It is a DC Buck Converter/Power Adapter/Power Supply Module, Input voltage:DC 7~35V, Output voltage: DC 1.25~30V adjustable, Output Current: 3A, Application: Power adapter, industrial equipments, electronic equipment, Communications Equipment, Power Tools, Car Driving Recorder, Car GPS, Car audio, LCD TV, Advertising screen, Monitoring System, LED lights, Fan, intercom and monitor system, etc.

Module parameters:
  • Properties: non-isolated step-down constant current, constant voltage module (CC CV) charging module
  • Scope: High-power constant current LED driver, battery charger (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-metal hydride batteries (battery) charger, solar panels, wind turbines
  • Input voltage: DC 7~35V,
  • Output voltage: DC 1.25~30V adjustable.
  • Output Current: 3A (more than 15W, please install heat sink, this item do not include HEAT SINK)
  • Constant current range :0~3A (adjustable)
  • revolving light current: constant current value * (0.1),
  • 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 constant current value to 2A, then revolving light current is constant current of 0.1 times (0.1 * 2A = 0.2A). this version is 0.1 times fixed
Feature:
  • Dropout voltage: 2V
  • Output power: natural cooling 15W, 25W with heat sink
  • Conversion efficiency: 90% (up to 90% (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) (ambient temperature exceeds 40 °c, lower power use, or to enhance heat dissipation)
  • Full load temperature rise: 45 °c
  • No-load current: Typical 10mA (12V switch 4.2V)
  • Load regulation: ± 1%
  • Voltage regulation: ± 0.5%
  • Constant accuracy and temperature: the actual test, the module temperature changes from 20 °c to 100 °c, less than 1% change constant current value (constant current value 1A)
  • Dynamic response speed: 5% 200uS
  • Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease),
  • potentiometer close to the input is Voltage regulation (CV),
  • potentiometer close to the output is current regulate (CC),
  • Indicator: two-color LED charging indicator light red, fully charged light green (do not connect load light green)
  • Output short circuit protection: Yes, constant current (constant current setting values)
  • Input reverse polarity protection: Yes,
  • Output to prevent reflux: Yes, the output has an internal series a diode to prevent reflux.
  • Connection: Welding, plus pin can be directly soldered to a PCB
Battery Charging method:
  • 1. Make sure the recharge battery float voltage and charge current, input voltage of the module.
  • 2. adjust constant voltage regulator, the output voltage about 5V.
  • 3. With a multimeter ( to 10A) Measuring output Short-circuit current, Also adjust the constant regulator allows Output current reaches a predetermined charge current value;
  • 4. Adjust Constant regulator allows Output voltage reaches the float voltage;
  • 5. connected to the battery, try charging.
  • (1,2,3,4 step input connect power, output do not connect battery.)
LED constant current driver Usage:
  • 1. Make sure LED current and the maximum operating voltage;
  • 2. adjust constant voltage regulator, the output voltage about 5V.
  • 3. With a multimeter ( to 10A) Measuring output Short-circuit current, Also adjust the constant regulator allows Output current reaches a predetermined LED working current value;
  • 4. Adjust Constant regulator allows Output voltage Reach LED maximum working voltage;
  • 5. Connected to the LED, test.
  • (1,2,3,4 take steps input connect power, output do not connected LED.)
