Circuito Cargador Baterias Ajustable Voltaje Intensidad

  • Features:
  • 1.Fixed turn the lamp current to 0.1 times the value of the constant current
  • (charge when used to identify whether the battery is full);
  • 2. Increased input reverse polarity protection diode;
  • 3. Using dedicated reference IC, and high-precision sampling resistor, so
  • that the constant current is more stable, (20 degrees to 100 degrees, the
  • constant current 1A, when the temperature drift of less than 1%).
  • ---------------------------------------------------------------------------------
  • Particularly suitable for LED driver
  • High-power LED constant current drive
  • Lithium battery charger (including ferroelectric)
  • 4V, 6V, 12V, 14V, 24V battery charger
  • Nickel cadmium, nickel metal hydride battery pack charger
  • Solar panels and wind turbines
  • -----------------------------------------------------------------------------------
  • Specifications:
  • Module Properties: non-isolated constant current and voltage module
  • Rectification: non-synchronous rectification
  • Input voltage: 7V-35V
  • Output voltage: 1.25V-30V
  • Output current: adjustable maximum 3A
  • Conversion efficiency: 92% (the highest)
  • Switching frequency: 150KHz
  • Output ripple: 50mV (max) 20M bandwidth
  • Load Regulation: ± 0.5%
  • Voltage Regulation: ± 2.5%
  • Operating Temperature: -40 ? to +85 ?
  • ----------------------------------------------------------------------------------------
  • Battery use:
  • Make sure of the voltage and current of the battery you need to charge
  • Adjust the constant voltage potentiometer to make the output voltage same
  • to the charge voltage
  • Potentiometer Adjustment Direction: Clockwise (increase),
  • counterclockwise (decrease)
  • Use the multimeter in 10A current scale to measure output short-circuit
  • current, and adjust the current potentiometer to make sure the output
  • current to the expected charging current value
  • The charge current of transfer lamp is default 0.1 times of the charging
  • current (constant current value)
  • Connected to the battery and try to charging (for previous 5 steps, module
  • input terminal is connected to power source, output load is NOT
  • connected to batteries).
  • ------------------------------------------------------------------------------------
  • LED Constant Current Driver Use:
  • Make sure operating current and Max operating Voltage of the LED you
  • need to drive.
  • Adjust the constant voltage potentiometer to make sure the output Voltage
  • is up to LED Max operating Voltage.
  • Use the multimeter in 10A current scale to measure output short-circuit
  • current, and adjust the current potentiometer. To make sure the output
  • current to the expected LED operating current.
  • Join LED, test (For the above 3 steps, module input terminal is connected
  • to power source, output load is NOT connected to LED).
  • ----------------------------------------------------------------------------------------
  • The scope of application:
  • Charging for lithium ion batteries: when the lithium ion battery voltage is
  • low. If use the constant voltage charging directly. Due to pressure is too
  • large, leading to the battery damage. So from the beginning to use the
  • constant current charging. When charging to a certain, automatic switch
  • back to the constant voltage charging.
  • Charging curve as shown below: red is current, blue is voltage.
