Use Weschler CTs, PTs and shunts as the front end to a panel meter, transmitter, data logger or tester. AC Current Transformers are available in sizes from 1 to 200VA, currents to 5000A and windows up to 8". Split core models simplify installation on existing lines. Potential Transformers reduce high AC line voltages to a level compatible with most meters. DC Ammeter Shunts handle up to 10000A with an output of 50 or 100mV full scale. Other current, voltage, frequency & power transducers also available. (More) (CT Application Note)
