Product Features (Bedook Solid State Relay SSR-DD)

BEDOOK’s Solid State Relay SSR – DD is a product that combines advanced technology with user-centric design. It is specifically tailored for DC applications, providing a more efficient and reliable alternative to traditional relays. The compact and durable design of the SSR-DD makes it easy to install in different electrical setups. The use of fire-proof ABS (UL94V0) as the housing material ensures safety and protection against fire risks. With its wide range of current and voltage capabilities, the SSR-DD can be integrated into a variety of systems, from simple DC circuits to complex industrial control systems. The brand’s reputation for innovation and quality assurance further enhances the appeal of the Bedook Solid State Relay SSR – DD in the global market.

Wide Range of Rated Currents: The Bedook Solid State Relay SSR – DD offers a diverse selection of rated currents, from 5A max in the SSR – 05DD to 70A max in the SSR – 70DD. This wide range allows customers to precisely match the relay to their specific load requirements. In comparison to some competitors with a more limited current range, the SSR-DD provides greater flexibility. For example, in a low-power electronic device, the SSR – 05DD can be used, while in a high-power industrial motor control system, the SSR – 70DD can handle the large current demands.

High Surge-withstanding Current: The SSR – DD models have impressive surge-withstanding current capabilities, ranging from 15A max in SSR – 05DD to 225A max in SSR – 70DD. This feature is crucial in applications where sudden current surges are common, such as when motors start or when there are electrical disturbances. The ability to handle these surges without damage ensures the long-term stability and reliability of the electrical system, giving it an edge over relays with lower surge-handling capacities.

Fast Response Time: All models of the SSR – DD have a response time of 1.0ms, which is extremely fast. In applications that require rapid switching, such as high-speed data processing circuits or in automated control systems where quick responses are essential, this fast response time can significantly improve the overall performance of the system. Many similar products may have slower response times, making the SSR – DD a more attractive option for time-sensitive applications.

Flexible Input and Output Voltage Ranges: The input voltage range of 4 – 32VDC and the output voltage ranges of 5 – 60V DC or 5 – 120V DC (depending on the model) provide flexibility in integrating the SSR – DD into different electrical systems. It can adapt to a variety of power supply conditions and load requirements. This versatility reduces the need for multiple types of relays for different voltage scenarios, saving both cost and space for the user compared to relays with more restricted voltage ranges.

Low Leakage Current: With a leakage current of only 1.0mA, the SSR – DD is highly efficient. Low leakage current means less power loss, which is beneficial for energy – saving applications. In comparison to some other relays that may have higher leakage currents, the SSR – DD helps to improve the overall energy efficiency of the electrical system, especially in applications where power consumption needs to be minimized.

Excellent Insulation and Dielectric Strength: The SSR – DD has an insulation strength of 100MΩ/500VDC and a dielectric strength of 4KVrms. These high-level insulation and dielectric properties ensure reliable electrical isolation between the input and output. This is crucial for safety, especially in high-voltage applications, and also helps to prevent electrical interference, making the SSR-D more reliable and stable than relays with lower insulation and dielectric capabilities.
