Square D 118T44HDIT Drive Isolation Transformer
Manufacturer: Schneider

Drive Isolation transformers are not shielded isolation transformers, but act to lessen transient generation into the supply power and allow for high surge, harmonic and offset currents. They are designed for the requirements of both adjustable frequency and dc motor drive power isolation.

Features Model
  • Evaluated according to UL Standard 1561 for effects of harmonic heating
  • Designed for typical harmonics per IEEE 519-1992
  • Meets 4% minimum reactance for 150°C temperature rise designs
  • Conforms to IEEE-597 Class B overload, which requires 150% of load for one minute per hour
  • Designed for the mechanical stress of dc drive current spikes
  • Designed for the thermal and mechanical stress of highly cyclic process control applications
