Feature: 1. EMERGENCY POWER QUICK CONNECTOR: Our quick connector is a set of emergency power access devices that utilize the technology of spark free connection with existing electrical quick couplers and microcomputer industrial connectors. 2. FINE WORKMANSHIP: The housing is made of new PA material, which has a high melting point and excellent resistance to heat, oil, and aging. The terminal is made of 99.99% high purity copper, silver plated, ensuring strong conductivity and long term stable operation of output current. 3. CONSTANT CONTACT RESISTANCE: The connector series is made of specially formed elastic copper alloy strips, which are silver plated or gold plated according to their applications. With its constant spring pressure, the connector maintains continuous contact with the contact surface, resulting in low and constant contact resistance. 4. WIDE APPLICATIONS: The connector technology allows us to meet a wide range of requirements and find solutions for the most stringent limitations, including electrical (up to several kA), thermal (up to 350 ??), and mechanical, with contact durability of up to 1 million insertion and withdrawal cycles. 5. CONVENIENT IDENTIFICATION: The connector comes in four different colors for easy identification and prevention of errors. The main pole of the connector is equipped with a dust cover, effectively avoiding external factors affecting the power generation system in harsh environments. It is suitable for backup power devices, test benches, switchgear, construction machinery, as well as onshore and offshore applications in harsh conditions.
