The A 220 A 210 power measuring instrument is suitable for control panel mounting and measures all the
important measurands in 3-phase and single-phase systems.
It displays the measurands with a high contrast 14 mm high LED display.
The instrument is also suitable for measurements in low and middle voltage systems because of the freely
programmable factors for the current and voltage transformers.
It replaces a large number of analog instruments and delivers high accuracy values.
