Twenty-two, the scope of application

1. Use as a normal blood pressure modules with overcurrent protection capability

How to use:

(1) This regulation potentiometer, the output voltage reaches the value you want

(2) 10A current with a multimeter measuring the output short-circuit current file (directly to the two can lead to the output), and adjust 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 the 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, causing cell damage, so start to the battery using a constant current charging, when charging to a certain extent when the automatic switch back to constant voltage charging.

How to use:

(1) Make sure you need to recharge the battery float voltage and charging current; (if lithium argument is 3.7V / 2200mAh, then float voltage is 4.2V, the maximum charging current of 1C, namely 2200mA)
(2) under no-load conditions, the multimeter to measure the output voltage adjustment potentiometer allows constant 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 can lead to the output), and adjust 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; (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 is off, the 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 drive 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.

(Step 2, 3 is: then the power input and output load is not connected LED lights.)
