Review on 🔋 bayite Pack of 5 Three-Wire Calibratable DC 0~30V Red Digital Mini Voltmeter Gauge Tester: Reliable Car/Motorcycle Battery Monitor & Voltage Meter with 0.36" Red LED Display Panel by Kyle Omaha

These little meters are perfect for those little projects I can always think of that need low voltage control. Readings are surprisingly bright and clear, and the ability to turn on the display via a separate cable when needed is very handy. The image shown is intended to be vertical and shows that the AC meters are monitoring phase A and phase B of a 50A residential building input and the relevant DC meter below is monitoring the DC voltage at the output of the converter .when connected. or battery voltage if not connected. The only small issue I have is that the mounting holes are very small and close to the board which makes mounting the board careful not to short anything. The price is correct!
