Features
1. Fixed turn lamp current is 0.1 times the current value( Used to identify whether the battery is fully charged When charging).
2. Made from a dedicated benchmark IC and high-precision current sensing resistor, proving a more stable
constant current, (when 20°C to 100°C constant current 1A, temperature drift less than 1%). Particularly suitable for LED driver.
3. High output current, the max output current can reach 8A.
4. Four high frequency capacitance, can lower output ripple, enhance the work stabilization.
5. Double heat sink design. MOS schottky diode independent heat sink,which heat dissipation is good, and won’t affect each other.
6. Using large size Sendust Core and double pure copper wiring, improve working efficiency, reduce fever.
7. 3296 multiturn potentiometer,high accuracy voltage and current regulation, good stability.
8. Double color lamp, working condition be clear at a glance
9. Voltage and current are adjustable,wich effect is good.
Applications
1. High-power LED driver.
2. Lithium battery(or lead accumulator) charge.
3. Vehicle-mounted power supply.
4. Low voltage system power supply.
5. 6V, 12V, 14V, 24V battery charge.
6. On-board laptop power supply.
7. regulated power supply.
8.Low voltage power supply system.
Module adjustment
1. When the module output voltage can not be adjusted (the output voltage is always equal to the input voltage) Please adjust the potentiometer counterclockwise 20 laps (20 turns) or more till it works.
2. Turn trimmers CLOCKWISE to INCREASE, ANTICLOCKWISE to DECREASE.
3. When adjust the blue potentiometer ,please use a multimeter to monitor the voltage
4. The trimmer nearest the voltage output adjusts the output CURRENT (CC)
5. The trimmer nearest the voltage input adjusts the output VOLTAGE (CV)
Charger application – intructions
1. First determine the float voltage and charging current required by the battery to be charged (the ‘target battery’). The target battery disconnected from the module output, apply a voltage of 7V – 32V to the module input, being sure to observe correct polarity.
2. Using the CV trimmer, adjust the output voltage to about 5V.
3. Switch your multimeter into its 10A current scale and measure the module’s short-circuit output current. Turn the CC trimmer to adjust the current to the charging current required by target battery.
4. Using the CV trimmer, adjust the module’s output voltage to the float voltage required by the target battery.
5. Connect the target battery to the module output, observing correct polarity. Charging of the battery should commence
Constant current LED Driver Application – Instructions
1. First determine the operating current and maximum operating voltage of the LED you need to drive.
2. With the CV trimmer, adjust the output voltage to about 5V.
3. Switch your multimeter into its 10A current scale and measure the module’s short-circuit output current. Turn the CC trimmer to adjust the current to the operating current of your LED.
4. Adjust the CV trimmer to make the output voltage reach the maximum LED operating voltage.
5. Connect LED, test.
