Electronic Standard Relay - ESR10 ISO Micro Description The smart power relay ESR10 Micro (Electronic Standard Relay) is a solid state relay which can replace electro-mechanical relays. The ESR10 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 10 A for max. 85° C / (12 and 24) Vdc l 17 A for max. 105° C / (12 and 24) Vdc l 30 A for max. 85° C / 12 Vdc Applications ESR10 Micro The ESR10 helps to switch loads whose current demand is too high to be connected directly to the controlgear. The switching function of the ESR10 is completely noiseless. This allows installation in the vehicle's interior. The ESR10 Micro is suitable for all applications in DC 12 V or 24 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 CO2 emissions. l The solid state relay switches silently and features wear-free operation of all loads with an extremely long life span.

In this case the trigger threshold should be adjusted. In the event of reverse polarity connection, the MOSFET will switch through automatically for self-protection. www.e-t-a.de 1 5 Electronic Standard Relay - ESR10 ISO Micro Technical data (25 °C) – ESR10 Micro 17 A Technical data (25 °C) – ESR10 Micro 30 A Voltage supply LINE+ System voltage Voltage supply LINE+ UB Operating voltage DC 12 V / DC 24 V System voltage 6...16 V / 10...32 V Operating voltage Closed current1) OFF 8 µA Load circuit LOAD Load output MOSFET, high side switching (HSS) Load typesresistive, inductive and capacitive Protective functionshort circuit proof, temperature disconnection (pulsing) Current rating IN 17 A Voltage drop1) UON 75 mV Max. short circuit current 100 A (L/R = 3 ms) Control input IN+ Control voltage ON 12 V: ±6...16 V; 24 V: ±10...32 V OFF 12 V: ±0...2 V; 24 V: ±0...4 V Control current 1) 2)10 mA (at 13.5 V respectively 27 V) (derating see chart) Switching frequency max. see chart Rising edge < 5 ms General data Reverse polarity load yes (reverse polarity conductive) 3) protection circuit, load circuit Cycle times 1) tON 0.5 ms tOFF 0.5 ms Temperature range -40 °C…105 °C DimensionsISO Standard Micro (with retaining lugs) plugged in 26 x 15.5 x 26 mm including contacts 26 x 15.5 x 37 mm Mass1) 15 g Approvals Authority Approval mark Regulation KBA E1 ECE R 10 UB DC 12 V 6...16 V Closed current1) OFF 5 µA Load circuit LOAD Load output MOSFET, high side switching (HSS) Load typesresistive, inductive and capacitive Protective functionshort circuit proof, temperature disconnection (pulsing) Current rating IN 30 A Voltage drop1) UON 50 mV Max. short circuit current 100 A (L/R = 3 ms) Control input IN+ Control voltage ON 12 V: ±6...16 V OFF 12 V: ±0...2 V Control current 1) 2)10 mA (at 13.5 V respectively 27 V) (derating see chart) Switching frequency max. see chart Rising edge < 5 ms General data Reverse polarity load yes (reverse polarity conductive) 3) protection circuit, load circuit Cycle times 1) tON 0.5 ms tOFF 3.5 ms Temperature range -40 °C…85 °C DimensionsISO Standard Micro (with retaining lugs) plugged in 26 x 15.5 x 26 mm including contacts 26 x 15.5 x 37 mm Mass1) 15 g Important: The 30A version of the ESR10 Micro will only be available upon request and for high volume projects (> 5000 pcs).
