New NC version, integrated voltage and current regulation function, makes voltage and current regulation more convenient, accurate and stable.
The module is adjustable step-down module which can change the output voltage by regulating the blue adjustable resistance of the module. The voltage difference between input and output voltage is 1V and the minimum output voltage is 0.8V.
Dual LED display, the LED end with “V’ and “A”. Straightforward to distinguish between current and voltage display. This module adopts high quality LED digital tube, super bright, can be clearly displayed even under the sun.
The module uses SCM take sample and display voltage, and carries out a large amount of data processing, which makes LED display more precise and stable.
To guarantee the high performance and quality of product, we adopts high quality chip, high efficiency, low heat and the maximum efficiency is up to 95%, the maximum current can reach 5A. Meanwhile, with the original TI Op Amp to control the output current, makes the overall output more stable.
This module adopts low ESR original SANYO filter capacitor which can make the ripple voltage as low as 50mV. In the meanwhile of keeping the high performance and reliability of the module, use full surface mounting technology and reflow soldering to realize the module the ultra small volume.
Charge for lithium ion battery: when the voltage of lithium ion battery is low, charge it by constant voltage directly will lead to large differential pressure and excessive current during charging, which will cause damage on the battery. Therefore, at the beginning of charging for the battery, we should use constant current and then automatically switch to constant voltage when charging to a certain extent.
