2.2 System Components
The AMPS80 HP consists of a number of individual subsystems designed to work together to provide highly
reliable, filtered power in support of the load. A typical system contains the following:
1. Main Wiring Access Panel: AC input and output as
well as Safety Extra-Low Voltage (SELV) DC battery
connections are accessed through the front panel and
fed through the opening at the top of the rack.
2. Rectifier AC Input Breakers (optional): Provide a
means to switch off the rectifiers independently of the
inverters.
3. Inverter AC Input Breaker: Serves as the main
disconnect for the inverter AC input.
4. Maintenance Bypass Switch (MBS) (optional): Can
be used to route power directly from the AC input to
the AC output, bypassing the inverter modules.
5. Inverter AC Output Breaker: Serves as the main
disconnect for the inverter AC outputs.
6. CXC Unified System Controller with integrated
Ethernet/ SNMP: Monitors and manages both
inverter and rectifier modules through a web-based
GUI and local LCD touch screen. This is a SELV
controller.
7. DC Input Breakers (optional): Provide SELV DC
power to each Inverter module.
8. T2S Inverter Control Card: Communicates with the
CXC Unified controller. This is a SELV Controller.
9. Inverter Modules and shelves: Up to 9 shelves
containing 4 hot-swappable 2500 VA / 2000 W inverter
modules on each shelf.
10. Rectifier Modules and shelves (optional): Two
shelves contain up to four hot-swappable 1800 W
rectifier modules on each shelf. The rectifiers are used
as the SELV DC battery charging component of a
hybrid system.
Each rectifier shelf is only connected to one of the DC-
battery feeds: the top shelf to DC1, and the bottom
rectifier shelf is connected to DC4. In a system with
four independent battery feeds, two of these battery
banks will not be charged from the AMPS80 HP
rectifiers.
