Three Phase European Step Down Transformer

Clear

Note: If you require custom made three phase transformers please see here.

3 Phase European 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 380VAC.

These European, Chinese or Korean Three Phase Step Down Transformers are rated in either 10kVA and 40kVA, and are an ideal solution if you want to run an Overseas device rated at 380VAC in Australia. They also can be used for multiple purposes including Industrial and Commercial machines/appliances.

For American or Japanese Three Phase machines/appliances that require a 200VAC or 220VAC output transformer, 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).

To help determine which Transformer you will need, please check these questions first:

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.
