The Celduc SDI series is an advanced solid-state relay based on IGBT technology, designed for reliably switching DC voltages up to 100A at 750Vdc. These relays are ideal for applications such as railway systems and industrial heating elements, where precise control and high reliability are crucial.
The SDI series excels in safety, flexibility, and performance. Versions are available for 50 A and 100 A, with a wide range of control voltages from 24–110 VDC.
The relays are designed for extreme industrial conditions and have a range of integrated protections:
- Diagnostic and status outputs for instant feedback and faster troubleshooting
- Overvoltage and transient protection for longer life
- Overload, short-circuit and overheating protection for maximum safety
- Continuous current monitoring (with 50 A version) for proactive fault detection
Compared to electromechanical relays, Celduc SDI relays offer advantages such as lower maintenance, better heat dissipation and higher system reliability.
