Lynbrook, NY [Apr 26, 2023] Signal Transformer, a Bel group company, announces the addition of the WRSR and WRSC series, which are designed to support wireless charging applications. Signal’s Circular Charging Coil (WRSC) and Rectangular Charging Coil (WRSR) Series are wireless charging coils available in a single winding configuration.
