Product Overview
Signal's CL2 Series Class 2 Transformers are designed for printed circuit board mounting, offering both inherently and non-inherently limited options. These transformers are UL 1585 / UL 5085 recognized and feature a split bobbin construction for effective insulation without the need for an electrostatic shield. They are suitable for a wide range of power requirements from 2.5 VA to 50 VA, with dual primaries (115/230 V, 50/60 Hz) and single secondaries. The insulation system is Class F (155 C) and the bobbin and shroud material is rated UL 94V0 for flammability. These transformers are RoHS Compliant.
