Solve High In-Rush Current Challenges with the RK 9260 SSR from DOLD!

15-11-2024

DOLD is excited to introduce the RK 9260 solid-state relay (SSR), an advanced addition to its renowned POWERSWITCH series. Designed to monitor and switch short but high in-rush currents up to 165A for 20ms at 230V AC, the RK 9260 addresses a common issue in systems such as LED lighting controls, where high current peaks can occur at start-up. By incorporating the RK 9260 into system designs, engineers can ensure smooth operation of LED lamps and similar equipment, reducing stress on components and minimising the risks of relay failure and system downtime.

Beyond in-rush current management, the RK 9260 is engineered for frequent, wear-free, and silent switching of resistive loads, making it an ideal choice for heating, cooling, and lighting applications. Equipped with zero-crossing switching technology, it minimises electrical noise and provides superior performance in high-frequency applications like plastic injection moulding machines, thermoforming, soldering lines, and packaging machines. This combination of reliability, durability, and precise control makes the RK 9260 the engineer’s choice for robust system design in demanding environments.

Another key feature that improves performance is its use of Direct-Copper-Bonding (DCB) Technology. This method bonds a copper heat sink directly to the ceramic substrate, efficiently dissipating the heat generated by switching high currents within the relay. As a result, operational temperatures are kept lower, extending the life of the relay.

With a compact design measuring an impressive 17.5 mm in width, the RK 9260 is not only space-efficient but also highly resistant to vibrations and shocks. It supports a load current of up to 5A and promises an extended lifespan due to its high switching frequency and robust build. Additionally, the RK 9260 is ready for immediate use, thanks to its user-friendly, plug-and-play design, ensuring quick and easy integration into various systems.
