STATIC SWITCH (ST/SW)
The static switch enables an automatic transfer of the load from the output of the inverters to an alternate
source whenever the inverter can no longer supply power to the load. The static switch transfers current at
high speed.
BATTERY
The
POWER+ PREMIUM SA 15
battery bank is used as a backup in the event that the utility ac input fails.
The batteries are housed in an external cabinet next to the
POWER+ PREMIUM SA 15
cabinet. Batteries
are charged by the rectifier, which supplies both the inverter and the battery charger.
