1. OVERVIEW
Fit with up-to-date power supply device, float charger BAC4812-KP is specially designed for meet the
charging characteristics of the lead-acid engine starter batteries and can be used for long-term float
charging of 12V lead-acid batteries. The maximum charging current is 3A.
2. PERFORMANCE AND CHARACTERISTICS
1) Switch power supply structure, wide input alternating voltage range, small size, light weight, high
efficiency rate;
2) Automatic two-stage charging process (first constant current, then constant voltage) carried out
according to storage battery charging characteristics to prevent overcharging and significantly
prolong battery lifetime;
3) With auxiliary voltage output port. Firm voltage output: -12V.
4) +12V output has current protective circuit for short-circuit protection and reverse connection
protection.
5) -12V output has short-circuit self-recovery function.
6) Both charging voltage and current value can be regulated by potentiometer on the spot;
7) LED display: Power indication (Green light) and charging indication (Red light).
