상품 특징

• Intuitive Display: Equipped with a power indicator light and a high-precision voltmeter (error ±0.05V, measuring range 0 - 40V, accuracy guaranteed when the input voltage ≥ 4V). Lightly press the right button to switch between measuring input and output voltages. The switching status is indicated by a light, and the settings are retained even after a power outage. The left button can be used to turn off the voltmeter.​
• Convenient Wiring: Fitted with terminal blocks, enabling easy use without the need for a soldering iron. Soldering connection points for wires are also retained.​
• Wide - Range Voltage Regulation: Input voltage ranges from 4.0V to 40V (must be at least 1.5V higher than the output voltage). Output voltage is continuously adjustable from 1.25V to 37V (input voltage needs to be 1.5V higher than the output voltage).​
• Efficient Output: The maximum output current reaches 3A, with a normal stable operating current of 2A. It adopts a second - generation switching voltage regulator with an internal oscillation frequency of 150KHz, featuring low power consumption and high efficiency.​
• Safety Protection: Equipped with overheat protection and short - circuit protection functions. A heat sink is required when the power exceeds 15W. If the output voltage cannot be adjusted, rotate the potentiometer counterclockwise for more than 10 turns to restore normal operation.
