Relays and temperature are intertwined. When a relay is exposed to various temperatures, its operating characteristics change dependent upon the temperature. The most notable changes occur in the pick-up voltage (V PI) and coil resistance (R C). The coil winding of a relay is produced with copper wire and thus the coil resistance varies with the temperature Over temperature protection in a power supply is a protection system that shuts down the power supply when the internal temperature exceeded a safe value.
