Signal CL2 Series Transformer Bel Fuse CL2-5.0R-24 Dual Primary 115 230 Volt UL 94V0 Rated Material
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 feature dual primaries (115/230 V, 50/60 Hz) and a single secondary, with split bobbin construction eliminating the need for an electrostatic shield. The Class F insulation system (155 C) and UL 94V0 rated flammability material ensure safety and reliability.
