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.

Max. Current

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.

Turns Ratio

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.

Accuracy Class

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.

Burden Resistance

The secondary wire connects a resistor which important to the accuracy.
