Product details
The K31S50A by Altech Corporation redefines Power Entry Connectors - Inlets, Outlets, Modules performance for renewable energy systems. Designed specifically for solar inverters, this connector handles {Current - IEC} continuous current with ultra-low contact resistance, ensuring maximum power transfer efficiency in photovoltaic applications.Featuring Pin and Sleeve (2P3W) architecture, this connector incorporates sunlight-resistant polymer housing. The UV-stabilized material maintains mechanical integrity after 10,000 hours of outdoor exposure.Engineered as Receptacle, Female Sockets, this solution utilizes silver-plated copper alloy contacts. The multi-point contact design ensures <0.5m resistance even after thermal cycling.Rated for 16A at 70 C ambient, the connector exceeds IEC 60947-1 derating requirements. The thermal mass design prevents hot spots during current surges.UL-listed for 20A makes this connector ideal for microinverter arrays. The parallel contact design distributes current evenly across multiple paths.UL-recognized for 480VAC applications, this connector meets NEC 690 solar equipment requirements. The flame-retardant housing achieves V-0 rating without halogen additives.The Unfiltered - Commercial configuration provides 50dB common-mode rejection from 150kHz-30MHz. The balanced LC network maintains neutral-ground isolation above 1M .No design includes IP65-rated fuse compartment. The quick-change mechanism allows maintenance without specialized tools.With 3 isolated circuits, the connector supports three-phase inverter outputs. Each pole maintains 8mm creepage distance.The Free Hanging (In-Line) system includes corrosion-resistant stainless steel hardware. The compression gasket accommodates panel warpage up to 1.5mm.Featuring Screw technology, the connector accepts 4-300mm conductors. The torque-limiting screws prevent over-compression of fine-strand cables.The Chemical Resistant, Cord Grip, Cover, Impact Resistant, Push-Twist Lock, Strain Relief package includes integrated DC arc detection. The self-cleaning contacts maintain performance in dusty environments.The UL94 V-2 compound achieves UL94 5VA performance. The material retains mechanical properties at 125 C continuous.IP44 rating ensures reliable operation in desert environments. The multi-labyrinth seal design excludes fine sand particles.Certified by cULus for photovoltaic applications. The complete type testing includes 1000 thermal cycles from -40 C to +85 C.
