Description

Non-isolated step-down constant current, constant voltage module (CC CV) charging module with charge complete indicator. The voltage output is adjusted by turning the volt adj potentiometer, measured by a voltmeter at out+ and out- The finished charging LED voltage threshold is adjusted by turning the finished charging LED adj potentiometer, measured by a voltmeter at out+ and out-. The maximum current is adjusted by turning the const current potentiometer, measured by connecting a current measuring voltmeter between out+ and out-. Connect the device, eg. Battery or LED. The module will regulate the output voltage, if the current drawn by the device is greater than the value set, the current will be regulated instead of the voltage, constant current LED will light. When the output voltage is greater than the value set by the finished charging LED adj potentiometer, the finished charging LED will light.

Features

  • Input voltage: 5-35V
  • Output voltage: 1.25-30V adjustable
  • Output Current: Rate 3A, Max 4A ( If more than 15W, please install the heat sink, this item do not include heat sink)
  • Constant current range :0-4A (adjustable)
  • Revolving light current: constant current value * (1% -100%), Revolving light current value Linkage with the constant current value, such as the constant current value is 3A, Revolving light current is set to constant current of 0.1 times (0.1 * 3A = 0.3A) when adjusted to the constant current value when the 2A, then Revolving light current is 0.2A (0.1 * 2A = 0.2A). Default 0.1 times
  • Minimum voltage pressure: 2V
  • Output power: natural cooling 15W, (if install heat sink can be 25W)
  • Conversion efficiency: 92% (the higher the output voltage, the higher the efficiency)
  • Output ripple: 20M bandwidth (for reference)
  • Input 12V Output 5V 3A 60mV (MAX)
  • Operating Temperature: Industrial (-40°c to +85°c) (if ambient temperature exceeds 40 °c, please lower power use, or to enhance heat dissipation)
  • Full load temperature rise: 45°c
  • No-load current: Typical 10mA (12V to 4.2V)
  • Load regulation: ± 1%
  • Voltage regulation: ± 0.5%
  • Dynamic response speed: 5% 200uS
  • Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease)
  • With reverse input protection diode
