These high-quality, low-cost LCD digital meters display amps and volts in 12-, 24- or 48-volt systems. The surface mount, plastic enclosure is 3" x 2" x 1" and can be attached to wood or metal surfaces with two screws. A 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, and a 500A/50mV shunt to measure up to 500 amps with 1 amp resolution. The meters are also available 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; 18 gauge up to 150 feet. 2-year warranty.
