Megger PSI410 Phase Sequence Indicator

Commercial and industrial installations often require working on motors with three phase supplies. Correct sequence of the phases is important as damage to brakes and valves will occur rapidly if incorrect phased.  PSI410 phase rotation indicator provides indication of correct phase sequence using a three bicoloured 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.  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.

The PSI410 indicates that all three phases are present.  A green LED indicates the phase is present while a red LED shows a missing phase connection. The unit is tough and is supplied with long fused test leads with croc-clips and prods.

Megger PSI410 Applications:
