Product Description
Product Overview
Signals PC/DPC Series Miniature Low Power Transformers are engineered for reliable operation within a frequency range of 50 Hz to 500 Hz, maintaining consistent output voltage without degradation. These transformers are designed for printed circuit board mounting and offer a versatile 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 recognition, they are suitable for various industrial applications requiring compact and robust power conversion solutions.
