Product Overview
Signal's CL2 Series Class 2 Transformers are designed for printed circuit and chassis mount applications. Available in inherently or non-inherently limited versions, these transformers are UL 1585 / UL 5085 recognized and RoHS compliant. They offer a power range from 2.5 VA to 50 VA, featuring dual primaries (115/230 V, 50/60 Hz) and a single secondary. The split bobbin construction eliminates the need for an electrostatic shield, and the Class F insulation system (155 C) provides reliable performance. Bobbin and shroud materials are rated UL 94V0 for flammability.
