Configurations
The GPS 4827 is a 7-foot cabinet that can provide up to 1800 amps of DC power in single or multiple
cabinets. Shown in Figures 2-2, 2-3 and 2-4.
Cabinets can contain ac distribution, dc distribution, a battery connection panel, rectifiers, and a
system controller. Cabinets can also be ordered as rectifier only or distribution only cabinets.
Illustrations
Figure 2-3 shows how supplemental cabinets may be added to grow the system for more distribution.
The rectifier output buses are interconnected to permit the cabinet to share current and ensure
common voltage references for all system rectifiers. The total system ampacities must not exceed
1800A.
