Description
A-2000BC is an obligatory unit for the Va-2000MA voice evacuation system.It is used to work with battery to provide DC 24V power supply to the complete system,
thus the battery capacity shall be various from applications.
The VA-2000NC DC power supply and battery charger could work stand alone with any public address system as well.
There will be usually two units of 12V batteries cascaded together to output DC 24V for the system. It must have capacity to automatically
switched into DC mode to support at least 30 minutes of voice evacuation and standby 72 hours once AC power supply failed. While when AC backs, t
he battery automatically goes into charging mode. The battery capacity, temp and AC/DC failure all will be supervised and status displayed.
Features
* Option of automatical charge mode
* Repair of the battery overdischarge
* The detecting of battery failure, over input voltage, over temprature and overtime charging.
* Automatical temperature control fan and overheating protection
* The capacity of battery can be changed without being influenced by the input AC voltage.
