2pcs DC 100V 10A Voltmeter Ammeter LED Dual Volt Amp Meter Voltage Current Gauge

Simultaneously monitor DC voltage up to 100V and current up to 10A
Auto ranging 0.01V 0.01A precision • ±0.1% voltage tolerance • ±1% current tolerance • Working current: Size: 48x29x22mm • Hole size: 46x27mm • calibration potentiometers for both voltage and current
Operating Temp: -10℃ – 65℃ • DC only, not for use with AC • 4-28V supply voltage
Note: If the meter supply voltage (thin red wire) is the same as the load, then it must only be used with 4-28V or the meter may be damaged
