Isolation transformer GE Transformers

Guard I & II Noise Isolation Transformer

Guard I
Guard I noise isolation transformers provide common mode noise attenuation and transverse mode noise attenuation.

Guard II
Guard II noise isolation transformers provide common mode noise attenuation plus an enhanced level of transverse mode noise attenuation for increased protection of sensitive electronic equipment.
