Interference suppressing isolating transformer
SMTT 150
Characteristics
General data
The isolating transformers of the SMTT series ensure safe galvanic isolation of the primary circuit from the secondary circuit and minimize mains interference. The transformers feature low leakage current, high insulation resistance, and good attenuation properties against high-frequency interference and impulses. The series offers a very high protection class.
Benefits
