Key Description

Short press the UP/DOWN button, the voltage is adjusted by default, and long press (rapid increase/decrease) is supported; Long press the SET button for 1 second to adjust the constant current value (current limit value); SET and CV flash when adjusting the voltage, and SET and CC flash when adjusting the current, which is very intuitive; Short press the SET button to switch and display current A/power W/capacity Ah/energy Wh/time h; Short press the ON/OFF button to turn on/off the power output; Long press the ON/OFF button for 2 seconds to switch the display of input and output voltage.

Feature

1. Numerically controlled voltage and current adjustment, convenient and fast, industrial quality, high precision, can be directly used in engineering projects; 2. Using professional power LCD, clear interface, minimalist operation, and almost perfect protection mechanism; 3. Hardware protection: the input terminal is protected against reverse connection, and the reverse connection will not burn; the output terminal is short-circuit protected, and the short circuit will not burn; the output terminal is anti-backflow, and there is no need to add an anti-backflow diode when charging the battery; 4. Software protection: over voltage protection (OTP), over current protection (OCP), over power protection (OPP), over temperature protection (OTP), input under voltage protection (LVP); 5. The default adjustment voltage or constant current value can be set, which can be adjusted quickly in various applications; 6. Voltage and current can be locked to prevent misoperation! 7. Full materials, stable performance and wide range of uses.

This product has a lock function

Long press the SET button for 5 seconds to lock the set voltage and current to prevent misoperation! After locking, press and hold the SET button for 5 seconds to unlock!

Application

1. Use as an ordinary 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, when the current reaches 3A, the LCD will display "CC" Status, otherwise the LCD displays "CV" status) 2. Use as a battery charger Products without constant current function cannot be used to charge the battery. Because the voltage difference between the drained battery and the charger is large, the charging current is too large and the battery is damaged. Therefore, the battery must be constant at the beginning. Current charging, when the charging reaches a certain level, it will automatically switch back to constant voltage charging. (1) Determine the float voltage and charging current of the rechargeable battery you need; (If the lithium battery parameter is 3.7V/2200mAh, then the float voltage is 4.2V, if it is a 12V rechargeable battery, generally set the float voltage to Around 14V) (2) Under no-load conditions, set the voltage value to make the output voltage reach the float voltage; (if charging a 3.7V lithium battery, adjust the output voltage to 4.2V) (3) Under no-load conditions, set the constant current value (charging current of the battery); (4) Connect the battery and charge it. 3. Use as LED constant current driver (1) Determine the operating current and maximum operating voltage you need to drive the LED; (2) Under no-load conditions, set the voltage value and current value to make the output voltage reach the highest LED working voltage and working current; (3) Connect the LED and test the machine. This product can adjust the constant current value (between 0 and working current) to realize the stepless dimming of the LED without flicker! !

Detailed function

1 Capacity/energy/run time statistics: The statistics will start automatically after the power is turned on (ON), the value of the previous state will be displayed after the power is turned off (OFF), and the recording will be restarted automatically after the power is turned on again (ON); in the corresponding interface, long press the ON/OFF button for 3 seconds. The corresponding data is automatically cleared. 2 Set maximum capacity/maximum energy/maximum running time 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 supply will automatically turn off the output and flashing display "OAH" /'OPH'; After the alarm is removed, the capacity/energy statistics data will be automatically cleared; 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 will automatically turn off the output and flashing "OHP"; after the OHP alarm is removed, the time will be cleared automatically Statistical data;
This function can well realize quantitative/timing power supply. 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 will automatically turn off the output when the set value is reached; when the OHP function is turned on, the power supply The running time of is in countdown mode;

Matters needing attention

1. Module input VIN- must not be short-circuited with output OUT-, otherwise the constant current function will fail. 2. Please ensure that the power of the power supply is always greater than the power required by the output load! 3. If the module wants to output at full load, the input voltage must be above 8V, when the input voltage is 5V, the output power is about 15W; the maximum current value of the module is 4A, provided that the maximum output power is limited, for example, the output of 18V, the current should not be greater than 2A . 4. The module has an input under-voltage protection function. The default is about 4.7V. When the value 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 (Note: 4.7V is the voltage at the product port , When the input current is relatively large, do not ignore the voltage division on the input wire).
Installation Instructions

Setting interface operation instructions

2.1. Long press the SET button for 3 seconds to enter the setting interface; 2.2. Adjust the size of the parameter through the UP/DOWN button, support long press (fast increase/decrease), short press the SET button to switch the parameter to be adjusted; 2.3. In the maximum capacity (OAH) / maximum energy (OPH) / maximum operating time (OHP) interface, short press the "ON/OFF" button to select the corresponding function on or off, if it is off, it will display "---- "; 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.
