Solid state relays with low electromagnetic noise emission: SON-series

celduc® relais has just launched last December a new range of EMC optimized Solid State Relays (with low electromagnetic emission – low RFI) : « SON » range. These relays are particularly suitable for applications where electromagnetic noise must be limited, such as:


  • Household and electrical appliances
  • Information technology
  • Medical equipment


You can find standard « low noise » SSR on the market but those are limited to low switching current of 5A for domestic applications or to low inductive loads, while lots of pure resistive loads applications have high emission noise.

Our new EMC optimized SON range meets these requirements (Conducted emission noise level < 66dBµV) and can control class B appliances on pure resistive loads.

Specifications SON865040 low noise solid state relay:


  • Control voltage range: 6 – 32 VDC
  • Max switching voltage: 40 – 275 VAC
  • Max switching current: 50 A
  • EMC optimised – low RFI – EN50081-1
  • Dimensions (B x H x D): 45 x 30 x 59 mm
  • Temperature range: -40 tot +100 °C
