In the fast-evolving landscape of industrial automation and smart technology, solid state relays (SSRs) serve as the backbone of reliable electrical control. As a dedicated solid state relay manufacturer, Bedook has built a reputation for delivering innovative, high-performance solutions that meet the diverse needs of global customers. By focusing on technical excellence, rigorous quality control, user-centric design, and responsive service, Bedook has emerged as a preferred partner for businesses seeking dependable SSR solutions.

Unmatched Performance: Engineered for Diverse Applications
Gone are the days of worrying about mechanical wear and tear. Bedook SSRs feature a fully solid-state design, leveraging advanced semiconductor components like thyristors and MOSFETs to enable seamless circuit switching. This contactless architecture eliminates common issues of traditional relays, such as contact erosion, arc interference, and mechanical failure. Take our
SSR-A series, for example. With no moving parts, it offers a lifespan of over 100,000 switching operations, making it an ideal choice for high-frequency applications like automated conveyor systems and precision medical devices.
We understand that different loads demand different solutions. That’s why Bedook SSRs are designed to handle a wide range of load types with ease:
- Resistive Loads (e.g., heaters): The SSR-A series excels here, thanks to its low conduction voltage drop (≤1.6V) and zero-cross triggering technology. This not only ensures energy-efficient operation but also minimizes harmonic distortion, keeping your systems running smoothly.
- Inductive Loads (e.g., motors): Our SSR-DD series is built to withstand the challenges of inductive loads. Equipped with surge protection, it can handle instantaneous current spikes up to 10 times the rated current, safeguarding against damage from back EMF during motor startup and shutdown.
- Capacitive Loads (e.g., energy storage devices): The SSR-VA series uses phase-control technology to gently manage inrush currents, ensuring safe and stable operation of capacitive loads in applications like renewable energy systems.
In today’s fast-paced industrial environments, quick response and precise control are non-negotiable. Bedook SSRs deliver with response times as low as 1ms (e.g.,
SSR – LA series), making them perfect for integrating with PLC systems. Whether you need to adjust the speed of a motor or maintain tight temperature control in a manufacturing process, our SSRs ensure seamless communication with your control systems, enhancing overall efficiency.

As a forward-thinking solid state relay manufacturer, Bedook invests heavily in research and development. Our dedicated R&D team works tirelessly to improve key technologies such as high-temperature resistance and interference immunity. For instance, our SSRs feature optical isolation with a withstand voltage of 2500VAC, effectively blocking electromagnetic interference and ensuring stable performance in harsh industrial environments, from noisy factories to high-altitude installations.
Quality is at the heart of everything we do. Every Bedook SSR undergoes a series of strict tests to meet international standards:
- High-Temperature Aging Test: Products are subjected to 85℃ for 48 hours to ensure reliability in extreme heat.
- Voltage Withstand Test: A 1500VAC voltage is applied for 1 minute to verify insulation integrity.
- Load Cycle Test: Each SSR is tested for 100,000 switching cycles to ensure long-lasting performance. Well below the industry average, and certifications like UL, CE, and RoHS, ensuring compliance in markets around the world.
We know that time is money in industrial settings. That’s why Bedook SSRs are designed with modularity in mind. With standardized interfaces that support both DIN rail mounting and PCB soldering, and compatibility with leading control systems (such as Siemens and Mitsubishi PLCs), integrating our SSRs into your existing setups is a breeze. The
SSR-LA series, with its 4 – 20mA input, can connect directly to PLC analog output modules, saving you time and effort on additional circuit design.

We’ve simplified the installation process to help you get up and running quickly. Bedook SSRs come with clear wiring labels and anti-reverse connection protection, reducing the risk of installation errors. Many models also feature status indicators that show power, operation, and fault conditions at a glance, enabling fast troubleshooting and minimizing downtime.
No matter where your applications are located, Bedook SSRs are ready to perform. They operate reliably in a wide temperature range of – 40℃ to 85℃ and can handle humidity levels up to 95% RH. For example, the SSR-D series uses a sealed design to enhance moisture resistance, making it a top choice for coastal factories or food processing plants with high-humidity environments.
Heat is the enemy of electronic components, but Bedook has you covered. Our 大功率 (high – power) SSR models, such as those with 40A and above ratings, feature aluminum heat dissipation bases and low – thermal – resistance materials. This efficient thermal design keeps the junction temperature within a safe range (≤125℃), preventing performance degradation and extending the service life of your equipment.

At Bedook, we pride ourselves on our customer service. Our technical support team is available 24/7 to assist with any questions or issues. Whether you need help with 选型 (model selection) or troubleshooting, we’re here to provide prompt solutions, ensuring minimal disruption to your operations.
We understand that one size doesn’t fit all. With over 15 years of industry experience, our team is well-equipped to develop custom SSR solutions for your specific requirements. For example, we worked with a customer in the renewable energy sector to create a high – temperature – resistant SSR that could handle the harsh conditions of their solar panel control systems, resulting in improved reliability and efficiency.
We stand behind the quality of our products. All Bedook SSRs come with a warranty longer than the industry standard. This demonstrates our confidence in their durability and gives you peace of mind.
When compared to leading brands in the market, Bedook offers a compelling combination of performance, quality, and value. Our SSRs deliver comparable, and in many cases superior, technical specifications at a more competitive price point. We also support small-batch orders, making us an ideal choice for both large enterprises and small businesses. Our focus on understanding and meeting the unique needs of our customers sets us apart, allowing us to build long-lasting partnerships based on trust and mutual success.
