Isolating and Safety Transformers

The Meth Transformers Group offer a wide range of isolating and safety transformers which are used to transfer electrical power from a source of alternating current to another device or equipment whilst isolating the powered device from the power source, offering substantial protection and acting as a safety transformer.

Meth Transformers Group offers and six different types of isolating and safety transformers, including T1, T1Q, T1ULF, T1UL, T1C and T1-IT.

 

T1, T1Q, T1ULF and T1UL

Low voltage single-phase isolating and safety transformers that are ENEC and UL-CSA marked. Isolating transformer with secondary voltage up to 50V and safety transformer with secondary voltage up to 50V. 

Suitable for any industrial/civil use for the electrical isolation of the input and output sides.
