The panel meter is designed to monitor AC power. This analogue indicator can be installed onto switch panels. The panel meter is a moving-coil ammeter. Active power as well as apparent power can be measured by means of this panel meter. In addition the measurement can be performed in single- phase or three-phase with the panel meter. Through the correspondent current- and voltage- transformer, the panel meter is able to measure higher electric power as well. This analogue indicator features an instrument panel of 92 x 92 mm. In addition to measuring the transfer of power to a load, the panel meter can also measure the consumed power.
