Item Description: Update content: 1.Fixed turn the lamp current to 0.1 times the value of the constant current(charge when used to identify whether the ... morebattery is full) 2. Increased input reverse polarity protection diode; 3. Increase the output of a backflow preventing diode to prevent when the electricity to charge the battery back in; 4. 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 ℃ Size: 48* 23* 14(L* W* H) mm) Battery use: l Make sure of the voltage and current of the battery you need to charge l Adjust the constant voltage potentiometer to make the output voltage same to the charge voltage l 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 l The charge current of transfer lamp is default 0.1 times of the charging current(constant current value) l 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: l Make sure operating
