• • 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
• • 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)
• • 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)
• • 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)
