Series ControlLogix
Allen-Bradley 1756-PBR2K is a conform-coated 1756 ControlLogix redundant DC power supply kit. It includes 2 redundant power supplies, 2 cables, and a case adapter. Compatible redundant power supplies include the 1756-PA75R and 1756-PB75R. The number of redundant power cables includes 1756-CPR2, 1756-CPR2D, and 1756-CPR2U. The 1756-PSCA2 is a redundant power chassis adapter. Redundant power systems are also available in XT versions for harsh and extreme environments.
The input voltage range of the redundant power supply is 18-32 V DC, and the nominal input voltage is 24V DC. It has a maximum input power of 110W at 0-60 °C (32-140 °F) and a maximum output power of 75W. Its current capacities are 1.5A (1.2V DC), 4A (3.3V DC), 13A (5.1V DC) and 2.8A (24V DC). It is installed in the left slot of the 1756 ControlLogix case and comes with an open case or no case. The cable features a 2.5 mm (14 AWG) solid or stranded copper wire rated at 90 °C (194 °F) or higher with a maximum insulation of 1.2 mm (3/64 in).
The 1756-PBR2K power supply kit is suitable for industrial environments with non-condensing relative humidity of 0-60 °C (32-140 °F), operating shock of 30 g and relative humidity of 5-95%.
