Marine Battery Charger BM1220B

Application:
Mainly used in fixed voltage and capacity of the battery power equipment, such as ships, cargo ships, fishing boats, yachts, naval vessels, electric boat, etc.

Model:

Features:
1. Ac input power a wide range
2. According to the battery charging curve design, charging efficiency is high, the battery plumpness can be as high as 97% above
3. Built-in miniature single-chip microcomputer, the switching power supply technology principle design, small size, easy to carry
4. All floating automatic intelligent conversion, no attendant, full of stop, to prevent the battery charging, prolong the service life of the battery
5. A variety of current specifications, can meet user requirements for charging time choice
6. The battery reverse connect protection, overcharge protection, short circuit protection, over current protection, overheating protection
7. Add salt fog, moisture-proof, prevent mildew anti-corrosion treatment
8. Constant current charging, constant current pulse charging, constant pressure pulse charging - floating - automatic shutdown

Operation method:
1) First pick the cell (pay attention to positive and negative polarity, please do not reverse connection! ,
connected to the alternating current (ac), and open charging machine
2) Close the power switch, the green light, fan began to turn, charging machine start charging
3) Green light normally on , charging machine to the battery constant current charging
4) Green light flashing, charging machine to the battery for pulse charging, charging quantity test condition
5) Yellow light, indicates that the battery into the floating charge state
6) After charging, charging state light put out, charging machine automatic stop work
7) Turn off the power switch, remove the battery over charge
