features:
It is charged in the daytime, automatically turns on the lamp at night, and automatically turns off the lamp at dawn. The output voltage is the output voltage when the battery has no voltage. The circuit controls the output by detecting the voltage change generated by the solar panel, and does not need photosensitive elements; It is suitable for all kinds of batteries.
Wiring mode:
1. B+B - Connect lithium battery
2. S+S - Connected to solar panel
3. L+L - output
Wiring:
1: To connect the lithium battery, the battery must have a corresponding protective plate
2: Connected to the LED, the lithium battery is powered on, and the LED lights up
3: Connect to the solar panel. At this time, the solar panel is illuminated by the light, the LED is off, and the LED lights up when there is no light.
If the switch needs to be closed at night or the switch interface SW has been reserved for transportation and storage, the switch can be installed.
matters needing attention:
1: The stable operating output current of the control board shall not be greater than 600ma, otherwise it may leads to output protection
2: Charging and anti backflow, no overcharge and over discharge protection The lithium battery must be used together with the corresponding protection plate (all mobile phone batteries have 3.7v protection, more than have no 3.7v protection plate can not be used in series)
3: Pay attention to waterproof and insulation
4: The LED lamp cannot use the boost drive
5: The battery voltage of the controller is the output voltage, without current and voltage restrictions. 2V3V LED lamp beads cannot be used directly. They need to be driven by step-down constant current or series current limiting resistors. The output current is the maximum working current, not the constant current
Special instructions:
1: The output power is the actual power. Please confirm the actual power consumption of the load before use
2: Direct contact with 3Vled may damage the controller or LED
3: The battery must be equipped with a protective plate, and the battery voltage must match the open circuit voltage of the solar panel
The package includes:
1 * Solar control switch circuit board
