Feature
●Using internal oscillation frequency of 400 kHz, it belongs to the second generation of switch voltage regulator, low consumption and high efficiency. Widely used in storage batteries, power transformers, DIY adjustable stabilized power supply, industrial equipment, 9-12V, 12V-18V, 18V-24V, etc
●The voltage meter error is ±0.1V and the measurement range is 5V to 35V
●The touch button switch changes the measurement of the input or output voltage and features an indicator light to indicate the measured voltage
●Maximum output current is 4A max. The working current is about 2A, and if more than 2A, we recommend adding a heat sink
●The input and output have screw terminals that can be easily connected without soldering iron and hold the solder pad for solder connections
Description
Specifications: Input Voltage: 4.5V-32V Output Voltage: 5V-35V (Adjustable) Max.Output current: 4A Switch frequency: 400 kHz Operating temperature: -40 °C to + 85 °C Size: 66 * 36 * 14 mm/2.59 * 1.41 * 0.55 " Description: 1. The default display when you turn on the first time, the input indicator in will light up.Press the button and the output voltage will be displayed, and the output indicator OUT. The last setting is saved even when the power is turned off and the system is restarted. 2. I/O Voltage Measurement Error Calibration: Hold the button and turn the switch on at least 4 seconds and release and input voltage. Measurement error calibration function, indicator IN light (input voltage calibration), and display flashes to display calibration value (default is 0.0).Press the button to change this value (from -0.5V) 0.5V) after adjusting the input voltage calibration value, press and hold the button for more than 2 seconds and then release the output. Voltage error calibration function, indicator OUT light (output voltage calibration) and calibration value are displayed.Adjustment Method: Same as input adjustment.After adjustment, long press button for more than 2 seconds and release to save the setting Normal voltage display.Calibration values are instantly activated and stored in case of a power outage. 3. Turn off the voltmeterPress and hold the switch for more than 1 second. Please release within 4 seconds before turning off the voltmeter.Turn off the voltmeter and press the switch to turn it on.Package: 1 x Boost Converter Module
