Littelfuse, Inc. (NASDAQ: LFUS), a leading industrial technology manufacturer focused on sustainability, connectivity, and safety, has introduced the SRP1 Solid-State Relays (SSRs) family. Designed to meet the growing demand for more reliable and durable switching components in industrial and commercial machinery, the SRP1 SSRs offer exceptional reliability, enhanced durability, and an extended operational lifespan, even in the most challenging environments.
Traditional relays often suffer from mechanical failures due to continuous use. Addressing this issue, Littelfuse developed the SRP1 SSRs to prioritize reliability and longevity. These solid-state relays eliminate the weaknesses associated with mechanical components, providing a more robust alternative that ensures consistent performance in demanding industrial and commercial settings.
At the core of the SRP1 SSRs is a proprietary, enhanced power component designed by Littelfuse to deliver optimal performance under strenuous conditions. This custom-engineered component resists heat degradation, significantly reducing the risk of failure, minimizing downtime, and improving overall productivity in machinery and applications.
The SRP1 SSRs are ideal for a wide range of markets and applications, including:
- Industrial Automation: Plastic machinery, packaging machinery, industrial ovens
- HVAC: Electric heating in air handling units, rooftop units, variable air units
- Food & Beverage: Cooking ovens, coffee machines, warming trays, warming displays
“With the launch of our new solid-state relay series, we are excited to offer our customers a solution that meets their needs for more robust and efficient systems,” said Hugo Neri, Global Product Manager of Industrial Solid-State Relays at Littelfuse. “This product minimizes operational disruptions and maintenance, giving our customers peace of mind across various applications, so they can focus on what they do best.”
Key benefits of the SRP1 Solid-State Relays include:
- High-Endurance Design: Provides enhanced operational reliability and extended service life of up to ~750K life stress cycles, ensuring consistent performance in demanding conditions. (Basic SRP1 relays offer up to ~350K life stress cycles.)
- Versatile Performance Range: Available with ratings from 10 A to 90 A at both low and high voltages, and with options for AC or DC control. The Zero Voltage & Instantaneous (Random) turn-on options provide precise control, enhancing efficiency and compatibility across applications.
- Integrated Protection & Installation Features: Incorporates IP20 finger-safe protection and overvoltage protection, making installation straightforward and secure.
- Compliance with International Standards: Undergoes rigorous testing to ensure enhanced safety and product quality.
The SRP1 SSRs are available in five configurations:
- SRP1-CR: All-in-one SSRs with touch-safe and overvoltage protection
- SRP1-CB: Basic SSRs offering design flexibility
- SRP1-CB…F: Quick-connect terminals for fast installation
- SRP1-CE: Basic SSRs for simple heating applications
- SRP1-CC: Ideal for DC voltage load applications
With the release of the SRP1 Solid-State Relays, Littelfuse reaffirms its commitment to solid-state technology solutions. The SRP1 SSRs expand the Littelfuse product portfolio, which also includes PCB-Mount Solid-State Relays, HVAC Solid-State Timers, and power components such as SCRs and MOSFETs. This comprehensive lineup underscores the company’s dedication to innovation and leadership, offering customers advanced solutions that set new industry standards.
