Isolation transformers are very versatile and well suited for many commercial and industrial power supply and data communications applications, including: Low voltage (33 to 24 V) isolated DCDC power A reactor does not fix grounding issues nor does it provide isolation Keep in mind that while a reactor provides some buffering, it does not provide isolation and can not take the place of an isolation transformer If isolation is needed, an isolation transformer must be used Contact your distributor for an appropriately sized transformerLine Reactors and AC Drives Rockwell Automation
The required transformer size is determined by the volttime product of the application Therefore the first selection criterion for a gate drive transformer is the volttime product (Vµsec) rating as shown on the Electrical and Industrial Power management solutions EatonElectrical and Industrial Power management solutions
