Application:

CTS Split-Core Current Transformer – This series are used where it is desirable for the current transformer to be installed without disconnecting the primary conductor. The CTS products offers exceptionally accurate signal transformation with low phase shift while exposed to harsh environmental operating conditions. The emphasis on product quality results in consistent product performance from CT to CT with very low failure rates over the very large production volumes of the CTS family of products.

Features:

• Incorporates high performance electromagnetic cores; Nickel Alloy and Silicon Steel available.
• Characterized by high sensitivity, accuracy, linearity.
