Phase sequence display DT 901, CAT IV with LCD-display

The Elma DT 901 is a security phase sequence / rotation direction indicator with a large clear LCD display instead of the traditional LEDs. The display is very easy to read, even in sunlight. Shows both the phases and the direction of rotation. Note that the instrument does not show the direction of rotation in case of wrong connection (eg two phases and
zero) but only when three phases are connected. The instrument is equipped with an integrated rubber hood.
