Indoor Low-Voltage Single-Phase Voltage Transformers (Potential Transformers)
S-N Series
Single-phase voltage transformers, or potential transformers, for indoor locations of lower humidity. Class-A insulation material. Used with measuring or monitoring instruments, or as an auxiliary power source in the main panel or motor control panel. In the latter usage, this product can be referred to as a "control power transformer" (CPT), "control transformer" (CTR), "industrial control transformer," or a "machine tool transformer."
PT as Auxiliary Power Source (Select Models)
About the Product
S-N Series low-voltage single-phase voltage transformers, or potential transformers, intended for usage in indoor locations of lower humidity, are insulated with a Class-A insulation material. These VTs (PTs) can be used in conjuction with measuring or monitoring instruments, or as an auxiliary power source in the main panel or motor control panel.
