yal DC-DC 12A Step-down Constant Voltage Constant Current Module Solar Lithium Charging LED

Giới thiệu yal DC-DC 12A Step-down Constant Voltage Constant Current Module Solar Lithium Charging LED

Description:
100% brand new,high quality
Pay attention:
1. Please use this product, the module input and output are not together, this will cause the module's current sampling resistor is bypassed, so that the module can not adjust the output current size, then the case of large load easily Burn the module.
2. A customer reflects the module output voltage can not be adjusted, when you encounter this problem, please counterclockwise rotation of the CV potentiometer more than 20 laps, and then use the module can be normal adjustment of the voltage. Because the module factory, The default output voltage of about 18V. We are not responsible for the return of such questions and freight, thank you for your understanding.
3.12A synchronous rectifier buck module only, other accessories demo in the picture is not included.

Three ways to use the module:
a. as a general step-down module with overcurrent protection capability;
b. As a variety of voltage lithium batteries, batteries, nickel-cadmium nickel-metal hydride batteries (battery pack) charger used for solar panels, wind turbines and other occasions;
c. used as a high power LED constant current drive module;

Module parameters:
ModUle Name: 12A synchronous rectifier buck module, constant voltage constant current
Module nature: non-isolated step-down module (BUCK) synchronous rectification
Input voltage: 4-32V (limit 35V) Please keep the voltage margin.
Output voltage: 1.2-32V continuously adjustable (default output of about 18V, if the power to the module and found that the left and right rotary voltage potentiometer output voltage has not changed, you first turn the voltage potentiometer counterclockwise rotation of more than 15 laps )
Input and output minimum pressure difference: 0.8V
Output current: 0-12A long time natural heat within 8A, the temperature does not exceed 60 degrees. Please reduce power when the ambient temperature is high.
Conversion efficiency: up to 98% (efficiency and input, output voltage, current, pressure related)
Short circuit protection: Yes (limit current is current constant current value)
Input Reverse Protection: None (if required, enter the string in the input diode)
Output anti-backlash protection: none (if necessary, in the output string into the diode, for charging applications, please add the anti-diode between the output of the module and the battery, otherwise it will damage the module.)
Material: Fiberglass sheet + electronic components + stainless steel
Size: approx.70mmx40mmx30mm/2.76x1.57x1.18
Quantity: 1 Pc
Note: constant current set when the voltage is higher than 1.2V, otherwise the constant current function will be invalid.

Package include:
1 x 12A Voltage Constant Module
