Voltage accuracy: ±0.5%+1 byte, resolution: 0.01V, factory calibrated accuracy
Current accuracy: ±0.8%+3 bytes, resolution: 0.001A, factory calibrated accuracy
Conversion efficiency: about 88%.
Soft Start:Yes.
Input Reverse Connection Protection: Yes, Reverse Connection No Burning
Output anti-backfilling: Yes, it can be directly connected to the battery.
Output Short Circuit Protection: Yes, it can be directly connected to the output terminal.
Temperature Protection (OTP): Yes, 100℃.
Working frequency: 180KHZ
After setting to CC, the constant current value is adjusted by default. When driving the LED, the fast dimming can be achieved by rotating the encoder, which is very convenient.
2. Setting up interface operation instructions:
2.1. Press the key of rotary encoder for 3 seconds to enter the setting interface.
2.2. By adjusting the parameters of the rotary encoded potentiometer, it can support fast rotation (fast increase/decrease), and switch the parameters to be adjusted by pressing the key of the rotary encoded potentiometer.
2.3. In the maximum capacity (OAH)/maximum energy (OPH)/maximum running time (OHP) interface, press the "ON/OFF" button to select the opening or closing of the corresponding function, and if it is closed, display "--";
2.4. In the maximum capacity (OAH)/maximum energy (OPH) parameter interface, long press the ON/OFF button to select the range of capacity (9.999Ah/99.99Ah/9999999Ah, 9.999Wh/99.999Wh/99999999Wh);
2.5. After the parameter setting, press and hold the encoder potentiometer key for 3 seconds to exit the setting interface and save the setting parameters automatically;
Note: After product protection, output will be turned off, LCD will display the corresponding protection code (LVP/OVP/OCP/OPP/OAH/OPH/OHP) power chip itself also has various protection, if the chip itself is protected, OEP will be displayed.
3. This product has locking function:
Press the code potentiometer button for 5 seconds, lock the set voltage and current, prevent misoperation! After locking, press the code potentiometer button for 5 seconds to unlock!
4. Product use method:
4.1. As a common boost-and-drop power supply with over-voltage/over-current/over-power/over-temperature/under-voltage protection;
(1) Setting the voltage value.
(2) Set the constant current value (overcurrent protection value); (For example, the constant current value is 3.00A, then the maximum current of your product can only reach 3A, when the current reaches 3A, the liquid crystal will display the "CC" state, otherwise the liquid crystal will display the "CV" state.)
4.2. Use as battery charger
Products without constant current function can not be used to recharge batteries. Because of the great voltage difference between batteries and chargers, the charging current is too large and the batteries are damaged. So the batteries should be charged with constant current at the beginning. When the charging reaches a certain level, the batteries should be automatically switched back to constant voltage charging.
(1) Determine the floating charge voltage and current of the rechargeable battery you need; (If the lithium battery parameter is 3.7V/2200mAh, the floating charge voltage is 4.2V, if it is 12V rechargeable battery, the floating charge voltage is generally set to about 14V).
(2) Under no-load condition, set the voltage value to make the output voltage reach the floating charge voltage; (If charging 3.7V lithium battery, adjust the output voltage to 4.2V only)
(3) Setting constant current value (charging current of battery) under no-load
