Run three phase imported machinery from 415V Australian mains power
Custom made three phase units:
500VA - 150KVA
Open style or enclosed
These units convert three phase voltage allowing you to power imported equipment from Australian 3Ph 415V mains power.
We custom manufacture three phase auto and isolation type transformers suitable for stepping up or stepping down any international voltages.
Ideal for import / export machinery
Suitable for all types of equipment
Durable powder coated steel enclosures
Many configurations available with plugs and outlets
An example would be a machine imported from China, three phase power in China is 380V, here ours is 415V. In this case a three phase step down transformer (415V - 380V) would be needed to run this machine.
Calculating the correct VA rating for a 3Ph transformer
Before ordering a three phase transformer, first we need to determine the rating of your equipment. This will normally be marked on the back of the machine, on a rating plate, or in the instruction manual. It will be given as Amps (A) or Watts (W).
Now, we multiply the Amps by the voltage and then by (square root of 3), ie. 220V x 10A x 1.732 = 3810VA (This is the most reliable method for calculating total input power).
However, sometimes only the Watts are given, in this case we divide Watts by 0.85, ie. 5000 W / 0.85 = 5900VA approx.
With the correct equipment rating in VA, you can confidently order a transformer to suit. In most cases, a three phase transformer will be hard wired to the machine (ie. no plugs or sockets). Always get a qualified electrician to do the wiring.
