Allen-Bradley 1756-PB72 ControlLogix Power Supply

Description

The Allen-Bradley 1756-PB72 ControlLogix Power Supply is an AC power module engineered for the ControlLogix automation system, designed to deliver stable, clean power to chassis-mounted controllers, communication modules, and I/O modules. It features a wide input voltage range of 85 to 265 VAC (compatible with 120/240 VAC inputs) and a frequency range of 47-63 Hz, making it adaptable to fluctuating industrial power conditions. With a rated output power of 72 watts, it provides sufficient power for medium-scale ControlLogix rack configurations, delivering specific DC outputs: 4A at 3.3VDC, 10A at 5.1VDC, and 2.8A at 24VDC to support system components. Key technical features include high reliability via industrial-grade components, and comprehensive protection mechanisms such as overvoltage, undervoltage, overcurrent, short-circuit, and overheating protection to prevent system damage during abnormal operation. Its chassis-mounted design enables easy installation and maintenance, while high-efficiency operation reduces heat generation for prolonged performance. Ideal for industrial automation applications, it is widely used in manufacturing, energy, transportation, and other sectors that demand robust, consistent power for control systems.
