5A Constant Current LED Driver Module & Battery Charger - Red
This SKU 433947 is available in DXSOUL with Free Expedited delivery. DXSOUL: 901433947
When you use this product, the module input and output to the ground and do not co-together, this will cause the board high-power current sense resistor is bypassed, so that the module can not adjust the output current size, then it is easy to burn power chip module.
The module is easy to use, powerful! ! ! A module has three major features to meet your vast majority of occasions! ! !

Module Highlights:
1. High-power, high efficiency, 5A, low ripple;
2. 3-in-1:
(1) Used as an ordinary step-down module with overcurrent protection capability;
(2) As various batteries charger for solar panels, wind turbines and other occasions;
(3) Used as high-power LED constant current driver module.
3. With constant voltage and current modes, the indicator light indicates which mode the module is currently in;
4. When using as a lithium battery charger, you can set the float voltage and charge current; It is shown being charged or has been fully charged;
5. The current limiting protection, short circuit will not burn the module.

Installation: four 3mm screws
Connection: wiring terminals or soldering terminals, V-IN is the input, V-OUT it the output
Module size: 15mm long, 51mm wide and 26mm high
Weight: 18g

Application
1. Used as an ordinary step-down module with overcurrent protection capability
Instruction:
(1) Adjust the regulation potentiometer to make the output voltage reaches the value you want
(2) Use 10A current mode to measure the output short-circuit current file (directly to the two leads to the output can be), while adjusting the constant current potentiometer allows the output current reaches a predetermined overcurrent protection value. (Such as the current value displayed on the multimeter is 4A, then you can use the module to a maximum current of 4A, 4A current to the constant voltage constant current when the red indicator light, otherwise light off)
Note: When used in this state, since the output of 0.05 ohm current sense resistor, there will be 0 ~ 0.3V voltage drop after connected to the load, this is normal! This drop is not being pulled down your load, but down-sampling resistor.
2. Use as a battery charger
Without constant function module can not be used to charge the battery, due to the complete consumption of the electrical battery charger with big difference between charging current is too large, resulting in damage to the battery, so start to the battery using a constant current charging, when charging to a certain extent automatically switch back to constant voltage charging.
Instructions:
(1) determine that you need to recharge the battery float voltage and charging current; (lithium parameters if 3.7V / 2200mAh, then float voltage of 4.2V, the maximum charging current 1C, namely 2200mA)
(2) under no-load conditions, the multimeter to measure the output voltage, the constant voltage potentiometer to adjust the output voltage reaches the float voltage; (if to 3.7V rechargeable lithium battery, the output voltage can be adjusted to 4.2V)
(3) with a multimeter 10A current range measuring output short-circuit current (directly to the two leads to the output can be), while adjusting the constant current potentiometer allows the output current reaches a predetermined charge current value;
(4) Charge turn lamp current factory default is 0.1 times the charging current; (Battery during charging current is gradually reduced, gradually converted to constant voltage charging by the constant current charging, if the charging current setting is 1A, then when the charging current is less than 0.1A when the blue lights off, the green light is on, then the battery is fully charged)
(5) connected to the battery charge.
(1,2,3,4 steps as: termination power input, the output of load cell is not connected)
3. Use a high-power LED constant current driver module
(1) determine that you need to drive the LED operating current and the maximum operating voltage;
(2) no-load condition, the multimeter to measure the output voltage of the constant voltage potentiometer to adjust the output voltage reaches the LED maximum working voltage;
(3) 10A current with a multimeter to measure the output short-circuit current gear while adjusting the constant current potentiometer allows the output current reaches a predetermined LED operating current;
(4) connected to the LED, the test machine.
(Steps 1 through 3 are: power supply input connected to the output load is not connected LED lights.)

Note: This module is more than 3A, 35W in use, to enhance heat dissipation! ! !

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.
