TÉRMINOS Y CONDICIONES

------------------------------------------

- El producto se trae a pedido, en un transcurso de 15 a 25 dias, si alguna restriccion de un ente gubernamental o de salud publica cambia o restringe vuelos, los pedidos pueden demorar mas tiempo.
- Precios pueden cambiar previo aviso. Depende de precio con proveedores o existencia.
- Fotos referenciales del producto, consulte no mas
- Despachamos a todo Chile con Starken.
- Productos importados de Estados Unidos, es probable que los productos electronicos trabajen en 110V y NO en 220V, podria usar un transformador, para mas informacion primero nos puedes preguntar todas las inquietudes que tengas.

-Input Voltage:DC 4V to 40V (input voltage must be 1.5V higher than the output voltage, no boost).
-Output Voltage:DC 1.5V to 35V voltage is continuously adjustable.
-Output current:2A (normal and stable) and 3A max.
-Updated Version: with reverse voltage protection, over-temperature and short-circuit protection, thus making it much safer to use.
-Easy to use: Connect to power source, using a mini screwdriver to increase or decrease output voltage by adjusting the screw on the blue potentiometer and monitor voltage with multimeter to get the needed voltage, clockwise to step up voltage and counterclockwise to step down voltage. (Factory default stays a high voltage, you need to contrarotate about 7-15 circles before the voltage starts ramping down, 1 circle means +/- 1V)

Specifications:Model: LM2596 / Digital Tube VoltmeterInput voltage: DC 4V - 40VOutput Voltage: DC 1.5V - 35V (adjustable)Output Current: 3A (max.)Conversion Efficiency: 92% (max.)Switching Frequency : 150KHzOperating Temperature: -45? to +85?Size(L x W x H): 62*35*14mmFunction:Built in over-temperature protection functionBuilt in current limit functionBuilt in output short-circuit protection functionHow to use:1. Press the button in a short time (1 second) so that "in" LED lighted, the voltmeter shows the value of input voltage.2. Press the button in a short time (1 second) again so that "out" LED lighted, the voltmeter shows the value of output voltage.3. Rotate the top screw of potentiometer clockwise to boost the value of the output voltage, anti-clockwise to reduce it.4. Long press the button between 1 and 4 seconds to turn off the voltmeter.How to adjust accuracy of input/output voltage:(for the person who need a highly accurate value of number)1. Long press the button for more than 4 seconds, then release, voltmeter and "in" LED flash in synchronization entering into the input voltage calibration mode.2. Press the button in a short time (1 second) to adjust the value (range from -0.5 - 0.5V), positive means to rises units, negative means to minus units. (Due to a unit is less than 0.1V, so you have to continuously press 1 to 5 times to see the voltmeter change 0.1V).3. Long press the button for more than 2 seconds and then release to enter the output voltage calibration mode.4. After calibration, long press the button for more than 2 seconds all parameters will be saved automatically and back to the voltage display.Package include:2 x LM2596s buck converter DC to DC
