DC DC ADJUSTABLE VOLTAGE STEP UP & STEP DOWN / CURRENT IN CAPE TOWN

DC-DC Adjustable Voltage Step up & Step Down / Current Driver/ Charger: Description: 1piece of DC-DC adjustable step up/ step-down (Voltage & Current) power supply module Input Voltage: 5-35V Output Voltage: Continuously adjustable from 1.25 V to 30V Rated Output Current: 3A Max. Output Current: 4A (more than 15W, preferably with a heat sink) Size (L x W x H): Approx. 1.9 x 0.95 x 0.5 inch / 4.8 x 2.4 x 1.3cm Indicator Light Constant current indicator(red) Charging indicator(red) Charged full (green) Applications: 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 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)
