Megger PSI410

Megger PSI410

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.

The PSI410 also features a triple bi-coloured LED display that 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 has a tough case designed for an industrial environment and is supplied with long fused test leads with croc-clips and prods. The PSI410 is self powered from the supply and requires no batteries.
