Megger PSI410 Phase Sequence Indicator

The Megger PSI410 Phase Sequence Indicator stands out as an essential tool for electricians and technicians working in industrial environments. This self-powered device offers a straightforward method for confirming correct phase sequence, critical for the safe operation of motors, pumps, and air conditioning systems. By utilising three dual-coloured LEDs along with distinctive audible tones, users can effortlessly determine the phase rotation direction. Green LEDs signify a clockwise rotation accompanied by a continuous tone, whereas red LEDs indicate an anti-clockwise rotation with a warbling sound.

Robust Design Meets Precision

Designed with durability in mind, the PSI410’s rugged casing ensures reliability even in tough industrial settings. The unit’s intuitive LED display not only shows the phase rotation but also the presence or absence of each phase, using colour coding for clear, immediate understanding. The slow rotational lighting speed of the LEDs is a deliberate design feature to facilitate easy identification without matching the supply frequency. This, combined with long fused test leads, crocodile clips, and prods that expose less than 4mm of the tip, makes the PSI410 a model of both safety and convenience.

Key Features
  • LED indicators for clockwise and anti-clockwise phase rotation
  • Audible direction indication
  • Phase condition LED signalling for quick assessment
  • Supplied with fused test leads for enhanced safety
  • Crocodile clips and prods included for immediate use
  • Insulated prods tips for safe operation, exposing less than 4mm
  • Dual phase colour coding for universal application
  • Slow LED rotation speed for clear identification
  • Durable case suitable for industrial environments
  • Easy to use with various three-phase supplies
Technical Specifications
  • Self-powered operation for convenience
  • Dual-coloured LED display for phase and condition indication
  • Audible tone differentiation for rotation direction
  • Robust casing designed for the industrial environment
  • Long fused test leads with safety in mind
