Product Features (Bedook Solid State Relay SSR-LA)

BEDOOK’s Solid State Relay SSR-LA stands out for its advanced features and robust construction. It is specifically engineered to provide efficient and stable electrical switching in AC-based systems. The SSR-LA series is not only about high performance but also about reliability. The use of fire-proof ABS (UL94V0) as the housing material ensures safety in case of any electrical malfunctions. With its wide range of current-handling capabilities and high surge-withstanding values, the SSR-LA can handle the rigors of demanding electrical applications. Whether it’s for controlling motors, heaters, or other electrical loads, the SSR-LA from BEDOOK offers a reliable and long-lasting solution.

1. Diverse Rated Current Options: The Bedook Solid State Relay SSR – LA offers three models with different rated current capabilities, from 10A max in SSR – 10LA to 40A max in SSR – 40LA. This allows customers to choose the most suitable relay according to their specific load requirements. In comparison to some single-rated – current competitors, the SSR-LA provides greater flexibility in application. For example, in a small-scale electrical device with a light load, the SSR – 10LA can be used, while for larger industrial equipment, the SSR – 40LA can handle the higher current demands.
2. High Surge – withstanding Capabilities: The SSR – LA models have significant surge-withstanding current values, ranging from 135A in SSR – 10LA to 410A in SSR – 40LA. This feature is crucial in electrical systems where sudden surges may occur due to motor starting, power grid fluctuations, or other reasons. The ability to withstand these surges without failure ensures the stability and longevity of the overall system, giving it an edge over relays with lower surge-withstanding capacities.
3. Precise Phase Control: The phase control mode of the SSR-LA is a unique and valuable feature. It enables more accurate control over the electrical output, which is beneficial in applications such as dimming lights, controlling the speed of AC motors, or regulating the power input to heaters. Many similar products may lack this precise control feature, making the SSR – LA a more attractive option for applications that require fine-tuning of electrical power.
4. Low Leakage Current: With a leakage current of at most 0.5% of the full load, the SSR – LA is highly efficient. Low leakage current means less power loss, which is not only energy – saving but also helps to maintain the stability of the electrical system. In comparison to some relays with higher leakage currents, the SSR – LA is more reliable and cost – effective in the long run.
5. Fast Response Time: The maximum response time of 1.0ms for all SSR – LA models ensures quick switching actions. In applications that require rapid response, such as in automated control systems or high – speed electrical circuits, this fast response time can significantly improve the overall performance of the system. It allows for more timely control and adjustment of electrical signals, setting it apart from slower – responding relays.
6. Excellent Insulation and Dielectric Strength: The SSR-LA has an insulation strength of 100MΩ/500VDC and a dielectric strength of 4KVrms. These high-level insulation and dielectric properties provide reliable electrical isolation between the input and output. This is essential for safety, especially in high-voltage applications, and also helps to prevent electrical interference, ensuring the stable operation of the relay and the connected electrical equipment.
