Optical Induction Module Kit

Product Information:

Black technology! Automatic charging during the day and automatic lighting at night!

The effect of using photosensitive resistor is much better than that of photosensitive control: many friends are asking you why there is no photosensitive element (photosensitive resistor) in this control panel. This panel is used to charge lithium battery and also as photosensitive element to control the output according to the solar panel, realizing automatic charging in the daytime and automatic lighting in the dark at night.

This control panel is adaptive to 4.2v (3.7), 8.4v (7.4), 12.6v (11.1), 16.8v (14.8) lithium battery with protection circuit

Parameters:

● Solar panel power: ≤ 10W/≤ 12W ≤ 15W ≤ 20W

● Open circuit voltage: 5-7V/9-14V/18-22V/20-26V

● Working voltage: 4.2V/8.4V/12.6V/16.8V

● Working current: ≤ 1.5A/≤ 1.5A/≤ 1.5A/≤ 1.5A

● Number of lithium battery strings: 1/2/3/4

● Total voltage of lithium battery: 3.7V/7.4V/11.1V/14.8V

● Output current of control board: ≤ 1.5A/≤ 1.5A/≤ 1.2A/≤ 1A

● Output power: ≤ 5W/≤ 10W/≤ 12W ≤ 15W

Scope Of Application:

Charging and automatic switch control of low-power solar energy application products such as solar garden lamp, lawn lamp string, DIY street lamp

Be Careful:

1. The stable output working current of the control board shall not be greater than 1.5a;

2. The lithium battery must be used independently with a protective plate to prevent charging, backflow and overcharge;

3. The battery voltage of this board is the output voltage infinite current limit voltage;

4. LED lamps can not be driven by boost voltage, and LED lamp core or bead can not be used directly, which requires step-down drive or series current-limiting resistor (for example, the common 1w LED lamp bead requires that the working current of 3-3.3v is 300-350ma for 3.7v lithium battery, which requires step-down drive or series of about 4-15 Ω high-power resistance current-limiting).
