ITEM NAME:Dual Display 5V-30V To 0.8V-29V Step Down 15A Constant Current Constant Vol V6D6 Dual Display 5V-30V To 0.8V-29V Step Down 15A Constant Current Constant Vol V6D6 Module, properties: reducing module not isolated Rectifier mode: non-synchronous rectifier Conversion efficiency: 95% (highest) Output wave: 50mV (maximum) 20m bandwidth Input impedance: 50 milliohms Features: 1. This module uses high quality LED digital tube manufacturing, high brightness, even in the sun can show clearly. 2. This module uses the original imported Micro-Micro-controller and the display voltage, and software in a large amount of data processing, so that the screen is accurate and stable. 3. The module for all chip technology, technological skills, while the ultra small size. Application: 1. Lithium-ion battery charge: when the voltage of the lithium-ion battery is relatively low, if the direct use of constant voltage load, due to the pressure difference, resulting in the charging current is Too much large, which leads to battery damage, so the battery starts to use constant current load, when the load to some extent automatically changes to the constant voltage load 2. This module is adjustable buck module, you can adjust the module above the blue adjustable resistor to change the output voltage. The differential pressure of input and output is 1 V, the minimum output voltage of 0.8 v. 3. in- (negative input), in + (positive input), output- (negative output), and out + (positive output) the module must be connected correctly, otherwise the module may be damaged colour:Picture color Material:PC+ metal size:5.1*2.63*1.4cm Package Contents: 1 x Dual Display Module.Input impedance: 50 milliohms. Output wave: 50mV (maximum) 20m bandwidth. 1 x Dual Display Module. colour:Picture color.
