The GX2-PSAC and GX2-PSDC modules are installed in the rear of the Omnistar GX2 Housing (GX2-HSG) where power connections are easily made. Integrated fans provide localized cooling. A tri-colored LED on the rear of the unit indicates operating status. An additional tri-colored status LED is provided for each power supply on the front of the Control Module (GX2-CM100B). Though on ower supply can power an entire housing, the GX2-HSG accommodates two power supplies for true power source redundancy. When two power supplies are used, the load is shared between both supplies. If one supply fails, the other immediately picks up the additional load. For increased flexibility, the second power supply can be either AC or DC depending on system needs.
