【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.
