Precision transformer core-Iron core for anti-DC component transformer

views：854time：2020-05-08 18:47:57

Features

High initial permeability and high accuracy of transformer;

When the current has a DC component, it is not easy to saturate, ensuring the test accuracy of the transformer under certain DC conditions;

High and low temperature working performance is stable, and it can work for a long time at -55℃-130℃.
