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.
Note: This schematic diagram is the basic working principle of the transformer. We can design the transformer sampling circuit for the customer.
