Power Supply Capacity and Input Requirements
The 1769-PB2 accepts DC input within a range of 19.2-31.2 VDC. Its output capacity includes 2.0 A at 5 VDC and 0.8 A at 24 VDC. Therefore, equipment selection should account for both output ratings rather than treating the supply as a single-output 24 VDC source.
Furthermore, the maximum inrush current reaches 30 A when the input voltage is 31.2 VDC. This value is relevant when checking the upstream DC supply and protective device ratings.
Wiring Requirements
The power supply supports both solid and stranded conductors. The specified wire sizes are 22 to 14 AWG for solid wire and 22 to 16 AWG for stranded wire. Meanwhile, the actual conductor selection should also account for the installation requirements and applicable electrical standards.
