Control Power Transformers / Low-Voltage (LV) Voltage Transformers (Potential Transformers)
CPT Series
These low-voltage control transformers, resin-insulated for Class A or Class F insulation, are economical while conforming to UL safety requirements and regulations. Highly resistant to moisture, heat and dust, these control power transformers are suitable for use at highly polluted locations. Some models of this versatile series can be used as voltage transformers (potential transformers) with Class 0.5 or Class 1.0 accuracy according to IEC’s standard for voltage transformers.
Low-Voltage Dry-Type Control Transformers
S Series
These low-voltage control power transformers, with Class A or Class H insulation, are economical products suitable for use with machine tools or industrial equipment at indoor locations with lower humidity. Also referred to as "control transformers" (CTR), "industrial control transformers," or "machine tool transformers," these control power transformers (CPT) can also be installed in low-voltage main panels or motor control panels as an auxiliary power source. This dry-type transformer is compact and easy to install.
