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 and beverage: Cooking ovens, coffee machines, warming trays, warming displays
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 and installation features: Incorporates IP20 finger-safe protection and overvoltage protection, facilitating straightforward and secure installation.
- Compliance with international standards: Ensures that the 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
