Function description: After the power is connected, the left and right two red LED (can be replaced by other color LED) flicker alternately, so anti
Multiple cycle, the higher the power supply voltage, the brighter the LED, changing the electrolytic capacitor capacity can change the speed of alternating flashing, the greater the capacity, flashing
The slower the blinking speed is, the smaller the capacity is and the faster the blinking speed is. The circuit is simple and easy to understand, the solder pad has been done with tin spraying process, welding is easier, welding
Point more beautiful! Especially suitable for friends and students who are beginning to learn electronics.
 
Circuit principle:
When the power supply is switched on, two triodes must compete for the pilot, but due to the differences in components, only a certain pipe pilot. If Q1 is on, then Q1 collector voltage drops, D1 is lit, and the left end of capacitor C1 is close to zero voltage. Since the voltage at both ends of capacitor cannot change suddenly, Q2 base is also pulled to nearly zero voltage, so that Q2 is cut off and D2 is not bright. As the power supply charges C1 through the resistor R2, the base voltage of the transistor Q2 gradually increases. When the voltage exceeds 0.6V, Q2 changes from the cut-off state to the conduction state, the collector voltage drops, and D2 is lit. At the same time, the decrease of collector voltage of transistor Q2 makes the base voltage of transistor Q1 jump down through the action of capacitor C2, Q1 changes from conduction to cut-off, and D1 goes out. In this way, two transistors in the circuit will take turns to conduct and stop, and two light-emitting diodes on the cycle of light. Changing the capacity of the capacitor can change the speed of the LED cycle.

Second, the application
1. Use as a normal blood pressure modules with overcurrent protection capability
Instructions:
(1) constant pressure regulator potentiometer, the output voltage reaches the voltage value you want
(2) 10A current with a multimeter measuring the output short circuit current file (directly to the two leads to the output can), while adjusting the constant current potentiometer allows the output current reaches a predetermined value of overcurrent protection. (Such as the current value of the multimeter displays 4A, then you can use the module to the maximum current 4A, 4A current to constant voltage constant current when the red light is on, otherwise the light off)
Note: When used in this state, since the output of 0.05 ohm current sense resistor, there will be 0 ~ 0.3V voltage drop after connected to the load, this is normal! This drop is not being pulled down your load, but down-sampling resistor.
 
2. Use as a battery charger
Module without constant function can not be used to charge the battery, since the end of the battery and charger power consumption big difference between charging current is too large, resulting in damage to the battery, so when you want to start the battery using a constant current charging, when charging to a certain extent automatically switches back to constant voltage charging.
Instructions:
(1) Make sure you need to recharge battery float voltage and charging current; (if lithium argument is 3.7V / 2200mAh, then float voltage is 4.2V, the maximum charging current 1C, namely 2200mA)
(2) under no-load conditions, the multimeter to measure the output voltage of the constant voltage potentiometer to adjust the output voltage reaches the float voltage; (if rechargeable lithium battery to 3.7V, the output voltage can be adjusted to 4.2V)
(3) 10A current with a multimeter measuring the output short circuit current file (directly to the two leads to the output can), while adjusting the constant current potentiometer allows the output current reaches a predetermined charge current value;
(4) Charging turn lamp current default factory setting is 0.1 times the charging current; (the battery during charging current is gradually reduced, gradually converted to constant voltage charging by the constant current charging, if the charging current setting is 1A, then when Charge current is less than 0.1A when the blue light off, green light is on, then the battery is fully charged)
(5) connected to the battery charge.
(1,2,3,4 step is: input termination power, output unloaded battery is not connected)
 
3. Use a high-power LED constant current driver module
(1) determine the work you need to drive the LED current and the maximum operating voltage;
(2) No-load condition, the multimeter to measure the output voltage of the constant voltage potentiometer to adjust the output voltage reaches the LED maximum working voltage;
(3) 10A current with a multimeter measuring the output short-circuit current gear while adjusting the constant current potentiometer allows the output current reaches a predetermined LED working current;
(4) connected to the LED, the test machine.
(Steps 1 through 3 are: input connected to the power supply, the output load is not connected LED.)
 
Note: This module is more than 3A, 35W in use, to enhance heat dissipation! ! !
