Digital Phase Converter - E-Phase | Kay Industries

Congratulations! If you are reading this page, you have most likely decided to get the most voltage balanced, and quietest of all phase converters. The Perfect Phase® is the best engineered, most reliable (non-rotary) Electronic Phase Converter you can buy.

This installation page is specific to the Model PTE.

Mounting the Phase Perfect® Model PTE

  1. Attach mounting brackets to back of unit with the hardware supplied by the manufacturer with your PTE digital phase converter.
  2. It is wisest to mount the unit to a solid, non-flammable surface capable of holding a minimum of 100 lbs. using the mounting brackets provided with the PhasePerfect® PTE unit.
  3. Similar to a Phasemaster Rotary Converter, digital converters get hot. Make certain the air intake and exhaust openings are not obstructed. If mounted in a small room or cabinet, ensure temperature will remain below 40C (104F). Note: 18″ (450mm) clearance below and 6″ (150mm) around required for ventilation. Since heat rises the Model PTE Phase Perfect® is well vented on the top; see image below.

  1. Your converter comes with a warning label stating to NOT remove the outer cover. Instead you are to call Kay Industries for support. This is a note for the end-user. If you are an electrical contractor, or know what you are doing, proceed with caution.

    Powering up the Model PTE – Phase Perfect®

    1. GENTLY replace the cover and secure using the previously removed screws.
    2. Turn on the line side breaker and verify screen turns on. Note: Once the unit is fully energized the internal contactor will pull in. Once this occurs a light sizzling noise will be emitted. Good news, this is normal.

    Note: Output is in high-leg delta configuration. Leg to leg voltage will match input voltage, leg to ground will be higher on T3 than T1/T2.
