IDT arc fault detector helps protect solar installations from fire hazards

By Kathie Zipp Integrated Device Technology (IDT) introduced a single-chip photovoltaic DC arc fault detector to help protect against fire hazards in solar power systems. The ZNRG2061 is a system-on-chip (SoC) built around the IDT ArcWizard trainable algorithm, which ensures reliable signaling of arc faults while avoiding nuisance tripping. The ZNRG2061 is designed for implementation in PV solar power inverters, combiner boxes, DC optimizers and arc fault circuit interrupters (AFCIs).
The ZNRG2061 works in 12V and 24V power supply installations. It requires few external components and comes in a small footprint 5 x 5 mm QFN package. The device is a UL Recognized
