0-100V DC Voltmeter

Compact digital DC voltmeter with bright 0.28-inch LED display for accurate voltage monitoring in automotive, solar, battery, and electronics projects. This three-wire voltmeter provides real-time voltage readings from 0 to 100V DC with high visibility red LED digits that can be read from a distance. The panel mount design features a small footprint, making it perfect for tight dashboard installations, power supply monitoring, battery banks, and DIY electronics enclosures.
Three-wire design separates power supply from voltage measurement input, allowing for safer and more accurate readings across different voltage ranges. Featuring reverse polarity protection and stable readings, this voltmeter is ideal for monitoring 12V/24V/48V systems, solar charge controllers, UPS systems, and electric vehicle batteries. The sleek black housing with clear display window provides a professional appearance for any project. Accurate to ±1% with automatic decimal point placement for easy reading.
