5A DC-DC 4-38V to 1.25-36V CC CV Step Down Module LED Drive Battery Charger Description 1.Input voltage:5-38VDC 2.Output voltage:1.25-36VDC adjustable 3.Output current: 0-5A adjustable 4.Output power: 75W(MAX) 5.Operating temperature:-40~+85℃ 6.Frequency:180KHz 7.High efficiency up to 96% 8.Short circuit protection:Yes(limit current 8A) 9.Overtemperature protection: Yes(automatically shut off the output after overtemperature) 10.Input reverse polarity protection: None (if required, high current diode in series with the input). 11.Installation: four 3mm screws 12.Connection: terminals or solder terminals, V-IN is the input, V-OUT output 13.Module dimensions: length 61.7mm width 26.2mm height 15mm 14.Weight: 25g Note: 1.When you use the product, the module input and output to be isolated from ground. 2.The output of block string has a current sampling resistor, there will be 0 ~ 0.2V voltage drop after connected to the load, it is normal. 3.This module exceeds 3A, 35W in use,please enhance heat dissipation. 4.Some customers report: “The module can not adjust the output voltage is always equal to the input voltage.” When you encounter this problem, please counterclockwise rotation of the “voltage potentiometer” 10 laps or more, then use the module you can adjust the output voltage. Because the factory default output voltage of about 20V. Applications 1.Use as a step-down module with overcurrent protection Usage: (1) Adjust the right button so that “OUT” LED lighted, Digital meter shows the value of output voltage ,adjust the “voltage potentiometer” so that the output voltage reaches the value you want. (2) Adjust the right button so that Digital meter shows the value of output current;Wire shorted output terminal, then adjust the “current potentiometer” so that the output current reaches a predetermined overcurrent protection value. (For example, the Digital meter displays the current value of 4A, then you can use the module to a maximum current of 4A) (3) Connected to the load. 2.Use as a battery charger Module without constant function can not be used to charge the battery, since the power consumption end of the battery and charger have big voltage difference,resulting in charging current is too large, causing cell damage, so start to the battery using a constant current charging, when charging to a certain extent then automaticly switch back to constant voltage charging. Usage: (1) Make sure you need to charge the battery float voltage and charging current; (if lithium parameters 3.7V/2200mAh, then the float voltage is 4.2V, the maximum charging current 1C, ie 2200mA) (2)Under no-load conditions, adjust the “Voltage potentiometer” so that the output voltage reaches the float voltage; (if to 3.7V rechargeable lithium battery, the output voltage can be adjusted to 4.2V) (3)Adjust the right button so that Digital meter shows the value of output current;Wire shorted output terminal, then adjust the “current potentiometer” so that the output current reaches a predetermined Charging current value. (4)Charge turn lamp current factory default is 0.1 times the charging current; (Battery during charging current is gradually reduced, if the charge current setting is 1A, then when the charge current is less than 0.1A, blue lights turned off, the green light is on, which means that the battery is fully charged) (5)Connected to the battery charge. (1,2,3,4 steps as: Output is unloaded, do not connect the battery) 3.Use as a LED constant current driver module Usage: (1) Determine the work you need to drive the LED current and the maximum operating voltage; (2) No-load condition, the digital meter is adjusted to [displays the output voltage] interface, adjust the "constant potentiometer" so that the output voltage reaches the LED operating voltage; (3) Digital table is adjusted to show the output current,direct shorted circuit the module output (find thick wire shorted circuit output terminals), then adjust the "constant current potentiometer" to make digital sheet LED current value reaches the preset operating current; (4) Connected to the LED, the test machine. (Step 2, 3 :the input is connected supply power and output load is not connected LED lights) Package included: 1 x 5A CC CV Buck Module Payment We only accept PayPal.
