The SRP1 SSRs offer exceptional reliability, enhanced durability, and a longer operational lifespan, even in the harshest environments.
Traditional relays often suffer from mechanical failures when subjected to constant and prolonged use. Addressing this critical issue, Littelfuse has developed the SRP1 SSRs with a focus on reliability and longevity. These solid-state relays eliminate the weaknesses associated with mechanical components, providing a robust alternative that ensures consistent performance in demanding industrial and commercial settings.
Central to the SRP1 SSRs is a proprietary, enhanced power component designed by Littelfuse. This component is engineered to deliver optimal performance under strenuous conditions, ensuring superior reliability and an extended lifespan for the relay. By resisting heat degradation, the power component significantly reduces the likelihood of failure, minimising downtime and enhancing 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 minimise 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 offer the following key benefits:
- High-endurance design: Enhanced operational reliability and extended service life, up to approximately 750K life stress cycles, ensuring consistent performance even in demanding conditions (up to approximately 350K life stress cycles for basic SRP1 relays)
- Versatile performance range: Ratings from 10 A to 90 A at low or high voltage, with the flexibility of AC or DC control. The Zero Voltage & Instantaneous (Random) turn-on options ensure precise control for various applications, enhancing efficiency and compatibility
- Integrated protection and installation features: IP20 finger-safe protection and overvoltage protection, facilitating straightforward and secure installation
- Compliance with international standards: Rigorous testing ensures enhanced safety and product quality
With the launch of the SRP1 Solid-State Relays, Littelfuse reinforces its commitment to solid-state technology solutions. The SRP1 SSRs complement the existing Littelfuse portfolio, which includes PCB-mount solid-state relays, HVAC solid-state timers, and power components such as SCRs and MOSFETs.
