An isolation transformer is a transformer used to transfer electrical power from a source of alternating current (AC) power to some equipment or device while isolating the powered device from the power source, usually for safety reasons. Isolation transformers provide galvanic isolation and are used to protect against electric shock, to suppress electrical noise in sensitive devices, or to transfer power between two circuits which must not be connected. A transformer sold for isolation is often built with special insulation between primary and secondary, and is specified to withstand a high voltage between windings.

  • Ultra Isolation Transformer prevent back feeding of noise from line to load and protects sensitive loads from surges and spikes.
  • The potential between ground and neutral of the output side of UIT is zero.
  • Good Earthing of output Neutral is essential for proper functioning of the UIT.
