INVERTER
A 3-phase PWM inverter is connected to batteries by a classic DC link.
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+
SA
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+
SA
cabinet. Batteries are charged by the rectifier, which supplies both the inverter and
the battery charger.
