Electronic Standard Relay - ESR ISO Micro Description The smart power relay ESR Micro (Electronic Standard Relay) is a solid state relay which can replace electro-mechanical relays. The ESR is a plus switching (high side switch) closing relay (NO) in an ISO Micro automotive relay enclosure. It allows bipolar control by a positive voltage. This space-saving relay is available in three power classes: l A for max. C / ( and ) Vdc l A for max. C / ( and ) Vdc l 0 A for max. C / Vdc Applications The ESR helps to switch loads whose current demand is too high to be connected directly to the controlgear. The switching function of the ESR is completely noiseless. This allows installation in the vehicle's interior. The ESR Micro is suitable for all applications in DC V or V electrical systems where valves, motors, lamps etc. have to switched: l Road vehicles (passenger cars, bicycles, trucks, buses, working vehicles and emergency cars, special vehicles) l Construction vehicles and agricultural vehicles l Watercraft (ships, sailing boats, motor yachts etc.) Benefits l The low current consumption, particularly in the ON condition, helps to reduce gas consumption as well as CO emissions. l The solid state relay switches silently and features wear-free operation of all loads with an extremely long life span.
