The analogue indicator is designed to monitor AC power. This analogue indicator can be installed onto switch panels. The analogue indicator is a moving-coil ammeter. Active power as well as apparent power can be measured by means of this analogue display. In addition the measurement can be performed in single- phase or three-phase with the analogue display. Through the correspondent current- and voltage- transformer, the analogue display 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 analogue display can also measure the consumed power.
