Phase sequence indicator
The Megger PSI410 phase rotation indicator provides rapid indication of correct phase sequence utilising a three bi-coloured LED display and a specific audible tone. Clockwise rotation is indicated by clockwise rotating green LEDs with a continuous tone and counter clockwise rotation has counter clockwise rotating red LEDs and a warbling tone. The unit has been designed to provide a slow rotational speed of the display to allow easy recognition of the direction of rotation. Dual phase colour coding has been adopted for the PSI410 to allow ease of use on both Brown / Black / Grey and Red / Yellow / Blue colour coded supplies.

Combined Voltage Detector and Phase Rotation Indicator
The APPA VP-2 combines a high functioning volt stick with a RED/GREEN phase rotation indication. The voltstick flashes more quickly the stronger the voltage signal, simplifying live voltage identification in a crowded circuit board or cable run.
