Peerless Electronics Stocking Specially Tuned Sensata Solar Arc Fault Detectors

Custom versions for specific applications are also available.

The Sensata PVAF family of solar arc fault detectors allows PV inverter and combiner box manufacturers to develop National Electric Code (NEC) 2011-compliant equipment. The PVAF family is a series of UL 1699B-recognized, pre-integrated arc detection solutions for use in inverters or combiner boxes on new arrays, or retrofit boxes on existing arrays.


Sensata's proprietary solution detects arcs while minimizing nuisance trips by identifying the electrical noise signature created by arc faults in the array wiring. Each PVAF device monitors up to four PV strings by itself, and multiple PVAFs can run in parallel to monitor more strings or a whole combiner box.

The PVAF series is available in configurations powered with 12 VDC or 24 VDC, and for monitoring strings up to 15 A at 1,000 V or combined lines up to 40 A at 1,000 V. Custom versions for specific applications are also available.

New for 2015 is the 20 amp version of the PVAF. The new PVAF-R4-20A24-002 is a Sensata Arc fault detector for solar applications. This version has stand-off mounting holes. Enables compliance with 2011 US National Electric Code (NEC 2011 Article 690.11). Up to 4 CTs / 4 strings per device. Each CT detects arcs on conductors up to 20A, 1000VDC (80A for entire device). Multiple devices can be nested for larger numbers of strings. This part ending -002 is specially tuned to maximize the margin of safety against nuisance tripping on arrays with central inverters. Applications in combiner boxes or string inverters. UL recognized. Stand-off mounting holes. These products are stocked at Sensata's authorized stocking distributor Peerless Electronics Inc.

Vecoplan - Planning and implementation of complete processing plants in refuse derived fuel production

In order to reduce the costs involved in the energy-intensive production of cement, many manufacturers are turning to refuse-derived fuels (RDF), considerably reducing the proportion of expensive primary fuels they would normally use. Solid fuels are being increasingly used - these might be used tyres, waste wood or mixtures of plastics, paper, composite materials and textiles. Vecoplan provides operators of cement plants with proven and robust components for conveying the material and separating iron and impurities, efficient receiving stations, storage systems and, of course, efficient shredders for an output in various qualities.
