Digital Ampmeter W/O Shunt

Measure amps and volts in 12-, 24- or 48-volt systems with these high-quality, low-cost LCD digital meters. The surface mount, 3" x 2" x 1" plastic enclosure can be attached to wood or metal surfaces with two screws. Terminal strip on the back of the meter accepts 14 to 22 AWG wire.

Amp meters are available with a 100A/100mV shunt for measuring up to 100 amps with 0.1 amp resolution, a 500A/50mV shunt to measure up to 500 amps with 1 amp resolution, or without a shunt for installations with a shunt already in place. Current draw is only 20mA. Amp meters are bi-directional, so they can be used to read loads, showing negative numbers, or to read charging sources, displaying positive numbers.

Amp meter requires 4-conductor wire; volt meter requires 2-conductor wire. Use 22 gauge or larger for up to 50 feet. Use 18 gauge for up to 150 feet. 2-year warranty.
