Description

Moduł przetwornicy DC-DC step-down obniżającej napięcie, wykonanej na układzie LM2596, przetwornica posiada woltomierz umożliwiający pomiar napięcia wejściowego oraz wyjściowego - zmiany dokonujemy wciskając przycisk na płytce przetwornicy, o tym które napięcie jest mierzone informują nas diody LED.


Dane podstawowe:

  • napiecie wejsciowe: 4,5-40V, musi być conajmniej o 1V większe od napięcia wyjściowego
  • napięcie wyjściowe: 1,5-3,7V
  • prąd maksymalny 3A, może być wymagany radiator
  • dokładność woltomierza 0.1V
  • wymiary: 36x66mm


Introductions 

  • With a voltage meter display, voltage meter error�0.1V, Range 0~40V. (Note: The input voltage is below 4V, on-board voltage meter does not work does not display).
  • Original touch of a button to switch the input or output voltage measurement, and a light show which way you are measuring the voltage and keep the last setting, even the power off and then boot.
  • Voltmeter can be turned off, press the switch a second or more and less than four seconds, let go can be closed
  • Input and output voltage measurement error than the standard functions, long press switch for 4 seconds or more, let go after entering the voltage measurement error than the standard features, this time in light (calibration input), the digital display flashes than positive (factory parameters is 0.0) , then short press the button to change the value (values range from -0.5 to 0.5, the unit is V), a positive number indicates an upward calibration, negative downward calibration. Adjust the input than the standard value, long press the button more than 2 seconds, let go into the output error correction, this time out lights (calibrated output), and display the output calibration value adjustment methods and inputs the same, the whole good output than the standard value, long press the button more than 2 seconds, let go and save the set values and return to the normal display voltage correction value setting takes effect immediately and is non-volatile.
  • With terminals, no soldering iron can also be easy to use, and retention wire connection point
  • Input Voltage 4.0~40V (input voltage must be greater than the output voltage to a high 1v or more.)
  • Adjustable output voltage range of 1.25V~37V continuously adjustable (must be greater than the input voltage to output voltage higher than 1V)
  • The maximum output current of up to 3A, normal and stable operating current of 2A
  • Using an internal oscillator frequency 150KHz, belongs to the second generation of switching voltage regulator, low power consumption, high efficiency
