DC-DC Automatic Step UP/Down Converter Boost/Buck Voltage Regulator Digital LCD Display Power Step-down Module 0.2-3A Adjustable

SKU: SLY3851 Category: Others

Product Description

Features:

1. The LCD can display input and output voltage, output current and output power.

2. The module has reverse input protection. (please try not to connect input reversely. There is + – marks on board that you can check before wiring)

3. It can step-up and step-down, output voltage is adjustable within 0.5-30V, limit current is adjustable within 0.2-4A.

4. Output has flow back protection, do not need to add flow back protecting diode when it is used to charge battery.

5. Use button to control output ON/OFF state, and can set default as ON or OFF when powered.

6. It uses step up/down chips as main controller, external 60V 75A MOS tube as switch tube, double 60V 5A SS56 schottky as rectifier, withstand 60V voltage, better tjam XL6009/LM2577 immature solutions.

7. The output ripple is small, and have the LC filter.

Specification:

Type: 4A non-isolated step up/down constant current power supply module
Input Voltage: 5.5-30 VDC (at 5V input, it can also step up down voltage, but the voltage current measurement is inaccurate; when lower than 4.7V, under-voltage protection)
Output Voltage: 0.5-30VDC adjustable
Output Current: 0.2-3A adjustable, enhance heat dissipation can be up to 4A (please enhance heat dissipation when module temperature is over 65℃) with constant current indicator light, output power do not exceed 35W;
for low voltage output, current do not exceed 4A, otherwise it will burn out.
Voltage Display Resolution: 0.05V
Current Display Resolution: 0.005A
Conversion Efficiency: About 88%
Soft Start: Yes (it may fail when big power load module start)
