Designed for superior thermal performance in harsh industrialenvironments, trodeks’s newSSRDIN/SSR3PH relay is the mostadvanced DIN rail solid state relay inits range. The epoxy-free designeliminates stress on internalcomponents, preventing damage tothe encapsulant during load failure.The vertical placement of the directbondsubstrate allows the SCR die toefficiently transfer heat to the heatsink and into ambient air. As a result,these relays can operate at a lowertemperature than their competitors,which accounts for the higher I2Tand surge-current ratings.

The SSRDIN’s internal transientprotection is fully repeatable, makingMOVs or other external suppressorsunnecessary. This feature allows theoutput to conduct load-current whena transient is detected across theoutput terminals, rather than forcingload-current through the protectioncircuit. Thus, no degradation ofprotection occurs.

These relays are ideal for numerouscommercial and industrial applications,including mercury relay replacement,professional food-service equipment(ovens, fryers, dispensing equipment,conveyors, etc.), sterilizers,temperature control systems, plasticextrusion/thermoforming machinery,HVAC and R, kilns, packagingequipment, sorting equipment, wavesolder and reflow systems, lightingsystems, pump controls, incubators,motor-switching, and UPS systems.
