Control Power Transformers / LV Potential Transformers

CPT Series

Used as potential transformers or control power transformers (CPT's), these resin-cast (Class-A insulation) products are both economical and versatile.

About the Product

Suitable for use in machine tools or industrial equipment as a control transformer, this product is often referred to as an "industrial control transformer," "machine tool transformer," or "control power transformer (CPT)."

This versatile product can also be installed in low-voltage control panels as an auxiliary power source or as a potential transformer (voltage transformer) for measuring.

This low-voltage, single-phase potential transformer or control transformer is resin-cast for Class-A insulation. It is compact, economical, and easy to install.
