DROK® DC-DC 80W Auto Boost Buck Voltage Regulator Stabilizer 5A 3.3V-30V to 0.5V-33V LED Display Volt Stabilizer Transformer Adjustable Output;

Parameters:
Input voltage: DC 3.3-30V
Output voltage: DC 0.5-33V
The maximum output current: 5A
The maximum output power: 80W
Conversion efficiency: 91% (the data comes from the condition of 12V input, 19V output, 2A)
Dimension: 78 * 48 * 22mm

Push-button function:
1. Quickly pressing the button less than 0.5 second can toggle display the input and output voltage. When the indicator light shows red, it refers to input voltage; when the indicator light shows green, it refers to output voltage.
2. Pressing the button about 1-2 seconds will turn off the display, then pressing again will turn on the display.
3. Pressing the button more than 2 seconds will enter into voltage reference setting, at this time it displays 3.33V by default and red light is flashing, which implies calibration of input voltage reference, then quickly short press the button to change the value whose range is from 3.28-3.38V. After setting to an appropriate value, long pressing the button over 1 second will enter into output voltage reference setting, and the green light is flashing, then short press to change the value. After setting to an appropriate value, long pressing the button over 1 second will save the value and return to the normal display.(Tips: when the displayed voltage is lower than actual voltage, turn up the reference voltage; when the displayed voltage is higher than actual voltage, turn down the reference voltage.)

Package includes:
1 x Buck Boost Voltage Regulator
