a¦aЂ“a°a?a»a?a§a 1/2 aЂ~a©a?aµ 6 5A CC/CV Adjustable Power Step-down Charge Module LED Driver With Red Voltmeter Q Description: 100% brand new and high quality Features: LED power indicator. 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. With voltage meter display and voltage meter can be self calibration. The voltage of the more advanced microprocessor, voltage meter error of ± 0.05V, range 0~40V. (Note: to ensure the voltage meter accuracy, please ensure that the input voltage is more than 4.5V) 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). Voltmeter can be turned off when not needed Tap the left button can be easily achieved . Touch the button to switch the input or output voltage measurements and has a light display which is being measured voltages , and save the settings , even power off and then on. 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, release, voltmeter and "IN" LED flashes in synchronization so that you enter the input voltage calibration mode. -Steps 2 and 3, consistent with the output voltage calibration method. Performance parameters: Input voltage range:4~38VDC(Note:input voltage not exceeding 38V)(input voltage to output voltage higher than 1.5V above) Output voltage range:1.25-36VDC adjustable (input voltage should be 1.5V higher than the output voltage) Output current: 0-5A,Recommended for use in the 4.5A Output power: 75W voltmeter range: 4 to 40V, error ±0.1V Operating frequency: 180KHz High efficiency up to 96%(efficiency is related to the input, the output voltage, current, pressure difference) Load regulation S (I)
