产品介绍
The Allen-Bradley 1756-PA72K ControlLogix AC Power Supply is a reliable and widely used power module designed to provide stable backplane power for ControlLogix automation systems. With a standard 72 W output capacity, it ensures consistent and efficient power delivery to controllers, I/O modules, and communication modules installed within the chassis.
This 件 accepts a wide AC input voltage range / 85–265 VAC, making it suitable for global industrial applications without requiring additional voltage conversion. It delivers a regulated 5 VDC output at up to 10 A, along with additional current capacity for other backplane voltage rails, ensuring proper operation / all installed modules.
The 1756-PA72K is chassis-mounted on the left side and connects directly to the backplane, simplifying installation and improving system integration. Its open-style design enhances heat dissipation, while built-in status LEDs provide clear diagnostics for power conditions. The conformal coating further protects the module in harsh industrial environments.
