The very fast cycle time and electronic switching performed by AM Series Solid State Relays can significantly extend the life of electric heaters. Thermal expansion and contraction of the element is reduced because temperatures are typically more stable about the set point. This phenomenon is "Metal Fatigue" and is generally the "wearing out" process of electric heaters. In all applications using any type of relay device, a high limit control and contactor is recommended for protection. Proper heat sink is required as indicated. AM Series Solid State Relays are also available for switching 3 phase loads up to 55 amps. A built-in LED indicates power to the load.
