CLAMP ON ADAPTER 9290-10

AC Current Transformer to Meet Applications Exceeding 1000A AC

Hioki clamp sensors are best-in-class measuring devices incorporating
Hioki’s expertise in current sensing technology. The 9290-10 is
a clamp-on adapter rated for 1500A AC, and features a 10:1 CT ratio.
In addition to the large clamp diameter, broad frequency characteristics
and good phase characteristics, the CT reliably provides Hioki clamp on
power meters with expanded range and large current measurements.
