Product Description
Product Overview
Signals 14A Series International Transformers are designed for low power applications, providing the high isolation, creepage, and clearance required to meet international safety standards. These transformers offer dual primaries (115/230 V - 50/60 Hz) and dual secondaries that can be configured in series or parallel. They feature a Class F (155 C) insulation system and bobbin/shroud materials that meet UL 94-V0 flammability rating. The 14A series is suitable for applications demanding compliance with international standards at a lower cost with improved performance.
