LN Series

The Sensata Crydom LN Series Solid State Relays (SSRs) provide high performance, low noise switching solutions for AC loads, making them ideal for commercial, residential, and medical applications. With back-to-back SCR switching, the LN Series is designed to handle resistive loads up to 75A at 528 VAC, ensuring reliable operation even under heavy loads. The series incorporates Sensata Crydom’s patented low noise trigger circuit, significantly reducing electromagnetic interference (EMI) and ensuring compliance with IEC 60947-4-3 standards for low voltage environments. 

The LN Series is available in two operating voltage ranges: 24-280 VAC and 48-528 VAC, providing options for various applications. Each relay offers a zero-voltage turn-on switching, ensuring smooth operation and preventing power surges. The LN Series also features built-in input and output over-voltage protection, safeguarding sensitive equipment against voltage spikes. The SSRs are designed with an optional IP20 rated touch-safe housing, ensuring safety and easy installation in environments where direct contact protection is essential. 

For enhanced operational reliability, the LN Series offers 3500 VAC optical isolation and EMC compliance to level 3, providing robust performance in environments with electrical noise. The relays are also UL recognised and TUV certified, meeting international safety and quality standards. 

The LN Series Solid State Relays are perfect for demanding applications such as commercial ovens, professional cooking equipment, household appliances, and medical devices. Their low noise operation and high surge capacity make them a dependable solution for both light industrial and residential installations. With LED input status indicators, users can easily monitor the relay’s operational status, ensuring efficient and effective performance. 

For industries where noise reduction, reliability, and safety are critical, Sensata Crydom’s LN Series offers a superior, high-performance solution that meets the highest global standards.
