Usage and Applications
The product is highly useful for monitoring voltage and current consumption of electronic equipment. It is perfect for building a variable voltage power supply or integrating into power systems where real-time electrical parameter monitoring is required.
The device allows two types of connections:
- Scheme 1 – common supply: the same 4–30V source powers both the voltmeter and the load
- Scheme 2 – separate supply: the voltmeter has a 4–30V supply, and the load can be powered separately (0–100V)
Advantages
- Easy to integrate into panels or project enclosures
- Clear display with good contrast even in low light
- High resolution: 0.1V for voltage and 0.01A for current
- Ideal for DIY projects, laboratories, and electronics workshops
