Product details
The 357-050-440-278 from EDAC Inc. sets new standards in Card Edge Connectors - Edgeboard Connectors for renewable energy systems. Engineered for photovoltaic applications, this connector delivers unmatched weather resistance and power handling capabilities.Compatible with Non Specified - Dual Edge configurations, the design features DC arc-quenching technology. When compared to standard connectors, it reduces arc flash energy by 95% during disconnect under load.The Female version includes touch-safe design. The insulated shroud prevents accidental contact with live parts up to 1500VDC.Featuring 25 contacts per bay, the layout optimizes current distribution. The parallel contact arrangement reduces thermal hot spots by 40% at full load.With 50 power contacts, the connector supports 30A continuous current. The silver-impregnated contacts maintain <0.2m resistance after 10,000 thermal cycles.Designed for 0.054" ~ 0.070" (1.37mm ~ 1.78mm) bus bars, the connector features spring-loaded compression contacts. This design maintains constant pressure despite thermal expansion of copper conductors.The 2 row configuration includes integrated surge protection. These metal-oxide varistors clamp transient voltages below 1.5kV for sensitive monitoring circuits.The 0.156" (3.96mm) pitch design prevents tracking in humid conditions. The creepage distance exceeds IEC 61730 Class II requirements for photovoltaic applications.Dual capability enables string monitoring. The isolated sense contacts provide 0.5% voltage measurement accuracy.The Card Guides package includes integrated combiner functionality. These built-in diodes prevent reverse current flow during partial shading conditions.Through Hole installation withstands wind loading up to 90mph. The reinforced mounting points distribute mechanical stress across the entire panel structure.The Wire Wrap process creates gas-tight connections. Ultrasonic welding produces joints with 100% cross-sectional conductivity.Copper Alloy contacts exhibit excellent corrosion resistance. Salt fog testing per UL 6703 shows no degradation after 3000 hours exposure.The Tin surface treatment prevents fretting corrosion. The micro-roughened surface retains lubricant through 500+ thermal cycles.The Semi Bellows design includes self-cleaning action. Each mating cycle produces 5mm of contact wipe to maintain oxide-free surfaces.The Black housing incorporates UV-reflective pigments. Accelerated weathering tests show <5% color shift after 10 years equivalent sun exposure.Flush Mount, Top Opening, Threaded Insert, 4-40 includes water diversion channels. These patented features prevent moisture accumulation at the cable entry point.Rated for -40°C ~ 105°C, the connector maintains flexibility from -40 C to 120 C. The material formulation resists embrittlement in extreme cold.
