DROK Digital Multimeter Dual LED Display Voltmeter DC 4.5V to 30V Ammeter 0 to 50A Voltage Current Meter Volt Amp Panel Monitor for Auto Car Motor
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.
Power Supply DC 4.5-30V. With reverse polarity protection, but the max power supply can not exceed 30VDC.
Power Supply (Measure Voltage): DC 4.5-30V
voltage < 10V, resolution: 0.01V
voltage >= 10V, resolution: 0.1V
Measure Current: 0-50A forward current (need an extra 50A shunt for measuring current)
Current Resolution: 0.1A
