Littelfuse Launches Industrial Solid-State Relays with Market Leading Reliability and Efficiency
Littelfuse, Inc. (NASDAQ: LFUS), an industrial technology manufacturing company empowering a sustainable, connected, and safer world, today announced the release of the SRP1 Solid-State Relays (SSRs) family. Engineered to address end-user demand for more reliable and durable switching components in industrial and commercial machinery applications, the SRP1 SSRs offer unparalleled reliability, enhanced durability, and prolonged operational lifespan even in the most challenging environments.
Conventional relays have long been plagued by mechanical failures under constant and prolonged use. Recognizing this critical issue, Littelfuse developed the SRP1 SSRs, focusing on reliability and longevity. These solid-state relays eliminate the vulnerabilities associated with mechanical components, offering a robust alternative that ensures consistent performance in demanding industrial and commercial settings.
At the heart of the SRP1 SSRs lies a proprietary, enhanced power component designed by Littelfuse. This tailor-made component is engineered to deliver optimal performance even under strenuous conditions, ensuring enhanced reliability and a longer lifespan for the relay. By resisting heat degradation, the power component significantly reduces the likelihood of failure, minimizing downtime and improving overall productivity in machinery and applications.
Typical markets and applications for the SRP1 include:
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 addresses their needs for more robust and efficient systems,” said Hugo Neri, Global Product Manager of Industrial Solid-State Relays at Littelfuse. “This product is set to minimize operational disruptions and maintenance, providing peace of mind in various applications, ensuring that our customers can focus on what they do best.”
The SRP1 Solid-State Relays incorporate these key benefits:
High-Endurance Design: Provides enhanced operational reliability and extended service life, up to ~750K life stress cycles, ensuring consistent performance even in demanding conditions. (Up to ~350K life stress cycles for basic SRP1 relays.)
Versatile Performance Range: With ratings from 10 A to 90 A at low or high voltage and the flexibility of AC or DC control, the SRP1 series caters to a wide array of power requirements. The Zero Voltage & Instantaneous (Random) turn-on options ensure precise control for various applications, enhancing efficiency and compatibility.
Integrated Protection & Installation Features: Incorporates IP20 finger-safe protection and overvoltage protection, facilitating straightforward and secure installation.
Compliance with International Standards: Ensures that the Solid-State Relay (SSR) has undergone rigorous testing, providing 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 for application 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 SRP1 Solid-State Relays launch, Littelfuse reinforces its commitment to solid-state technology solutions. The SRP1 SSRs join the existing Littelfuse portfolio, which includes PCB-Mount Solid-State Relays, HVAC Solid-State Timers, and power components such as SCRs and MOSFETs. This comprehensive product lineup showcases the company's dedication to innovation and leadership, providing customers with cutting-edge solutions that redefine industry standards.
Availability
The SRP1 Solid-State Relays are available in individual boxes. Sample requests can be placed through authorized Littelfuse distributors worldwide.
