Product Features (Bedook Solid State Relay SSR-D)

BEDOOK’s Solid State Relay SSR-D is designed with the latest in solid-state relay technology, it offers a more efficient and reliable alternative to traditional relays for DC loads. The SSR – D series is built to withstand harsh operating conditions, as evidenced by its vibration resistance (10 – 55 Hz, double amplitudes for 2 hours at X, Y, Z axis) and impact resistance (1000m/s², impact 3 times at X, Y, Z axis). Its compact design also makes it easy to integrate into various electrical systems, saving valuable space. With the BEDOOK brand’s reputation for excellence, the SSR-D is a product that you can rely on for long-term, trouble-free operation in your DC-based applications.

Diverse Current Ratings: The Bedook Solid State Relay SSR – D offers a wide range of rated load currents, from 10A in the SSR – 10D model to 70A in the SSR – 70D model. This diversity allows customers to select the most appropriate relay for their specific load requirements. For instance, in low-power DC circuits, the SSR-10D can be a perfect fit, while high-power industrial applications may benefit from the SSR-70D. This flexibility gives it an edge over some competitors that may have a more limited current – rating range.

High Peak Current Handling: With peak currents ranging from 160A to 520A (max 8.3ms operating time), the SSR – D can handle sudden surges in current. In applications where motors or other inductive loads are present, these peak currents can occur during startup or when there are changes in the load. The SSR-D’s ability to manage these transient events ensures the stability and longevity of the overall electrical system, which is a significant advantage compared to some similar products with lower peak-current capabilities.

Wide Load Voltage Range: The 24 – 380VAC load voltage range makes the SSR – D compatible with a broad spectrum of electrical systems. It can operate effectively in different voltage environments, whether it’s a low – voltage control circuit or a higher – voltage industrial setup. This wide range of adaptability reduces the need for multiple types of relays for different voltage applications, saving both cost and space for the user.

Fast Response Time: The response time of 1/2 Cycle + 1ms max (‘R’ type ≤1ms) is a key feature of the SSR – D. In applications that require rapid switching, such as in high-speed control systems or in circuits where precise timing is crucial, the fast response ensures that the relay can react promptly to control signals. This quick action can improve the overall efficiency and performance of the system, setting it apart from slower-responding relays in the market.

Excellent Insulation Properties: The SSR-D has an insulation resistance of 500VDC, 100MΩ (between input/output and housing) and a surge-withstanding voltage of 2500VAC (duration 1 minute at 60Hz). These insulation characteristics provide reliable isolation between the input and output, protecting the control circuit from the high-voltage load side. This is especially important in safety-critical applications and in environments where electrical interference may be present, giving it an advantage over relays with inferior insulation.

Durable Construction: Built to last, the SSR – D features a robust design that can withstand vibration (10 – 55 Hz, double amplitudes for 2 hours at X, Y, Z axis) and impact (1000m/s², impact 3 times at X, Y, Z axis). The housing is designed to protect the internal components from external mechanical stress, making it suitable for use in industrial environments where vibrations and impacts are common. This durability ensures a longer service life and reduces the need for frequent replacements, which is a significant cost-saving factor for users compared to less durable alternatives.
