3.7V Solar Lamp Circuit Board Controller 6V/12V Solar Lamp for Lawn Control Panel Spotlight Pole Lantern ControllerFeature:1. Overcharge protection.2. Over-discharge protection.3. Charging current le; 3A.4. Load current le; 1,1a.5. Output with self-regenerating fuse.6. Can be set to normally open or flashing7. The overall design of the low power circuit board.8. If necessary, you can adjust the time to turn off the light.9. 6V, 12V acid battery, 3.2V lithium iron battery, 3.7V.10 lithium battery can be used. Anti-interference function, lights on, strong light for about 5 seconds will not turn off the lights, 5 seconds after the lights go out11. Light control or can be set to light control, default light control, daytime charging, night auto lighting.12. Printed circuit board controlled by a single-chip computer to achieve small size and multi-function. Specification:Solar Lawn Lamp Circuit Board: Compatible with 3.7V lithium battery, 3.2V lithium iron phosphate battery, 6V12V realize-acid batteryCharging current: le; 3A Discharge Source: le; 1A PCB Measurement: 20mm * 35mm/0.79 * 1.38in Applicable Occasions:1. It can be used for solar warning lights, solar strobe lights, solar street signs, solar road signs, solar navigation lights and other places2. It can be used for solar garden lights, solar street lights, solar relays, solar monitoring, solar billboards, etc.3. This board does not have a light driving function. When a low-cost drive is required, the board can be replaced with a suitable resistor to drive the self-recovery fuse LED, but the following points should be noted: it must be controlled within 1.1A; Second, The power consumption and temperature rise of the current-limiting resistor should be controlled within a reasonable range. Battery by Environment: For 6V and 12V rechargeable batteries and 3.7V single cells lithium batteries, the board automatically determines according to the voltage. For 3.2V LiFePO4 batteries, the voltage coincides with 3.7V LiFePO4 batteries, so manual setting using 3.2V single-cell LiFePO4 batteries is required. Pcb. s2 short-circuit open-circuit point, which is equivalent to lead-acid 6V battery, lead-acid 12V battery and one 3.7V lithium battery, short-circuit protection suitable for one 3.2V lithium iron phosphate battery. By default, s2 is the open circuit state. This board only supports the above four types of batteries and does not support other types of batteries. If you want to use other types of batteries, be sure to adjust your hardware and software accordingly. Flash setting: S3 circuit board breaks for a long time, short circuit for flash. By default, s3 is open. Short circuit s3, the flashing frequency is about 1Hz. Light control settingDefault board:S1 in the power-on state, the light control function is effective, that is, charging during the day, automatically lights up at night. After a short circuit S1, the lighting control function is incorrect, i.e. Daytime Charging and Daytime Night LightingNote:Due to the different monitor and light effect, the actual color of the item may be slightly different from the color showed on the pictures. Please allow 1-2cm measurement deviation due to manual measurement.1 X Lawn Lamp Perimeter Control Panel
