When needing to easily and efficiently calculate phase frequencies, the Megger PSI410 Phase Rotation Indicator is the perfect solution. Utilizing a three bi-coloured LED display and aubible tones, the device is easy to read, easy to use and helps you to work at peak efficiency.

The device also has the ability to differentiate between different rotations. Clockwise rotation is indicated by clockwise rotating Green LEDs and a constant tone, whole counter-clockwise rotating red LEDs and a warbling tone showcase counter-clockwise rotations.

Working at a slow rotating diaplay speed, the PSI410 ensures that it does not rotate at the supply frequency, allowing easy and efficient recognition of rotation.

The LED display of the PSI410 also uses bi-colouring to help you identify when a phase is present, while a red LED indicator shows you that a phase connection is missing.
