    Describe 

    National standard gb 1208-2006;

    Industry Standard jbt 10665-2006.

    Use Temperature:-25℃-+85℃

    Relative humidity:≤95%

    Scope of application:

    Suitable for instrumentation, etc., need to convert large current into

    small current for precise measurement, Used for precision measurement or as electrical safety protection.


    Notes:

    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.
