Module parameters:

  • Module Properties: non-isolated step-down constant current , constant voltage module (CC CV) charging module
  • Input voltage : 7-40V
  • Output voltage :1.2-35V continuously adjustable
  • Output Current: 8A ( when power tube's temperature exceeds 65 degrees, please add cooling fan )
  • Constant current range :0.2-12A ( adjustable )
  • Turn lamp current : constant current value * ( 0.1 ) , turn the lamp current and constant value linkage, such as constant current value is 3A, turn the lamp current is set to a constant current is 0.1 times (0.1 * 3A = 0.3A).
  • Lowest pressure : 1V
  • Output Power: Maximum power is about 300W
  • Conversion efficiency : up to about 95%
  • Operating frequency : 300KHZ
  • Output ripple : 20M bandwidth
  • Input 24V Output 12V 5A ripple around 50mV ( excluding noise )
  • Operating temperature : Industrial grade (-40 ℃ to +85 ℃) ( please note the actual use of the power tube temperature , high temperature heat strengthened please )
  • No-load current : Typical 20mA (24V switch 12V)
  • Load regulation : ± 1% ( constant )
  • Voltage regulation : ± 1%
  • Dynamic response speed : 5% 200uS
  • Potentiometer adjustment direction : clockwise ( increase ) , counterclockwise ( decrease ) . the potentiometer(CV) closed to the input voltage is used to regulate voltage,  the potentiometer(CC) closed to output voltage is used to regulate current (CC)
  • Indicator : dual color indicator , charging indicator light is red , the green light means fully charged ( No load is green )
  • Output short circuit protection : Yes , constant current
  • Dimensions : 65  * 47  * 23.5  mm
 
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.)

Application:

  • High-power LED constant current driver, rechargeable lithium batteries (including ferroelectric), 4V, 6V, 12V, 14V, 24V rechargeable batteries, nickel-cadmium nickel-metal hydride batteries (battery pack) charging, solar panels, wind turbines
