INTRODUCTION
| 1 | Big volume and high weight, not convenient for transportation and use |
| 2 | Lacking protection function, bad reliability |
| 3 | Must manual adjust charge current, difficult to full charge and avoid over charge the battery. |
| 4 | Silicon controlled rectifier adjusts the AC mains supply to charge battery directly. Then there is not isolation with AC mains supply which is dangerous to get an electric shock. And it will damage the AC mains supply waveform. |
| 1 | Short-circuit protection: output current will cut off automatically when short-circuit. |
| 2 | Overload protection: Output Current Will Be Limited Automatically When Overload. |
| 3 | Reverse polarity protection: it will shut down until fuse or the fault removed. |
| 4 | 2-stage charging mode: CC(Constant Current), CV(Constant Voltage) |
| 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 | All kinds of production has passed the CE certification and ROHS. |
| 8 | Aluminum shell:The charger body uses aluminum shell,convenient heat dissipation ,and is not easy to deform ,not easy to damage,give you a perfect apperance and use experience. |
| 9 | Automatic Fan Forced Ventilation Forced Ventilation helps to cool the charger in time |
| 10 | Note: The charger should be placed in good ventilation and free of flammable materials. |
About the plug of the charger
1) Error input voltage: Check if the input voltage conformed to the requirement or not.
2) Abnormal AC input: Check whether there is AC voltage and whether the input plug is loose.
3) Machine over heat: Check that the fan is running. Also pay attention to ventilation at the
working place of charger, covering anything on the charger is not allowed.
4) Output short circuit: Check the wire line of output terminal to exclude short-circuit.
5) No battery or reverse connection: Check the battery connection, connect the battery correctly.
6) Battery voltage is too low: Make battery voltage up to the starting voltage of charger.
