Product Highlights:
1. Digitally adjusted voltage and current, convenient and fast, industrial quality, high precision, can be directly used in engineering projects;
2. Using professional power LCD, the interface is clear, the operation is very simple, and it has a nearly perfect protection mechanism;
3. Hardware protection: input terminal anti-reverse protection, reverse connection does not burn; output terminal short circuit protection, short circuit does not burn; output terminal is anti-reverse, no additional anti-reverse diode is required when charging the battery;
4. Software protection: overvoltage protection (OTP), overcurrent protection (OCP), overpower protection (OPP), overtemperature protection (OTP), input undervoltage protection (LVP);
5. The default adjustable voltage or constant current value can be set, which can be quickly adjusted in various applications;
6. Voltage and current can be locked to prevent misoperation!
7. Full of materials, stable performance and wide range of uses.
1.Product parameters:
Input voltage: DC6.0V-36V (under-4.7V has undervoltage protection LVP, it is recommended to use the input voltage higher than 7V, when the input voltage is lower than 7V, the output power will be reduced, the lower the input voltage, the smaller the output power)
Output voltage:DC0.6V-36V
Output current:0-5.100A
Output power: under natural heat dissipation 80W
Voltage accuracy: ±0.5%+1 byte,Resolution:0.01V,Factory calibrated accuracy
Current accuracy:±0.5%+3 bytes,Resolution:0.001A,Factory calibrated accuracy
Conversion efficiency: about 88%
Soft start: Yes
Input reverse connection protection: Yes, reverse connection does not burn
Anti-backflow at the output: Yes, can be directly connected to the battery
Output short circuit protection:Yes, the output can be shorted directly
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 code positioner, which is very convenient!
2. Operation instruction of setting interface:
2.1. Press and hold the rotary encoder button for 3 seconds to enter the setting interface;
2.2. Adjust the size of the parameter by rotating the coded potentiometer, support fast rotation (fast increase / decrease), short press the rotary potentiometer button to switch the parameter to be adjusted;
2.3. On the maximum capacity (OAH) / maximum energy (OPH) / maximum operating time (OHP) interface, short press the "ON / OFF" button to select the corresponding function to turn on or off, if it is turned off, it displays "----" ";
2.4. In the maximum capacity (OAH) / maximum energy (OPH) parameter interface, long press the "ON / OFF" button to select the capacity range (9.999Ah / 99.99Ah / 999.9Ah / 9999Ah, 9.999Wh / 99.99Wh / 999.9Wh / 9999Wh );
2.5. After the parameter setting is completed, press and hold the encoder potentiometer button for 3 seconds to exit the setting interface, and the setting parameters are automatically saved;
3.This product has a lock function:
Press and hold the coding potentiometer button for 5 seconds to lock the set voltage and current to prevent misoperation! After locking, press and hold the code potentiometer button for 5 seconds to unlock!
4.Applications:
4.1. Used as a common buck-boost power supply with overvoltage / overcurrent / overpower / overtemperature / undervoltage protection;
(1) Set the voltage value.
(2) Set the constant current value (overcurrent protection value); (For example, the set constant current value is 3.00A, then the maximum current when you use the product can only reach 3A, and the LCD will display "CC" when the current reaches 3A Status, otherwise the LCD displays "CV" status)
4.2. Use as a battery charger
Products without the constant current function cannot be used to charge the battery. Due to the large voltage difference between the exhausted battery and the charger, the charging current is too large and the battery is damaged. Current charging, when the charging reaches a certain level, it will automatically switch back to constant voltage charging.
(1) Determine the float charge voltage and charge current of the rechargeable battery; (if the lithium battery parameter is 3.7V / 2200mAh, then the float charge voltage is 4.2V, if it is a 12V rechargeable battery, the float charge voltage is generally set 14V or so)
(2) Under no-load conditions, set the voltage value so that the output voltage reaches the float charge voltage; (if the 3.7V lithium battery is charged, adjust the output voltage to 4.2V)
(3) Under no-load conditions, set a constant current value (battery charging current);
(4) Connect the battery and charge.
4.3. Use as LED constant current driver
(1) Determine the working current and maximum working voltage of the LED you need to drive;
(2) Under no-load conditions, set the voltage value and current value so that the output voltage reaches the maximum working voltage and current of the LED;
(3) Connect the LED and test the machine.
This product can realize the stepless dimming of LED by adjusting the constant current value (between 0-working current), without strobe! !
5. Detailed function
5.1 Capacity / energy / run time statistics:
The statistics are automatically started after the power is turned ON. The value of the last state is displayed after the power is turned OFF. The recording is automatically restarted after the power is turned ON again. On the corresponding interface, long press the ON / OFF button for 3 seconds The corresponding data is automatically cleared.
5.2 Set maximum capacity / maximum energy / maximum running time
5.2.1. Set the maximum capacity (OAH) / energy (OPH): When the OAH / OPH function is activated, when the statistical capacity / energy is higher than the set maximum capacity / energy, the power will automatically turn off the output and flash "OAH" / 'OPH' ; After the alarm is lifted, the capacity / energy statistics are automatically cleared;
5.2.2. Set the maximum discharge time (OHP): When the OHP function is activated, when the power supply running time is greater than the set maximum discharge time, the power supply automatically turns off the output and flashes "OHP"; after the OHP alarm is released, the time statistics are automatically cleared;
This function can achieve quantitative / timed power supply well.
Note: When the OAP / OPH and OHP functions are not turned on, the power supply will automatically record the capacity / energy and running time. After the OAH / OPH and OHP functions are turned on, the power supply automatically turns off the output after reaching the set value; The running time is in countdown mode;
6. Precautions:
6.1. Module input VIN- prohibited and output OUT- short circuit, otherwise the constant current function is invalid.
6.2. Please ensure that the power of the power supply is always greater than the power required by the output load!
6.3. If the product wants to output at full load, the input power should be 15V ~ 36V, the power is above 100W, the lower the input voltage, the smaller the output power, the limit on the input current: maximum 7A, more than 7A, the product will not be able to run for a long time.
6.4. The module has an input undervoltage protection function. The default is about 4.7V. When it is lower than this value, the output will be automatically disconnected. When the voltage is higher than 4.7V,
the output will be automatically restored. When the input current is relatively large, do not ignore the partial voltage on the input wire)
