Specification

The Allen-Bradley 1756-PH75 power supply is a cornerstone component for ControlLogix automation platforms, engineered to provide clean, regulated DC power to the backplane and connected modules. This AC-input unit is optimized for industrial environments where reliability and continuous operation are non-negotiable. It delivers a combined output of 7.5A at 5.1V and 3.6A at 24V, making it suitable for large chassis configurations with high I/O counts or communication modules. The 1756-PH75 supports redundant operation when paired with a second unit, ensuring seamless failover in critical processes. Its universal AC input range and integrated EMI filtering minimize electrical noise, while the diagnostic LEDs allow at-a-glance status monitoring. This module is fully compatible with all ControlLogix chassis (1756-A4, A7, A10, A13, A17) and meets global safety and emission standards.
