Feature:

  • Module Properties: non-isolated Boost Buck 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 generators.
  • Solar Panel, Wind generator voltage regulator, Car Power Supply.
  • Input voltage: 4-35V
  • Output voltage: 1.25-25V
  • Output Current: Rate 3A, Max 4A ( If more than 15W, please install the heat sink, this item do not include heat sink)
  • Constant current range :0-2A (adjustable)
  • Revolving light current: constant current value * (1% -100%), Revolving light current value Linkage with the constant current value, 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 to the constant current value when the 2A, then Revolving light current is 0.2A (0.1 * 2A = 0.2A). Default 0.1 times
  • Minimum voltage pressure: 2V
  • Output power: natural cooling 15W, (if install heat sink can be 25W)
  • Conversion efficiency: 80% (the higher the output voltage, the higher the efficiency
  • Operating Temperature: Industrial (-40°c to +85°c) (if ambient temperature exceeds 40 °c, please lower power use, or to enhance heat dissipation)
  • Full load temperature rise: 45°c
  • This Converter only can rise Voltage, it can not rise Power.
  • if use Solar as power supply, please make sure the input power is 1.1 times than the output power.
Note:
  • Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease)
  • Indicator: constant current Indicator Red, Charging indicator Red, Full charge indicator Blue.
  • Output short circuit protection: Yes, constant current (constant current setting values)
  • Input Reverse Polarity Protection: None (Please Series diode at the input port.)
  • Connection: Welding, 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 3V.
  • 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 3V.
  • 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.)
Package Includes:
  • 1x DC-DC Converter
