4.2Operation in On-line Mode4.2.1Normal Operation

Normal AC source power is available, see Figure 4-5.

◗Lights 1 , 4 and 5 shine green on the control panel.

-The power necessary for the load is provided by the normal AC source (1) through the rectifier/charger (A) and the inverter (B). The rectifier/charger (A) also supplies the power to float charge and recharge the battery if any.

The output voltage (DC) is regulated to supply:

◗The float-charging or the recharging voltage for vented lead-acid or Ni/Cd batteries. - a single charge voltage for sealed lead-acid batteries.

The voltages depend on the number of battery cells and the battery manufacturer. Factory set, they may also be adjusted by support technicians.

An electronic board continuously measures the battery temperature and automatically adjusts the voltages.

NOTE	In parallel Galaxy PW™ systems, the power drawn by the load is equally shared
	between the different units.
