1、Suitable for power boost modules that can be used when there is no suitable high‑voltage power supply to match 2、With the voltage display function, can display the input voltage, can also display the output voltage, just click the button to switch 3、The voltage accuracy of the test is quite high and the output voltage (5V-45V) can be adjusted manually for practical use. 4、Adopted of high quality electronic components, and accuracy process, ensure for the durability 5、The product has high accuracy, voltage control accuracy of up to 0.1V, small size and easy to install and replace Item Type: Boost Module Material: PCB Use: This product is used in the power boost module when there is no suitable high-voltage power supply to match the drive load. Input Voltage: 4-35V Output Voltage: 5-45V Input Current: Maximum 5A Maximum Power: 100W Pressure Control Accuracy: 0.1V Product Size: Approx. 72 x 48 x 18mm / 2.8 x 1.9 x 0.7in How to Use: 1, The XH-M411 input connected to the power supply, the applicable supply voltage is 4-35V, pay attention to its positive and negative pole. 2. Turn on the power switch and the XH-M411 screen will show the output voltage after the current boost. 3. If the output voltage is not enough to meet the operating voltage of the load, the voltage can be adjusted by the power thinker. 4. Hit the output load, pay attention to the positive and negative poles between them. 5. Press the voltage switch key can switch the display output voltage and input voltage 1 x Boost Module
