Volt and Amp Meter with Shunt - 100 AMP

Description 100A Volt and Amp Panel Meter with Shunt Measure Voltage Range DC 0-100V Operating voltage:DC 4.5 ~ 30V Minimum resolution(V): 0.1V Measure Current Range 20-100A forward current Minimum resolution(A): 0.1A Accuracy: 1% (± 1 digit ) Operating voltage:DC 4.5 ~ 30V Operating current: <20mA Dimensions: 48 x 29 x 21mm Mounting cutout: 45.5 x 26.5mm Refresh rate: about 500mS / times Operating temperature: -10 to 65° c Operating Humidity: 10 to 80% (non-condensing) NOTE: These Amp meters are more accurate towards the upper end of the range. Do not buy a 100Amp meter if you intend to measure 1 Amp, it will not work. If you will measure low amps like a camping fridge (typicaly 5 to 8 Amp), rather opt for the 20 Amp unit.
