Sensata Launches New Low Noise Solid State Relays

Sensata Technologies announced the availability of the new Low Noise (LN) series of panel mounted solid state relays designed for use in a wide range of consumer and industrial systems and products where precise power control, long life, reliability and reduced levels of electromagnetic noise are required.

Instead of using moving components as mechanical power relays do, solid state relays rely on silicon-controlled rectifier technology which allows SSRs to provide quieter operation (no clicking), longer life, as well as more precise switching control.

The new LN SSRs, from Sensata’s Crydom brand, conform with IEC 60947-4-3 Environment B and CISPR 11 standards for low voltage domestic, commercial and light industrial locations/installations and are compliant with C-UL-US and TUV certifications. The LN Series of panel mounted solid state relays offer reliable back-to-back SCR switching up to 75 Amps at 528 VAC. 

To comply with the low levels of electromagnetic noise required in many commercial and household applications, Sensata developed a patented trigger circuit design in the relay that prevents the need for external filters, thus reducing installation cost.
