The wide range of input resistances and the variable-resistor input voltage design make the SSR-VA adaptable to different power-supply scenarios. Whether it’s for controlling motors, lighting systems, or other AC-powered equipment, the Bedook Solid State Relay SSR – VA is engineered to meet the challenges of modern electrical applications with ease.

• Variable Rated Currents for Diverse Applications:The Bedook Solid State Relay SSR – VA comes in three models with different rated current capabilities, from 10A max in SSR – 10VA to 40A max in SSR – 40VA. This variety allows customers to select the most appropriate relay according to the load requirements of their electrical systems. In contrast to some competitors that offer only a limited range of current ratings, the SSR-VA provides greater flexibility. For instance, in a small-scale electrical device such as a household appliance, the SSR – 10VA can be a perfect fit, while for larger industrial machinery, the SSR – 40VA can handle the higher current demands, ensuring optimal performance and efficiency.
• High Surge-withstanding Capacity:The SSR – VA models exhibit impressive surge-withstanding current values, ranging from 135A in SSR – 10VA to 410A in SSR – 40VA, along with a minimum surge-withstanding voltage of 1200VAC. This feature is crucial in electrical systems where sudden voltage and current surges are common, such as during power-grid fluctuations, motor starting, or lightning strikes. The ability to withstand these surges without failure safeguards the relay and the connected equipment, enhancing the overall reliability and longevity of the electrical system. Compared to many similar products with lower surge-withstanding capabilities, the SSR-VA offers superior protection and stability.
• Precise Phasecontrol Function:The phase-control mode of the SSR-VA is a key differentiator. It enables users to have precise control over the electrical output, which is highly beneficial in applications such as speed regulation of AC motors, dimming of lighting systems, and power control of heating elements. By adjusting the phase of the electrical signal, the SSR-VA can achieve smooth and accurate power regulation, optimizing the performance of the connected devices. Many competing relays lack this level of precision in control, making the SSR-VA a preferred choice for applications that demand fine-tuning of electrical power.
• Wide Input – voltage Adaptability:The SSR – VA features a variable-resistor input voltage design with different input resistances (250KΩ/110VAC, 500KΩ/220VAC, 1MΩ/380VAC) and a minimum VR power of 1/4 W. This design allows the relay to adapt to a wide range of input – voltage sources, providing flexibility in system integration. It can be easily incorporated into various electrical setups with different power-supply specifications, reducing the need for additional voltage-conversion components. This adaptability gives the SSR-VA an edge over relays with more restricted input-voltage requirements, making it a versatile option for different electrical applications.
• Fast Response Time:All models of the SSR-VA have a maximum response time of 1.0ms, ensuring rapid switching actions. In modern electrical systems, especially those with automated control and high-speed operation requirements, a fast response time is essential. Whether it’s for quick-acting protective circuits or high-frequency switching applications, the SSR-VA can respond promptly to control signals, enabling seamless operation and improved system performance. This fast-response characteristic sets it apart from slower-responding relays in the market.
• Excellent Insulation and Dielectric Strength:The SSR-VA has an insulation strength of 100MΩ/500VDC and a dielectric strength of 4 KVrms. These high-quality insulation and dielectric properties ensure reliable electrical isolation between the input and output, protecting the control circuit from high-voltage surges and electrical interference. This is of utmost importance in terms of safety, especially in high-voltage applications, and also contributes to the stable operation of the relay and the entire electrical system. Compared to relays with lower insulation and dielectric strength, the SSR-VA offers enhanced protection and reliability.
