Product Overview:

The WCT100 and WCT1000 are high current wideband AC measuring transformers developed by ZES ZIMMER for precision power meters. They are designed for applications requiring wideband and high current performance, with a frequency range from 30Hz to 1MHz. These transformers fill a market gap by providing accurate high current sensors with high bandwidth and minimal phase shift.
