It is a 2 in 1 Volt Amp Panel Meter, Measure Voltage Range DC 4.5-30V,Measure Current Range:0-50A forward current (need extra 50A shunt for measuring current), Accuracy: 1% (± 1 digit ),small size, high efficiency, long term stable and reliable quality,easy installation and use . Applications:LED lights measure automotive/electric cars/motorcycles battery monitoring or other products voltage current measurement.
Dual LED: Red voltage, Blue current, Display Voltage Current at same time
this panel meter is common ground design, it means that the ( measure ground wire) and (power supply ground) is common ground.
