2. Features

Special double core structure. One core is for AC measurement, the other is for DC.
AC measurement capacity is 20-30% bigger than listed range.
DC measurement capacity is more than 71% of the listed AC measurement range.
High accuracy, AC measurement accuracy up to class 0.5 or class 1.0.
Typical meter measurement error after giving DC influence is at 0.5%-2% for 0.1class CT.
Small phase error, typical phase shift is at 1-10’; Additional compensation not needed
Good isolation between Primary and Secondary
Very reliable and stable performance at different temperature conditions
Frequency: 50Hz/60Hz Ambient Temperature: -40℃ -- 70℃

3. Size and Dimensions

Bus-bar shape and fixing dimension could be specially designed according to customer's meter box.
Dimension A, B, C, D, E, F, G could be changed according special requirement, too.
