DC Power Supplies

The DC inputs are located on the front of the power supply. Each set of power terminals on the DC
power supply consists of two 6-mm, metric-threaded, nickel-plated, brass studs that are centered 0.625
inch (15.86 mm) apart.
The earth ground studs extend 0.52 inch (13.2 mm) above the power supply faceplate; the set of positive
(+) and negative (–) studs extend 0.9 inch (22.9 mm) above the faceplate. The nickel plating on the studs
enhances conductivity and resists corrosion.
The input terminals are isolated from the ground terminals. The BlackDiamond DC power supplies
operate with DC input that can range from -42 to -70 V. Each DC power supply requires a dedicated
60 A service.
The DC power supply ships with the input lugs attached to the power supply, and the power supplies
slide in from the front of the chassis, as illustrated in Figure 100.
For centralized DC power connections, install only in a restricted access area.
