Product Description

Step-Down DC 5-30V TO 1-26V DC-DC Constant voltage constant current buck DC-DC module, battery charging module, LED driver

Specifications

 Description: Input voltage 5-30V output voltage 1-26V adjustable

      Constant current point (0.4A 0.8A 1.2A 1.6A) ± 5% free to choose no special requirements issued version 1.6A requirements, please note you modify!
      Remained stable voltage output of the power supply is operating in constant voltage mode when the load current is less than 1.6A
      When the load current increases to 1.6A module will automatically limit the load current, no further increase
      Output current to maintain the stability of the power in the constant current mode
      Application examples
      1, lithium rechargeable
         Adjust the potentiometer so that the output voltage is equal to 4.2V access lithium battery (the output cathode connected battery positive) power will give the lithium 1.6A constant current charging, when the lithium battery voltage rises to 4.2V module will lithium constant voltage charging until the battery is fully charged!
      2, used in parallel to the lead battery segment constant current constant voltage charging
     Example: two modules in parallel to the battery charging 12v lead
        2 module voltage were adjusted to 13.5V 13V battery directly parallel access
        In the early stages of charging batteries until the voltage rises to 13V charging current decreases to 1.6A 1.6A constant current charging when the battery voltage is greater than 13V battery will be, until the charge to 13.5V 3.2A constant current charging
       Charge the battery into constant voltage mode until the battery is fully!
