Charger directly uses 220V AC power supply. It achieves the output voltage adjustment starting from 0V by controlling the triggering circuit. It is suitable for charging 12V-220V battery (s). The main control circuit is composed by the fuse FU, ammeter and SCR VS. When the battery, as well as the batteries, requiring being charged is connected, the SCR VS gains trigger pulse. Conduction angle of VS is regulated by pulses with different width. And the RP can be adjusted to meet the charge of different battery or batteries within different charging current or voltage.
