CRYDOM - solid state relays from specialists

Silent operation, immunity against mechanical shocks and magnetic field and other factors make a solid state relay the best choice for many applications.

This is an archive article published 03/12/2015. Some information may no longer be up to date and in line with the current state. Please contact us in case of interest.

Where to start? We´ll try to name “pluses” of solid state relays - SSR:

● long lifetime, no moving parts, no contact burning
● silent operation, very desirable for commercial and medical applications
● minimum electrical noise thanks to a possibility of zero-crossing switching
● easy control (interfacing) and minimum energy consumption to control
● resistance to shocks and vibrations, installation in any position
● fast switching (approx. 0.1 ms)
● low weight
● immunity to outer magnetic field (usable near powerful motors,…)

Some disadvantage of SSR is, that they generate more heat when conducting a current through "contacts", than classic EMR. But this is dependent on a switched current. On the other hand - power consumption of the SSR itself is minimal in comparison to EMR of a similar size.

From above mentioned features result, that SSRs are a great choice everywhere, where it´s necessary to switch frequently and/or also to change rotation of motors (integrated in a single component). SSRs are also maximally suitable for switching of DC currents (solar applications, batteries,...) as they don´t suffer by arcing and contact wearing like classic EMRs (DC arcing is much more difficult to extinguish than the AC one). Much longer lifetime in comparison to EMRs result in very low operation/ service costs and significantly eliminates losses caused by eventual downtimes.

If we allured you to SSR, than it´s certainly worth to take a look at products of a leading producer in this field - výrobky spoločnosti CRYDOM, which specializes for development and production of SSRs already for over 40 years. Among novelties in our stock can be found Crydom SSR for PCB in SIP and miniSIP packages, panel mount types, as well as types for a DIN-rail mount. Their basic features are very similar, they differ mainly in max. voltage and current, which they´re able to switch.

Practically each SSR Crydom is available for switching of AC or DC current and also in an “R” version (random switching in any phase of AC voltage) or „ZCD - zero crossing“ switching in "zero" (suitable for minimizing of switching noise).

Detailed specification can be found in the datasheets at jednotlivých typoch and a help at selecting will provide you documents Crydom overview, Crydom product guide, Crydom Selecting SSR and Crydom motion control. The „SSR-the inside story" document is intended for those of you, who like to understand components deeply.

In case of interest in any Crydom products (also non-stock ones), please contact us at info@soselectronic.com.
