Managing Power Loads for High Voltage and High Amperage CONNECTOR COMPATIBILITY
High ampacity and high power loads place unique demands on connector dielectrics and design High altitude DWV is a critical requirement in non-pressurized and SWAMP zone aerospace applications. This innovative two-piece contact dielectric architecture, with Top Hat insulator design, lengthens discharge creep path in shorting and flashover testing. This unique capability is available in the Series 806 Mil-Aero—the only high- performance micro miniature circular capable of meeting MIL-DTL-38999 70,000 ft. DWV rating. 1 Increases in operating temperature often lead to decreased life and reliability in interconnect systems. Contacts and connectors have current ratings both at sea level and at increased altitudes that dictate how much current a conductor can safely tolerate—and its corresponding temperature rise. PowerLoad™ is a high-temperature resistant connector series designed for high-altitude aircraft power distribution applications with premium quality insulation materials and gap-free component bonding to ensure optimal operating temperature performance. Contact spacing within the dielectric insulator also dictates current and power load carrying capacity. Legacy power connectors such as the MIL- DTL-5015 typically relied on low-density contact- to-contact spacing to accommodate the otherwise poor-quality dielectric insulator. Modern power interconnects, such as the Super ITS™ - 921, utilize thermoplastic dielectric materials with significantly improved temperature tolerance—allowing for a higher-density connector design. 3 2
