 to 132 volts DC. This broad voltage acceptance ensures compatibility across multiple environments.

The unit typically achieves 75% efficiency, providing reliable performance with minimal energy loss. Unlike many power supply modules, the 1768-PA3 has an open-style design, foregoing a traditional enclosure, which may facilitate easier integration in specific setups.

Engineered to handle input frequencies from 47 to 63 hertz, this device is rated for a maximum input power of 120 VA or 120 watts. The maximum power dissipation reaches up to 30 watts, indicating its capability for managing heat generation under load. Overcurrent protection is implemented through a soldered, non-replaceable fuse, adding an element of safety in use.

Wiring the device requires attention to the specified conductor screw torque of 0.6 Nm and must operate within a wiring category of Category 1 at its power ports. Moreover, it is rated to endure shocks of up to 30 g, ensuring durability in rough operating conditions. The 1768-PA3 power supply module serves as an essential component for various automation applications within the Allen Bradley CompactLogix framework.
