About the Protection for battery charger
Output Over Voltage Protection
When the charger output voltage exceeds the maximum charging
voltage, the charger enters the standby state protection. It will
restore to normal working condition automatically after
troubleshooting.
Output Over Current Protection
When the charger output current exceeds the maximum charging
current, the charger enters the over current protection status. It
will restore to normal working condition automatically after
troubleshooting.
Short Circuit Protection
When the charger has short circuit at output, the charger enters
short-circuit protection status. It will restore to normal working
condition automatically after troubleshooting.
Reverse Polarity Protection
When the charger output positive negative pole and battery pack are
connected in reverse, the internal relay of the charger is not
sucked and there is no voltage current at the output terminal of
the charger. After the correct connection, the charger can be
charged normally.
Over-Temperature protection
When charger internal temperature exceed 75℃, it will be Into the
over-temperature protection state and the cuts off output and the
cooling fan is still working. When the temperature returns to 65℃,
the charge is restored again
Advantages
1. AC input range selectable by switch.
2. Cooling by built-in DC fan, Ultra-silence without fan,
Waterproof for option.
3. LED indicator for charging status.
3. Multi-protection:short circuit,Over load,Over /Under voltage,
Over current, Over temperature,Reverse poloarity,Automatic
shutdown,Timing,Discharging.
4. 3-stage charging mode: CC, CV and float/trickle(or Cut off) .
5. Long lifetime: In the MTBF test, it makes more than 30,000
POH(power on hours) ,which means about 10 years if it work 8 hours
every day.
6. Led Meter available: Show Charging Voltage and Charging Current.
7. Efficiency: ≥ 93% (full capacity),high performance , stable and
durable .
8. Aluminum alloy shell: Good heat dissipation, anti-throw,
anti-seismic.
9. Automatic smart portable battery charger , easy to use and
convenience to carry
10.Low surge current,LLC resonance soft-switching
technology,sychronous rectification; no interference,low output
voltage ripple.
AC/DC plug choice
Many plug choice, for AC Plug: US, EU, AU,UK........
DC plug also have many choices: if u need others, we also can meet
it.
