High Quality Features: Ultra-wide input voltage range of 4.5-32V (typically under 5V, the digital tube won't work), with an optimal operating voltage range of 5-32V. Ultra-wide boost output voltage range of 5-55V to meet your needs. Built-in 4A high-efficiency MOSFET switching tube for efficiency up to 94%. Ultra-high switching frequency of 400 kHz achieves excellent results with a small capacity filter capacitor, reducing ripple and volume. Features a power indicator for easy monitoring of working conditions. Adopts an advanced voltage microprocessor, ensuring a voltmeter error of only 0.05V within a range of 0-35V. The voltmeter can display data and self-calibrate. (Note: To ensure voltmeter accuracy, ensure the input voltage is above 4.5V). Press the button to switch between measuring input or output voltage. An indicator light shows which voltage is being measured and saves settings, even after power off and on. The voltmeter can be turned off and easily tapped when the display is not needed. Equipped with terminal blocks for easy wiring without soldering, and a wire binding point is retained. Features overheat protection and short circuit protection for safe operation. Specification: Model: XL6009 Material: Fiberglass board, electronic component Size: app.60 x 37mm/2.36 x 1.46in Color: Blue Quantity: 1 Pc Product Parameters Module Function: Non-isolation boost Rectifier System: Non-synchronous rectifier Input Current: 4A (max.), no-load 18mA (5V input, 8V output, no-load less than 18mA.
