CoolTech Series DIN rail solid-state relay is based on GN SSR technology and has a "true" 40 8C load-current rating. Other features include epoxy-free design and direct-bond copper (DBC) substrate. Design eliminates the stress placed on internal components from expanding and contracting epoxy. Vertically placed DBC substrate lets the SCR die transfer heat to the heat sink and into ambient air. Resulting lower temperatures reportedly allow for the true 40 8C load-current rating. Units are EMC (electromagnetic compatibility) compliant (level 3) for safe, reliable operation in harsh electrical environments. www.crouzet-usa.com Crouzet
