The new generation of high-performance solid state relays Crouzet, inventor of the ‘‘ready-to-use’’ solid state relay in the 1990’s, has further enhanced this concept using technological innovations to develop the new COOLTECH range of DIN Rail solid-state relays. "No heat sink calculations required!" Designed for superior thermal performance in harsh industrial environments, Crouzet's new CoolTech series is the most advanced DIN rail solid-state relay in its range on the market today. Based on GN SSR technology, the CoolTech solid-state relays have a combination of features not found in equivalent competitor's products. Epoxy-Free Design The epoxy-free design of the CoolTech SSR eliminates the stress placed on internal components due to the expansion and contraction of epoxy during normal use. Moreover, this eliminates the possibility of a catastrophic failure as a result of severe stress in the encapsulant during load failure.
