Power Supply Voltage Regulator Module Adjustable Stabilized Converter Board 0‑30V to 1.25V‑28V

Feature: 1. [HEAT DISSIPATION] The LM317 adjustable regulated power supply board has heatsinks, the special shape has good heat dissipation effect. 2. [POTENTIOMETER] Equipped with duplex adjusting potentiometer, which is convenient to adjust the voltage. 3. [VOLTAGE RANGE] The voltage input range is DC 0‑30V or AC 0‑30V, and the output voltage is 1.25V‑28V continuously adjustable. 4. [DIGITAL DISPLAY] Added the digital display voltage function, easy to check, very suitable for voltage experiment. 5. [MULTIPLE USAGES] The voltage reducer board is compact, easy to install, and can be used for various power equipment. Specification: Item Type: Voltage Regulator Module Product Model: LM317 Voltage Input Range: DC 0-30V, AC 0-30V Load: 2A or less Output Voltage: 1.25V-28V continuously adjustable Circuit Board Size: Approx. 68 x 51mm / 2.7 x 2in Package List: 1 x Voltage Regulator Module Note: This power supply is a buck module. If the input is greater than the output, the voltmeter will display abnormally if the voltmeter is lower than 4.5V, and the output voltage is normal, not the voltmeter quality issues.
