Sensata Technologies launches new low noise solid state relays

31 March 2020

Sensata Technologies, an industrial technology company and provider of sensors, has announced the Source: Sensata TechnologiesSource: Sensata Technologiesavailability of the new Low Noise (LN) series of panel mounted solid state relays (SSRs) 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, SSRs rely on silicon-controlled rectifier (SCR) 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 V AC.

Other critical features of the LN Series include:

• Zero voltage turn-on switching

• IP20 touch-safe housing available

• Built-in input/output over-voltage protection

• LED input status indicator

• 3500 V AC optical isolation

• EMC compliant to level III

• Available with standoffs for PCB mounting

To learn more about the LN Series of SSRs, check out the SSRs for Professional Food Equipment Application Note, or review the specification sheets.
