Current Transformer with Lead Wire

The current transformer with lead wire provides a high-quality solution, at low cost for current sensing. The wire gauge, wire length, and wire connector can be specified by customers. The long lead wires provide the benefit of a high accuracy remote monitor for many applications. The current transformer is constructed by a high permeability nanocrystalline core, or a composite core, which make DC immune possible. We provide different kinds of encapsulations, such as plastic case, metal shielding, insulation tape wrapped current transformer. If lead wires are not required in the applications, we can provide PCB mount current transformers, which can be easliy mounted in the devices or instruments.
