Specification:

 

The scope of application:

1) Can use as normal step down voltage regulator with current limit function.
2) Use as constant current regulator.
High power LED constant current driver, rechargeable lithium batteries (including ferroelectric),

battery, NiCd and NiMH batteries (battery) charging, 4V, 6V, 12V, 14V, 24V, battery charging,

24V 19V laptop battery and so on solar panels, wind turbines.

the application scope is very wide.

 

Feature:

Module : 8A constant voltage constant current buck converter

Module Properties: non-isolated step-down module (BUCK)

Input Voltage: DC 7-32V(input>12V, the output can be constant current)

Output voltage: DC 1.25-28V continuously adjustable

Input>output 1.5v

Output current range: 0.3-8A(Max 10A)

Turn light current: constant current value * (0.1),

such as the constant current value is 3A, Turn light current is set to constant current of 0.1 times (0.1 * 3A =

0.3A), when adjusted constant current value to 2A, then Turn light current is constant current of 0.1 times (0.1 *

2A = 0.2A). this version is 0.1 times fixed

Operating temperature: -401C to +651C

Operating Frequency: 300KHz

Conversion efficiency: Up to 95% (efficiency depnd on the input and output voltage, current, pressure)

Short circuit protection: Yes (Limit the current to the set current value)

Function 1: Charging Battery

Step 1: make sure the battery float charging voltage and charging current, input voltage:

Step 2: adjustable constant voltage (CV) potentiometer, regulate the output voltage to 5V.

Step 3: with a nuultimeter(2(IA current block) measure the output short circuit current, regulate current potentiometer (CC), so that the

output current reaches a predetermined charging current value:

Step 4: adjust the potentiometer, so that the output voltage reach the floating charge voltage.

Step 5: connected to the battery, charge.

(1, 2, 3, 4, step input module connected to the power supply, the output not connect battery. )

Function 2: LED Constant Driver

Step 1: make sure the LED working current, max working voltage:

Step 2: adjustable constant voltage (CV) potentiometer, regulate the output voltage to 5V.

Step 3: with a multimeter(20A current block) measure the output short circuit current, regulate current potentiometer (CC), so that the

output current reaches a predetermined LED working current value:

Step 4: adjust the potentiometer to the output voltage to the LED max working voltage.

Step 5: connected to LED and power supply

(1, 2, 3, 4, step input module connected to the power supply, no connect LED)
