1. Fixed turn the lamp current constant value of 0.1 times (when charging is used to identify whether the battery is full); 2. Benchmarks using a dedicated IC, and high-precision sampling resistor, so constant and more stable (20 degrees to 60 degrees constant temperature drift 5A when less than 5%), especially for LED driven 3. Output current, maximum output current can reach 8A, to meet most needs. 4.4 High-frequency capacitance, reduce output ripple, improve stability 5. Dual heat sink design, MOS tube Schottky diodes separate heat sinks, heat, independently of each other 6. At the cost of using large-size Kool toroid, improve work efficiency, and Use copper wire and Rao, reduce heat and improve efficiency. More than 7.3296 turn potentiometer, voltage and current regulation of high accuracy, good stability. 8. High stability dedicated current sense resistor current sampling accuracy, temperature drift of small, LED essential. 9. Color indicator, working status, charging necessary. 10. Voltage and current can be adjusted, adjustable power to do good effect, 8A current, power enough. Battery charging to use: 1. Make sure you need to charge the battery float voltage and charging current, the input voltage of the module; 2. Constant adjustment potentiometer, the output voltage is regulated to about 5V. 3. 10A current with a multimeter measuring the output short-circuit current block, while the constant current potentiometer allows to adjust the output current reaches a predetermined charge current value; 4. Constant adjustment potentiometer allows the output voltage reaches the float voltage; 5. Connected to the battery, try to charge. LED constant current driver to use: 1. Make sure that you need to drive LED operating current and maximum operating voltage; 2. Constant adjustment potentiometer, the output voltage is regulated to about 5V. 3. 10A current with a multimeter measuring the output short-circuit current block, while the constant current potentiometer allows to adjust the output current reaches a predetermined LED working current; 4. Constant adjustment potentiometer allows the output voltage reaches the maximum operating voltage LED; 5. Connect the LED, test machine.

What is Bulk Rate? BulkRate is a semi-wholesale system with items priced separately from retail. When you use bulk rates, a flat $1.70 registered air mail fee will automatically be added to your cart to ensure delivery of package. While BulkRate's intention is to offer cheaper prices when you buy in bulk, because it is priced separately it on occassions show a higher than retail price. That's why we ask you to enter BULKRATE as a coupon code to manually activate the rates. You can always opt not to use the bulk rates. If you are looking for wholesale prices please feel free to contact us.
