Free shipping DC-DC automatic pressure regulator Power module adjustable DC power car 5V12V24V
Model Number: DC-DC automatic pressure regulator
Brand Name: BETTERSHENGSUN
High efficiency of automatic voltage regulator, with voltage display, input support to 3.3~30V, output 0.5V~33V can be adjusted. Advanced aluminum shell, the maximum efficiency of up to 91% efficiency, with over - thermal protection, and display tips. Wide range of application of the boost with the buck seamless automatic switching, the input voltage can be higher than the output voltage can be lower, that is, the input voltage changes, the output voltage remains constant, such as the use of the car, you can put the voltage regulator to 12V.
Input voltage: 3.3~30V DC not positive or negative, or damage
Output voltage: 0.5~33V DC
Maximum output current: 5A
Maximum output power: 80W long time continuous operation, please strengthen heat dissipation, better leave a certain margin
Conversion efficiency: 91% (12V input, 19V output 2A time measured)
Module size: 78*48*22mm (length and width)
Note: This module is a voltage regulator module, not with constant current function, can not output directly to the battery (that is, the output can not directly connect the battery, such as with the battery itself with charging circuit can be connected, such as charging treasure).
Key function details:
1, quickly press and let go (press the duration is less than 0.5 seconds), to toggle the display of input and output voltage, when the indicator light is red when the display is the input voltage, when the indicator light is green when the display is output voltage.
2, press this button for about 1 seconds ~2 seconds, let go after the turn off the display, and then press the button to open the display again.
3, press this button lasted for more than 2 seconds, let go into the voltage set up to display the voltage reference, then the default display 3.33 and flashing red lights, representative is more accurate is the reference input, quick, short press the button to change the numerical values 3.28~3.38. Transferred to the appropriate value length according to the button more than 1 second, let go into the output voltage reference set, this time lights, short press the button to change the values, transferred to the appropriate value after long button more than 1 second, save setting of the voltage reference and return normal display. (hint: when the voltage is lower than the actual voltage Shidiao high reference voltage, when the voltage is higher than the actual voltage tune small reference voltage)
Reminder: power module work is sure to heat, this module natural cooling power in the 60W or so, such as the long time stable working 80W, you need to do the appropriate to strengthen the heat, otherwise it will overheat protection. In the case of a large current, there may be a sound, which is a normal phenomenon.
