The X410R system accommodates 2 of the RANGER Series shelves with 4 rectifier modules in each for a total of 8 rectifiers, while the X610R increases this capacity by 50% to 3 shelves and a total of 12 rectifiers. The rectifiers are hot-swap for N+1 redundant operation, providing a high level of system security and ease of maintenance.
| Model | RRSI48/50-Z |
| DC Output Rating | 50A @ 54.4V |
| AC Input Rating | 230VAC – Operating range 170 – 264VAC |
The DC distribution panel includes DIN Rail mounted load circuit breakers for ease of changing in the field or adding as expansion demands. Also included are modular alarm cards for circuit breaker trip alarms, load shunts for sensing rectifier bus and load bus current, and a Low Voltage Disconnect (LVD) contactor to prevent deep discharge of the system battery.

Each of the 3 battery shelves in the cabinet is protected by a circuit breaker mounted on the front panel. External optional battery racks have individual breaker protection per shelf in its respective rack. Connection to these external racks is made via bus bar connections at the back of the cabinet with back panel removed.
| Rating | 125A |
| Alarm | Alarm contacts from CB to DSC1000 controller |
Input protection to each rectifier is provided via circuit breakers mounted on the front of the AC distribution panel. This panel also has a terminal block input to connect either a single phase or a 3 phase main feed plus ground.
