DESCRIPTION
The family of transformers P2820, P2821, P2822 and P2823 is specifically designed to provide signal coupling with safety for Powerline Carrier applications over four bands from 40kHz to 148.5kHz. Typically, the devices are driven from low- impedance sources and are connected to the mains network using capacitors whose values are chosen to resonate with the transformer leakage inductance. They are particularly suitable for use with tri-state power amplifiers, e.g. Texas Instruments TLE2301. The devices are completely lead-free, compliant with RoHS Directive 2002/95/EC, and suitable for lead-free and conventional processing. The devices are certified to IEC 60950 and UL 60950 for reinforced insulation. They are UL Recognized Components and are supported by an IEC CB Test Certificate. Furthermore, the devices are designed for low distortion and meet the requirements of EN 50065-1 for conducted emissions.
