Blue Sea 8022 DC Analog Ammeter - 0-50A Range

The Blue Sea Systems 8022 DC Analog Ammeter reads 0A to 50A on a 2-3/4 inch face, supplied with the required DC shunt.

The shunt comes in the package, which is worth noting since an ammeter without one is an incomplete purchase. The shunt takes the actual current while the meter reads only a small signal across it, so the heavy cable never has to reach the panel face.

Fifty amps suits a smaller charging system or a moderate load circuit, where a 150A meter would leave the needle barely moving. Matching the range to the actual current is what makes an analog meter readable. Too wide a range and normal operation looks like zero.

A simple two-wire connection handles both the sensed signal and meter power, which keeps the installation straightforward. The 2-3/4 inch face gives the scale room to stay readable from a normal panel distance, and backlighting lets it match other illuminated instruments at the helm.
