Product Overview
Signal's CL2 Series Class 2 Transformers are designed for printed circuit board mounting and are available in inherently or non-inherently limited versions. These transformers are UL 1585 / UL 5085 recognized and offer a power range from 2.5 VA to 50 VA. Featuring dual primaries (115/230 V, 50/60 Hz) and a single secondary, they are built with split bobbin construction for inherent electrostatic shielding. The insulation system is Class F (155 C), and the bobbin and shroud material carries a UL 94V0 flammability rating. These transformers are RoHS compliant.
