Power supply voltage regulator module, adjustable stabilized converter board 0-30V to 1.25V-28V

Features: 1. [HEAT DISSIPATION] The LM317 adjustable regulated power supply board has heat sinks; its special shape provides good heat dissipation. 2. [POTENTIOMETER] Equipped with a duplex adjustment potentiometer, convenient for voltage adjustment. 3. [VOLTAGE RANGE] The input voltage range is 0 to 30V DC or 0 to 30V AC, and the output voltage is 1.25V to 28V, continuously adjustable. 4. [DIGITAL DISPLAY] Added digital display voltage function, easy to check, very suitable for voltage testing. 5. [MULTIPLE USES] The voltage reducing board is compact, easy to install, and can be used for various electrical equipment. Specifications: Item Type: Voltage Regulator Module Product Model: LM317 Input Voltage Range: DC 0-30V, AC 0-30V Load: 2A or less Output Voltage: 1.25V-28V continuously adjustable PCB Size: Approx. 68 x 51 mm / 2.7 x 2 inches Package List: 1 x Voltage Regulator Module Note: This power supply is a buck module. If the input voltage is higher than the output voltage, the voltmeter will display an abnormal reading. If the voltmeter reading is below 4.5V, and the output voltage is normal, this is not a voltmeter quality issue.
