For many years, the main device for controlling power was to use a contactor. This has gradually changed, and there has been wide acceptance of the use of solid state devices, whether they are solid state relays or power controllers.

Since its introduction, the SSR technology has gained acceptance in many areas that had previously been the sole domain of the EMR or the Contractor. The major growth areas have come from Industrial Process Control applications; particularly heat/cool temperature control, motors, lamps, solenoids, valves and transformers. The list of applications for the SSR is almost limitless.

The following are typical examples of SSR applications: industrial automation, electronic appliances, industrial appliances, packaging machines, tooling machines, manufacturing equipment, food equipment, security systems, industrial lighting, fire and security systems, dispensing machines, production equipment, on-board power control, traffic control, instrumentation systems, vending machines, test systems, office machines, medical equipment, display lighting, elevator control, metrology equipment, and entertainment lighting.

Pyrosales offers both standard SSRs that can be attached to a heatsink, or a range of slimline SSRs that have an integral heatsink, and can be din-rail mounted where space is an issue.

Advantages of using SSRs

When used correctly in the intended application, the SSR provides many of the characteristics that are often difficult to find in the EMR: a high degree of reliability, long service life, significantly reduced electromagnetic interference, fast response, and high vibration resistance are significant benefits of the SSR. The SSR has no moving parts to wear out or arcing contacts to deteriorate, which are often the primary cause of failure with an EMR.

  • Long life (reliability) > 109 operations
  • Zero voltage turn on, low EMI / RFI
  • Shock and vibration resistant
  • Random turn-on, proportional control
  • No contact bounce
  • Arcless switching
  • No acoustical noise
  • Microprocessor compatible
  • Fast response
  • No moving parts
