100% brand new and high quality Features: Ultra-wide input voltage 4.5-32V (Normally operating below 5V, but the digital tube does not work), the optimal working voltage range is 5-32V. Ultra wide boost output voltage 5-55V to meet your needs. Built-in 4A high efficiency MOSFET switching tube for up to 94% efficiency. The ultra-high switching frequency is 400KHz, which can achieve very good results with a small-capacity filter capacitor with smaller ripple and volume. With power indicator, easy to know the working conditions. Adopting more advanced voltage microprocessor, the voltmeter error is 0.05V, and the range is 0-35V. And the voltmeter can display the data and self-calibrating.(Note: To ensure the accuracy of the voltmeter, please ensure that the input voltage is above 4.5V) Touch the button to switch the measurement or input or output voltage. An indicator light shows which voltage is being measured, and save the settings, even if it is powered off and then on. The voltmeter can be turned off and easily tapped when the display is not needed. With terminal block, no soldering iron can be used easily, and the wire bond point is retained. It has overheat protection and short circuit protection, safe to use.
