AC/DC POWER SUPPLY
BatteryPlus35 provides an isolated output for powering of the loads and charging of the battery. It
enters into power supply mode if it is set to charge a lead-acid battery and is powered by AC mains
without the battery, providing an output voltage of 12.8V.
When a battery is detected, Battery current is sensed and monitored by the power supply to limit the
charging current. Refer to Charging Profile on page 26 for more details.
