Dual-channel Fast Charger
Max charging current: 6A
S-3812S can charge 2 V-mount batteries simultaneously at Max 6A fast charging current, to SWIT over 160Wh capacity batteries. The charging speed is quite faster than normal chargers.
And for other batteries, the charging current is limited to 3A.


Charging time comparation


AC-DC Adapting Output
S-3812S supports 1-ch AC-DC adapting output via 4-pin XLR port. By S-7102 (4-pin XLR female to male) cable, it can supply 16.8V DC
power to the other equipments, Max load 200W/12A.
When adapting load is less than 100W, S-3812S can still charge battery simultaneously. (2 batteries sequential)
Remark: S-7102 cable is optional purchased.


Battery-DC Adapting Output
You can also mount batteries onto S-3812S, and output DC power via 4-pin XLR port. By S-7102 (4-pin XLR female to male) cable, it
can supply 16.8V DC power to the other equipments, Max load 200W/12A.
Remark: S-7102 cable is optional purchased.


LCD Charging Info Display
S-3812S has an LCD screen to display the real time charging/adapting
information, includes:
Battery Charging/Discharging status
Real time capacity and percentage
Real time Voltage/Current
Remaining time to fully charged
Remaining time to fully discharged
Battery cycle times
Adapting output current and power
Remark: The battery info display only available with digital Li-ion batteries: PB-H, PB-R, PB-S, PB-M series. For other non-digital batteries, the charger will only display
real time voltage and current.


3-color LED Indicators
S-3812S has the 3-color LED indicators for both 2 channels:
Red light slowly flashes: The battery is charging
Red light fast flashes: The battery is about to fully charged
Green light constant: The battery is fully charged
Green light flashes: The battery is adapting output
Orange light flashes: Battery or Charger abnormal alert
