## Description

Adjustable step-down module, ideal for a stable DC source up to 6A, 7-32V input and 0.8-28V output, maximum power 150W with efficiency up to 95%. Fine adjustment of voltage and current from potentiometers, output short-circuit protection and low ripple for sensitive applications. Suitable for battery charging, LED driver and compact laboratory power supply.
The ideal module to create an adjustable 6A step-down voltage source.
Specifications:
Input voltage: 7 - 32V DC
Output voltage: 0.8 - 28V DC
Minimum difference between input and output voltage: 1V
Output current: 0.2 - 6A (if temperature exceeds 65 degrees, adding a fan is mandatory)
Maximum output power: 150W
Maximum efficiency: 95%
Operating frequency: 300KHz
Ripple Input 24V, Output 12V, 5A: 50mV
Output short circuit protection: Yes
Input polarity protection: None
No-load current: 20mA
Adjustable output current: ± 1%
Adjustable output voltage: ± 1%
Current and voltage adjustment method: via the two potentiometers; turning clockwise increases voltage and current, counterclockwise decreases them
Operating temperature: -40 - +80 °C (high temperatures require active cooling)
Dimensions mm: 65 x 47 x 22mm
2-color LED indicator: red indicates battery charging in progress, green indicates the battery is charged (no further current consumption).
This module can be used for battery charging. The change in charging current measured under temperature conditions between 25 and 60 degrees C is less than 5% when set to 5A.
The module can be used for:
- LED power driver
- Lithium and lead battery charging
- Adjustable laboratory power supply
- Device power supply (laptop)
For battery charging, make sure that the voltage and charging current are those specified for the battery.
