5A DC to DC CC CV Step Down Module

Product Description

1. High power, high efficiency,5A,low ripple;

2. Three major functions:

(1) as a general step-down module with overcurrent protection capability;

(2) as a variety of voltage lithium batteries, nickel-cadmium nickel-metal hydride batteries Charger used for solar panels,wind turbines and other occasions;

(3) as a high power LED constant current drive module used;

3. With constant voltage and constant current mode, the indicator light indicates which mode;

4. As a lithium battery charger to use,you can set the float voltage and charge current Small, indicating whether the indicator is being charged or filled;

5. With current limiting protection function,even if the output short circuit will not burn the module.

Product Applications

1.As an overcurrent protection step-down module

(1) adjust the "voltage potentiometer" so that the output voltage reaches the value you want;

(2) use a multimeter to measure the output short-circuit current with 10A stalls, while regulating the "current potentiometer" so that the output current reaches a predetermined

overcurrent protection value.(For example, the 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

(1) Make sure you need to charge the battery float voltage and charging current;(f 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) use a multimeter to measure the output short-circuit current with 10A stalls, while regulating 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, then green light is on, which means that the battery is fully charged).

(5) connected to the battery charge.

3.As LED constant current driver

(1) adjust the" voltage potentiometer "so that the output voltage reaches the value you want.

(2) use a multimeter to measure the output short-circuit current with 10A stalls, while regulating the "current potentiometer "so that the output current reaches a predetermined LED

operating current.

(3) Connect LED, work.(1,2 steps as: Output is unloaded, do not connect LED).
