Input impedance: 50 milliohmsInstructions:Module above indicated IN-(input negative), IN+(positive input), OUT-(negative output), OUT+(positive output) must be connected to the right, otherwise may cause damage to the module.
Battery charging method:
(1) determine the battery\'s float voltage and charging current, input voltage module
(2) adjustable the constant potentiometer, let the output voltage regulation to about 5V.
(3) multimeter 10A current block measurement output short circuit current, and adjusting the constant current charging current potentiometer output current reaches a predetermined value;
(4) charging turn lamp current default delivery is 0.1 times of charging current (current value).
(5) adjustable constant potentiometer to the output voltage to the floating charge voltage;
(6) battery charging, test.
(1, 2, 3, 4, 5 steps for the module input power, output no-load not connected with the battery.)
LED constant current driving method:
To determine the current you need to drive LED and maximum working voltage;
Adjustable constant potentiometer, the output voltage is regulated to 5V.
Using a multimeter 10A current block measurement output short circuit current, while regulating constant current potentiometer output current up to LED working current of a predetermined;
Regulating constant potentiometer to the output voltage to the LED maximum working voltage;
Connected to the LED, the test machine.
(1, 2, 3, 4 steps for the module input power, output no-load not connected with the LED lamps.)
Comunication Protocol Instruction:
This module can communicate with computer,so that the current and voltage reading can be displayed by the computer.
Because the output of this module is a TTL level,in order to communicate with computer, thid=s level signal has to be transfered to a RS232 level which can recognize by the computer, this module( item number:281409886899)is used to do this job
Application examples:Rechargeable lithium-ion battery:
When the lithium-ion battery voltage is relatively low, if the direct use of constant voltage charging, the voltage difference due to the larger, leading the charge current is too large, resulting in damage to the battery, so when you want to start using the constant battery current charging, when the charge to a certain extent automatically switches back when the constant voltage charging.
Package Included:1PCS * 5A Adjustable CC/CV Display Step Down charge Module LED Panel Voltmeter Ammeter
