Dry type Drive Isolation transformer is specially designed to meet the requirements of AC and DC variable speed drives and rectifier outputs. It is suitable for applications in commercial buildings and manufacturing facilities, can work under almost all ambient conditions. The transformer have primary and secondary that are physically separated from each other. Secondary neutral to ground bonding eliminates common mode noise, providing an isolated neutral-ground reference for sensitive equipment
