The Allen-Bradley 1756-PA72 power supply is expertly designed for the ControlLogix platform, providing reliable power to the backplane of a 1756 chassis, and supporting modules with an input range of 85-265 VAC at 47-63 Hz. This unit delivers robust performance with an output of 75 watts, offering current capacities of 4A at 3.3VDC, 10A at 5.1VDC, and 2.8A at 24VDC, and is ideal for installation at the left-most position outside the chassis without occupying a ControlLogix slot. With reinforced insulation tested at 3500 Volts DC for 60 seconds, and built-in overcurrent protection, the 1756-PA72 ensures safe operation, although it must be housed within an enclosure to guard against industrial contaminants.
