(2) Adjust the right button so that Digital meter shows the value of output current;Wire shorted output terminal, then adjust thecurrent potentiometerso that the output current reaches a predetermined overcurrent protection value. (For example, the Digital meter displays the current value of 4A, then you can use the module to a maximum current of 4A) (3) Connected to the load. 2.Use as a battery charger Usage: (1) Make sure you need to charge the battery float voltage and charging current; (if lithium parameters 3.7V/2200mAh, then the float voltage is 4.2V, the maximum charging current 1C, ie 2200mA) (2)Under no-load conditions, adjust theVoltage potentiometerso that the output voltage reaches the float voltage; (if to 3.7V rechargeable lithium battery, the output voltage can be adjusted to Specification: Size: 51 * 26.3 * 14 (L * W * H) (mm) Operating Temperature: -40 ° to +85 ° Voltage Regulation: ± 2.5% Load Regulation: ± 0.5% Output ripple: 50mV (max) 20M bandwidth Switching frequency: 300KHz Conversion efficiency: 95% (the highest) Output current: adjustable maximum 5A Output voltage: 0.8V-30V Input voltage: 5V-32V Rectification: non-synchronous rectification Module Properties: non-isolated constant current and voltage module. Advantage: CC CV Low ripple When the module charges a battery, it first use constant current to protect the battery. check the curse above. Module highlights: 5A high power ,high efficiency and low ripple with power indicator !!! 1. Input voltage range:4~38VDC(Note:input voltage not exceeding 38V) 2.

Features: 1. LED power indicator. 2. Button to switch measurement of the input or output voltage, and LED indicates the current measurement of the input or output voltage; The nixie tube can be turned off by another button. Mentioned states are able to be memorized, is not lost even if the power is disconnected. (On-board marked "IN" LED is turned on, the nixie tube display input voltage value, "OUT" LED bright display is the output voltage value). 3. Special launch, the voltmeter calibration function, will never exist voltmeter inaccurate! Voltmeter calibration method: (1) Output voltage calibration steps Step 1, adjust the right button so that "OUT" LED lighted, the voltmeter shows the value of output voltage; Press the right button for more than 2 seconds, release, voltmeter and "OUT" LED flashes in synchronization so that you enter the output voltage calibration mode. Step 2, press the right button (normal speed), the voltage value is adding up a unit; Press the left button, minus a unit; Due to a unit is less than 0.1V, the minimum voltage display to 0.1V, so you need to continuously press 1-5 times to see the voltmeter change 0.1V, how many times voltmeter change 0.1V by pressing the key, depending on the current display voltage, the higher the voltage, the fewer the number of press. Step 3, press the right button for more than 2 seconds, release, to exit the output voltage calibration mode. All parameters set to automatically power down to save. (2) Input voltage calibration steps Step 1, adjust the right button so that "IN" LED lighted, the voltmeter shows the value of input voltage; press the right button for more than 2 seconds, rele
