Scope of application:

Suitable for converting large currents into small currents,

Used for precision measurement or as electrical safety protection.

Precautions:

If the load connected to the secondary of the transformer exceeds the rated load capacity,

it may result in reduced accuracy or saturation. If you need to increase the load capacity and we can provide customized.
