Thank you to all who have replied to this topic. I have now imported and installed the PT330 Phase Perfect phase convertor and it is working perfectly, in fact far more efficiently that the old static and rotary types generally found in the UK. As the output voltage of the convertor was designed...

Late evening in England and my brain is in turmoil! Notwithstanding the excellent advise I am receiving in these threads and bearing in mind that I am about to send a payment of $3100 to purchase the Phase Perfect PT330, I do need full assurances from Phase Perfect that this unit will connect...

Hi Jim Just one comment before I digest you full reply - The UK house supply is Line (230V), Neutral (0V) and protective Earth. I appreciate that the N is probably grounded or Earthed by the supplying utility at their district transformer but never by the user. Does this affect your main...

Good morning Jim First let me clarify the UK domestic supply system. At street level the supply utilities distribute 3 phase, 415V ac power, a neutral, the protective Earth is provided either by ground spikes or via the utilities armoured cable sheath. Each phase to neutral provides 230V...

YES! and I went to school with A. Einstein but he grabbed all of the brains! On this link xxx.phaseperfect.com/techinfo.htm "Operation and Installation Manual - PT Series" diagram 6 shows a diagrammatic of the US electricity grid supplying 120V x two to L1 & L2 of the converter - I presume...

Hi Jim Just found this on another site and it seems to clear the fog on my understanding of the US power system but not how Phase Perfect create 3 Phase. Thanks Frank Wiki: A split phase electricity distribution system is a 3-wire single-phase distribution system, commonly used in North...

Hello Jim Surely not that old! I will check the motor kVa - I note that this converter accommodates a 4 second overload of 150A. One final question (I hope) Can you open the following link (phaseperfect.com/files/op_inst_pt.pdf) and look at Fig. 6; my limited electrical knowledge seems...

Thank you for your reply. My motors are dual voltage and can be changed from 415V to 230V 3 phase.

My home workshop has three woodworking machines, all fitted with dual voltage 3 Phase motors, currently configured for 415V 50Hz. My workshop power supply is 230V single phase 50A. I have been using a static converter to provide the three phase but I would now like to upgrade to a digital phase...
