The trend towards more compact machines and control cabinets places increasingly high demands on the available installation space. With the SF548340, Celduc offers a solid-state relay (SSR) that occupies only approximately 301 TP3T of the volume of a conventional hockey-puck relay, without compromising on switching capacity.
The zero-cross SSR is suitable for switching AC loads from 12 to 280 VAC and can handle loads up to 30 A (AC-1). This makes the relay suitable for use in applications such as heating controls, packaging machines, and other industrial installations where frequent and maintenance-free switching is desired. For resistive loads, power ratings of up to approximately 4 kW are achievable.
Thanks to solid-state technology, switching takes place without mechanical contacts. This eliminates contact wear, extends service life, and prevents contact bounce. Furthermore, the integrated zero-cross circuit limits inrush currents and reduces mains pollution when switching AC loads.
The SF548340 features a wide control voltage range of 3 to 32 VDC, enabling direct control from PLC outputs. Furthermore, integrated surge protection (transil), an isolation voltage of 4000 Vrms, and international certifications ensure safe operation in industrial environments.
The main benefits:
- 70% space saving compared to conventional hockey puck relays
- High switching capacity: 30 A / 230 VAC
- Easy installation: FASTON terminals and LED status indication
- Equipped with CE, UKCA, UL, and VDE certifications
For machine builders looking for a compact power switching solution, the SF548340 combines high power density with the benefits of solid-state switching technology.
