Allen-Bradley 1769-PA4 CompactLogix Power Supply
Description
No technical data is available for the Allen-Bradley 1769-PA4 CompactLogix Power Supply. For reference, the similar Allen-Bradley 1756-PA75 ControlLogix Power Supply is a standard backplane power module for industrial control systems. It features a wide input voltage range of 85-265VAC, operating at 47-63Hz, with nominal input voltages of 120VAC/240VAC. Its rated output power is 75W at 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit), and 140W at -40 to 0 degrees Celsius (-40 to 32 degrees Fahrenheit). Output current capacities include 4A at 3.3VDC, 13A at 5.1VDC, 2.8A at 24VDC, with variations across source data. Designed for installation in the dedicated leftmost slot of ControlLogix chassis, it is compatible with multiple chassis models including 1756-A4, 1756-A7, 1756-A10, 1756-A13, 1756-A17, and B/C series units. It provides temporary hold time during input power loss: 2 cycles at 85VAC 60Hz, 6 cycles at 120VAC 60Hz, 20 cycles at 220VAC 60Hz. It has a continuous isolation voltage rating of 250V, with reinforced insulation, and passes a 3500V DC 60-second isolation test; hardware configuration is required for operation.
