Product Description: It is a 15W Adjustable Voltage Regulator/Power Supply Module/Charger/Adapter, Input voltage: DC 7~35V, Output voltage: DC 1.25~30V adjustable, Output Current: 3A, Application: DIY Power adapter/Charger, industrial equipments, electronic equipment, Communications Equipment, Power Tools, Car Driving Recorder, Car GPS, Car audio, LCD TV, Advertising screen, Monitoring System, LED lights, Fan, intercom and monitor system, etc.

Features:

  • 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 °c to +85 °c) (ambient temperature exceeds 40 °c, lower power use, or to enhance heat dissipation)

  • Full load temperature rise: 45 °c

  • 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 °c to 100 °c, 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

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: DC 7~35V,

  • Output voltage: DC 1.25~30V adjustable

  • Output Current: 3A (more than 15W, please install heat sink, this item do not include 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

  • Case Color: Silver or Black, will be sent random color

Battery Charging method:

  • Make sure the recharge battery float voltage and charge current, input voltage of the module.

  • adjust constant voltage regulator, the output voltage about 5V.

  • With a multimeter ( to 10A) Measuring output Short-circuit current, Also adjust the constant regulator allows Output current reaches a predetermined charge current value;

  • Adjust Constant regulator allows Output voltage reaches the float voltage;

  • Connected to the battery, try charging. (1,2,3,4 step input connect power, output do not connect battery.)

LED constant current driver Usage:

  • Make sure LED current and the maximum operating voltage;

  • Adjust constant voltage regulator, the output voltage about 5V.

  • 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;

  • Adjust Constant regulator allows Output voltage Reach LED maximum working voltage;

  • Connected to the LED, test. (1,2,3,4 take steps input connect power, output do not connected LED.)
