【Internal Configuration】– Using duplex adjustment potentiometer. Military grade double-sided circuit board.Adopt high-frequency power supplement dedicated capacitor, more stable performance. 【Main Function】– 317 Voltage Regulator can be connected to the load within 2A, AC or DC input voltage, the output voltage is DC 1.25V-28V continuously adjustable. 【Digital Tubes】– Add digital tubes to display output voltage, the output voltage is clear at a glance. 【Warm Tips】– Due to the working voltage of digital tubes is 4.5V, our variable voltage regulator displays normally only when the voltage is higher than 4.5V.When inputting 5V, it can output 1.25-2V and won’t output a higher voltage. 【Heat Dissipation】– With a heat sink, the voltage booster can dissipate heat quickly when the product works to cause temperature rise, and the heat dissipation effect is good.
