- Load setting: ± 1%
- Voltage regulation: ± 0.5%
- Current Accurac and temperature: Actual Testing, changes of temperature from 20 degrees to 100 degrees, constant current value variation Less than 1% (constant current value 1A)
- Response speed dynamic: 5% 200uS
- Direction of adjustment of the potentiometer: clockwise (increase), anticlockwise (decrease)
- LED indicator: red charging LED, green charging full LED
- Output short circuit protection: YES
- Input reverse polarity protection: YES
- Corruption prevention Outgoing body: YES
Method of use
- 1.Check the charging voltage of the charging battery and the charging current, the input voltage of the module
- 2. adjust the constant voltage regulator, the output voltage about 3V
- 3. With a multimeter (at 10A) measure the output short-circuit current, also adjust the constant regulator that allows the output current to obtain a predetermined charge current value
- 4. Adjusting the constant regulator allows the output voltage to get the floating voltage
- 5. Connect the battery and try to charge
NB (In the first 4 steps connect the power but not the battery, connect it in the fifth step)
