Adopting MCU (micro control unit) system,switch mode design and reverse pulse technology, the chargers are more compact, reliable and advanced. The most important is the reverse pulse high technology.
1.Switch Mode Design
Or we call Switching Power Supply, this is different from Linear Power using in traditional charger
1. Conversion efficiency:
More than 85% electric energy was transferred to battery chemical energy during charging process comparing with 40% of conventional charger.
2.Suitable for all types of batteries (wet, maintenance free, VRLA, AGM, etc)
2.Smart MCU System
Stop working by display END automatically when battery is full, however keeping monitoring battery status and automatic restart with pulse current to replenish when detect voltage drop.
3.Reverse Pulse Technology
Combined with MCU system, chargers generate reverse pulse current during the charging process.
1 Reducing battery internal impedance, gassing and temperature rise
2 Restore the sulfate into liquid to recover battery capacity.
3 Maintain battery, extend battery' service life and keep battery in good shape.
This will helps you to cut considerable costs on battery maintenance.
4.Protective Function
1.Reverse polarity and output short circuit protection.
2.Overload protection.
5.Digital Display
Digital Voltmeter, Ammeter and thermometer will show battery's voltage, current and temperature.
6.CE Certification
