We sell a wide range of transformers, from a simple power tool transformer starting at just 1.0KVA to the most popular 3.3KVA power tool transformer, right up to larger site transformers of 10KVA.
Transformers take the power supply from one voltage to another, in most cases, this is taking it from a 230v (UK domestic mains) to a 110v power supply, unusually used on building sites for safety reasons. The different sizes of transformer are required for different powered applications. You should choose your transformers size based on the output you require (usually 16 amp or 32 amp sockets) and the KVA you will require from the items you will be running with it. Larger transformers will usually have more sockets to run multiple items.
Power Tool Transformers
The most popular size power tool transformer is 3.3KVA, as it will cover most requirements for 110v power tools, drills, saws, etc. The most popular sized generator is also around 3KVA output. Small power tool transformers are available around 1KVA, but these will usually only have one socket and are only an advantage as far as weight is concerned.
The most popular site transformers are 5KVA and 10KVA. These are available in single phase (230v) and three phase (415v). These transformers will usually have multiple plugs and will be connected to larger generators on site to run multiple tools and equipment.
These work in reverse, to the usual for the UK, they will step the voltage from a 110v input you may find from a site generator to a 230v three pin output, meaning you can run tools with a 230v plug from a site power supply, although we recommend checking with the site first.
We sell Electrowind and Defender transformers, they are bother highly regarded in the industry and have been sold for many years.
