PRODUCT DATA SHEET P2827 POWERLINE CARRIER ISOLATION TRANSFORMER Features Applications ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ Powerline Carrier Lead-free (Pb-free) RoHS compliant Reinforced insulation 14.6mm seated height Vacuum encapsulated Low distortion IEC 60950 and UL 60950 certified UL Recognized Component Ratio 1.68:1 Differential surge resistance DESCRIPTION P2827 is specifically designed to provide signal coupling with safety for Powerline Carrier applications from 40 – 90kHz. The device is completely lead-free, compliant with RoHS Directive 2002/95/EC, and suitable for lead-free and conventional processing. Typically, the device is driven from a low-impedance source and connected to the mains network using capacitors whose values are chosen to resonate with the transformer leakage inductance. The device is certified to IEC 60950 and UL 60950 for reinforced insulation, is a UL Recognized Component and is supported by an IEC CB Test Certificate. Furthermore, the device is designed for low distortion and meets the requirements of EN 50065-1 for conducted emissions. P2827 is a drop-in replacement for P2820 where improved differential surge resistance is required.
