Product Description
Product Overview
Signals PC/DPC Series Miniature Low Power Transformers are engineered for reliable operation within the 50 Hz to 500 Hz frequency range without output voltage degradation. These transformers are designed for printed circuit board mounting and offer a range of power ratings from 1.0 VA to 24 VA. They feature single or dual primaries (115 V or 115/230 V) and dual secondaries configurable for series or parallel connections. With a Class B insulation system (130 C) and UL recognized and CSA certified compliance, these transformers are suitable for various industrial applications requiring stable low-power signal conditioning.
