OPEN OR ENCLOSED CUSTOM BUILT

SINGLE & THREE PHASE AUTO TRANSFORMERS

Custom built single phase auto transformers

Either open or enclosed types

Non safety isolating

Insulation classes E or F

Ideal where the output voltage is similar to the input voltage

and where safety isolation is not required

With accessories, including plugs and sockets, wheels, cooling

fans, indicator lamps, meters and mains isolator switches.

1ph auto

A comprehensive range of custom built single phase auto transformers in either open or enclosed types.

Major reductions in both size and cost can be achieved using auto transformers. They should only be used in applications

where an isolated output is not a safety requirement. Auto transformers are single winding units and offer no isolation between

input and output circuits. They are frequently used to adjust voltages for exported or imported machines or equipment.

Our sales department will calculate the size and cost reductions where auto transformers can be utilised.

Auto transformer types available

Custom built three phase auto transformers

Either open or enclosed types

Non safety isolating

Insulation classes E or F

Ideal where output voltage (s) are similar to input voltage (s)

and where safety isolation is not required

With accessories including, plugs and sockets, wheels, cooling

fans, indicator lamps, meters and mains isolator switches.

3ph auto

A comprehensive range of custom built three phase auto transformers in either open or enclosed types.
