Descripción (En Ingles):

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: 7-35V,
  • Output voltage: 1.25-30V adjustable
  • Output Current: 3A (more than 15W, install 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 ℃ to +85 ℃) (ambient temperature exceeds 40 ℃, lower power use, or to enhance heat dissipation)
  • Full load temperature rise: 45 ℃
  • 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 ℃ to 100 ℃, 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.)
