Module performance and features: ● With Power Indicator ● With a voltmeter display and the voltmeter can be selfobrated.using a more advanced voltage microprocessor, Voltmeter Error 0.05V, Range 0 ~ 40V. (Note: to ensure the Accuracy of the Voltmeter, please make the input voltage is greater than 4.5v) ● Touch the Button to Switch Input Output Voltage Measurement, and The Input H Circuit Voltage is Being Measured, and Save the Setting, Even if the Power is turned on again. 't easily use the SOLDERING Iron and Keep the Wire Connection Point. ly adjustable. (The Input Voltage must be 1.5V Higher than the Output Voltage) ● Output current up to 5a, it is a refoCommended to use with 4.5a ● Output power up to 75w, more than 50w.strengthen Add a small radiator) ● High Conversion Efficiency, Up to 96% (Efficiency and Input, Output Voltage, Current, Pressure Related) ● Operating Frequency: 180KHZ ● LOADLATION Rate S (i) & le; 0.8%, Voltage Regulation Rate S (U) & Le; 0.8%● With Overheat Protection and Short Circuit Protection (but the Short Circuit in Case of Accident, Try Not To Short Circuit) Meter is Generally not Fine-Tuning, but most of the Error Or in Requirements, If You Are Not Suer to Take the Voltmeter, You Are Suer to Do It F skin, IT, IT, IT MISTAKEE. is not the reals of the product, but the fork! When you determine Not Think that following content is to adjust the output voltage) 1. The Output Voltage, Long Press The Right Button for 2 Seconds After the Release, the Voltmeter and the Output Voltage Indicator "Out" Synchronized Flashing, Then Enter the Voltage Adjstentent Mode Similarly, In the Input Voltage Voltmeter Display , Long press the right button for 2 seconds after the release, the voltmeter and input voltage indicator "in" Sync Flashing, then Enter the Input Voltage Adjustment mode. entrance; 2. Touch the Right Button, Press the Voltage One Unit, Touch the Left Button, The Voltage Will Drop One Unit; BeCause a Unit Voltage is Less Than 0.1V, So Need to Press 1-5 Times to See the Voltmeter Switch the 0.1V. , The special number of consecutive keys depends on the current Display Voltage, The Display Voltage Current is high, the number of keystrokes will be smaller; 3. After adjusting the voltage, press the right button for 2 seconds to release, then you can Exit the Voltage Calibration Mode, All Parameters Set to Automatically Save POWER.Note: This Adjustment Voltage Range Can Be Accurate Voltage Value, this function is to keep your highway reviews and designs, please Rest assured to use. Ill be subject to change with notice.
