Three Phase American Step Down Transformer
Note: If you require custom made three phase transformers please see here.
3 Phase American Step Down Transformer – Three Phase Step Down Auto-transformers (also referred to as voltage converters) are designed to convert an input of 415VAC (Australian power grid voltage) through the transformer to an output of either 200VAC and 220VAC (transformer has two outputs taps to allow for 200VAC and 220VAC).
With two output taps from the transformer, you can choose which voltage output you require depending on what voltage your appliance requires (if it is an American or Japanese machine). These Three Phase Step Down Transformers are rated in either 10kVA and 30kVA, and are an ideal solution if you want to run an Overseas device rated at 200VAC or 220VAC in Australia. They also can be used for multiple purposes including Industrial and Commercial machines/appliances.
For Step Down 380V Transformer for a European/Chinese or Korean Industrial Machine Conversions, see here. For Three Phase 415/415VAC Isolation transformers, please click here.
Please Note: Transformers must be hard wired into the electrical supply by a Licenced Electrician or Electrical Contractor. These items are mainly for Industrial & Factory environments with high current input supply, not for domestic use (unless specified by Electrician or Tortech Engineers).
- A three phase transformer is the ideal solution if you want to run an overseas device NOT designed for the Australian 415VAC mains supply.
- The transformer will convert 415VAC into 200V or 220VAC to allow your USA overseas equipment to work here in AUSTRALIA.
- We stock these three phase transformers for all Countries and Voltages. For a custom three phase step down transformer, please enquire here.
- Custom step down transformer as mentioned above can be manufactured as Dry Type Indoor or Outdoor Auto transformer units rated up to 1000kVA (2886.83A @ 200vac)
- These items are mainly for Industrial & Factory environments with high power capacity, not for Domestic use. Single Phase transformers used for domestic use are listed here.
- They must be Hard Wired into the Electrical supply by a Licensed Electrician or Electrical Contractor with a suitable circuit breaker.
- Insulation class of materials used is Class F (155ºC) or Class H (180ºC).
- The units are natural convection cooled and require suitable clearance around the transformer.
- The in-stock transformers are enclosed in indoor type (IP22), but Tortech can manufacture a new custom transformer which can be either open style or an outdoor enclosure type (IP56) in materials such as Epoxy polyester powder coated mild steel.
- Stainless steel enclosures are also available for our transformers in marine grade SS316 material suitable for installations with high salt/corrosion content.
- Ring Stud terminals are used for these transformers. Our custom transformer designs can be either a DIN rail mount blocks/standard terminal blocks or bus bars (depending on the current rating of the transformer).
NOTE: A transformer will only step the voltage up or down depending on its ratio. It will not change the frequency from 50Hz (cycles) to 60Hz. American motors are designed to operate at 60Hz and will be reduced in capacity/speed by around 20% when running on 50Hz supply. However, Tortech transformers have a reduced voltage of 208vac instead of 220vac to compensate the difference in frequency.
About Us:
- Tortech has over 30 years of experience in customised transformers for the defence, transport, mining and the renewable energy industry.
- Tortech transformers can be supplied with routine test reports and special type test reports.
- Tortech has an ISO9001 quality management system in place to ensure that we minimise errors and increase the reliability of our units.
- Tortech offers excellent pre-sales and after sales support, feel free to contact one of our friendly sales staff on (02) 9642 6003.
- American step down transformers are generally manufactured as Auto-transformers and do not provide electrical isolation.
- Auto transformers are compact and approx half the size of isolation transformer (415/220VAC).
- We can also supply the transformers for OEM equipment. We offer special discounts on bulk orders.
- Please visit our isolation transformer page for info on custom made isolated step down transformers.
- Transformers are manufactured with aluminium wire and are rated for operation in harsh Australian conditions.
- Our designs are generally based on an ambient temperature of 50ºC, <1000m elevation and <99% Relative humidity (Non condensing).
- We have extensive experience in R&D and have engineers dedicated to the research on "Temperature rise of dry type transformers", "Partial Discharge and short circuit strength of epoxy resin cast transformers".
- We have been conducting presentations on the topic at various Australian universities and Engineers Australia Sydney division.
- Tortech has been studying the distribution of forces, fields and heat flux on our transformers using Finite Element Analysis (FEA software).
- This has helped us to manufacture special transformers for the defence and research community.
Why Us:
- Our Transformers are of the Highest Quality. Design life of 25 years.
- All our Units come with a 1 Year Money Back Warranty!
- Local pre-sales and after sales support.
- Tortech is fully equipped with testing equipment calibrated by an accredited NATA laboratory.
- Isolated input to output versions are available.
- We can quote and install a Safety Fuse or Circuit Breaker Protection upon request.
- Transformers can be specially manufactured for installations with low in-rush current requirements.
- GOSS, NON GOSS, Uni-core and Amorphous core designs are available for special applications.
- Enclosed or Open units. Enclosures made with powder coated mild steel or stainless steel.
- Australian and overseas manufactured units are tailor made to suit extreme Australian conditions.
To Help determine which Transformer you will need, please check these questions first:
What is the total watts or VA used by the appliances to be connected to the Transformer?
Select from our range below, based on how many watts your device uses
Choose the unit with matching power rating or the next one up.
Most appliances have a rating label on them.
E.g: If your device uses 5150 VA you will need a 6000 VA transformer. (6.0kVA)
The Transformer cannot change Frequency. In most cases this will not be a problem. This may occur with fans and motors.
If so you can calculate the watts (kVA) required:
Calculated as Watts (kVA)= Amps x Volts x 1.732 (eg 4 Amps x 200V x 1.732 = 1385 watts (or 1.4kVA)) For some Loads (non resistive) you will also need to take into account Power Factor (PF), or allow at least 25% Headroom. [ VA * PF = Watts ]
Most loads will be Inductive (motors and compressors) and have low pf around 0.8 or less)
Not sure which Unit you will need?
Then please contact us with your answers to above questions & we will advise the you the unit required.
For pricing, availability and further technical assistance, please contact our Sales engineers on: (02) 9642 6003, by email at: [email protected] or use our Design Form.
**Please note: If not in stock, a custom model must be manufactured with lead time of 1-4 weeks* and price may vary.
* Subject to change based on work in progress.

Prompt service and delivery. Transformer was used for a printing press operation and we were pleased that it was delivered so quickly as our client required installation within a week.
