Λεπτομέρειες

Input Voltage: 5-35V
  • Rated Output Current: 3A
  • Output Voltage: Continuously adjustable from 1.25 V to 30V
  • The dropout voltage: 1.5V, because of reducing module, in order to ensure the output steady. Please keep the minimum 1.5V pressure difference.
  • This product with the charge constant current indicating lamp, the charge indicator lamp, lamp current adjustable ultra small volume.
  • Size: 48mm (L) *24mm(W) *11.4mm(high), not containing potentiometer (including the potentiometer height 13mm).
  • Module nature: Non isolated step-down constant current. Constant voltage module (CC CV). Charging module.
  • Scope of application: High power LED constant current drive, Lithium battery charging (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charge, NiCd and NiMH battery(batteries) charge, solar panels and wind generators.
Output voltage:
    • Adjustable continuously (1.25-30V adjustable).
    • Requires fixed output (between 1.25-30V arbitrary choice).
  • Adjustable mode: Connect the power correctly(7-35V), and then monitor the output voltage use multimeter, and potentiometers (generally, clockwise turn boost, inverse to buck).
  • Output voltage: Continuously adjustable (1.25-30V load regulation).
  • Maximum output current: 3A, (more than 15W install fins please).
  • Turn lamp current: constant current value * (1% - 100%), turn lamp current and constant current value linkage, such as constant current value is 3A, turn lamp current set to 0.1 times of the constant flow (0.1*3A=0.3A), when the value of the constant current regulation into 2A, then turn the lamp current is 0.1 times of the constant flow (0.1*2A=0.2A).
The dropout voltage: 2V
  • Output power: Natural cooling 15W
  • Efficiency: 92% (maximum 92% (the higher the voltage, the higher efficiency)
  • Output ripple: 20M bandwidth (only for reference)
  • Input 12V output 5V 3A 60mV (MAX)
  • Working temperature: industrial grade (-40 ? to +85 ?) (environmental temperature exceeds 40 degrees, please reduce power use, or to strengthen dissipate heat).
  • Full temperature: 45 ?
  • The no-load current: typical 10mA (12V 4.2V)
  • Load regulation rate: + 1%
  • Voltage regulation rate: 0.5%
  • The dynamic response speed: 5% 200uS
  • Indicator: Constant flow indicator light is red, charging light is red, after charging indicator light is blue.
  • Output short circuit protection: Yes, constant current (setting the value of the constant current).
  • Connection: Wire can welded in PCB directly.
Battery charging methods:
  • Determine the float voltage and charging current that you need to charge battery and module's input voltage.
  • Adjustable constant potentiometer, the output voltage is regulated to about 3V.
  • Use multimeter 10A current block measurement output short circuit current, meanwhile adjusting the constant current potentiometer to make output current reaches predetermined current value.
  • The charging turn lamp current default is 0.1 times of charging current (current value ).If you need, adjust turn lamp current potentiometer please (generally do not adjust).
  • Adjustable constant potentiometer to make the output voltage to the floating charge voltage.
  • Connect battery, to try charging (1, 2, 3, 4, 5 steps is the module input power, output no-load not connected to the battery).
LED constant current driving use methods:
  • Determine you need to drive LED operate current and maximum working voltage.
  • Regulation constant potentiometer; 2, the output voltage is regulated to 3V.
  • Use multimeter 10A current block measurement output short circuit current, meanwhile adjusting the constant current potentiometer to make output current reaches LED operating current.
  • Adjustable constant potentiometer to make the output voltage to the LED maximum working voltage.
  • Connected to the LED, try test machine. (1, 2, 3, 4 steps is the module input power, output no-load not connected to the LED lamps).
