Application Characteristics

Suitable for functions such as power system relay protection and fault filtering, current, voltage, energy monitoring equipment, etc., ZM-BCT series, ZM-CT series, ZM-GCT series, ZM-RCT series, ZM-TCT series

Used for current detection, the product is small but its detection range is large (0-200A). The output is in the form of voltage, and it can be directly sampled. The linearity is better than 0.2%. The isolation withstand voltage between the primary and secondary windings is ≥3kV, which meets the requirements of four Level surge test.

Typical transformation ratio: 1.2A/3.53V 5A/0.46V 6A/3.53V 20A/3.53V 100A/7.07V
