How to Order Custom Mini Current Transformer
In order to make a customized current transformer, some important parameters should be specified by the clients in advance.
The measurement range of a mini current transformer is specified by its max. current. Within the range, the secondary current is proportional to the primary current.
For mini current transformer, typical turns ratios are 1:1000, 1:2000, 1:2500, 1:5000, etc. More turns means more higher accuracyr, but the manufacturing cost is also higher.
Most of our current transformers are 0.1 accuracy class. But higher accuracy, 0.05 class or 0.02 class are also available, while the price is higher. In some circumstances, lower accuracy class, such as 0.2 class or 0.5 class is suitable.
The secondary wire connects a resistor which important to the accuracy.
