Model EMA - Electronic Power Supply Protection System Datasheet

Electronic power supply protection EMA Devices that are connected tovehicles electronic chain can be damagedby over-voltage which can appear invehicles power supply system. Electronicpower supply protection EMA matches ISO7637-2 standard. It protects electronicdevices from over-voltage and incorrectconnection. Technical dataParameter, measuring unit Value Operating voltage, V 10,0 - 26,0Operating current, A 0,001 - 2,0Protection from possitive over-voltageI. 1kV duration < 1msII. 600V duration < 300msIII. < 80V outup voltage stabilizedIV. < 50V duration < 300ms in the output voltage are stabilezed to 28VIf I and II voltage will be exceeded 2A inputfuse blows and device will not workProtection from negative over-voltageI. 1kV duration < 1msII. 600V duration < 300msIII. Device will be turned off if there is negative voltageIV. If I and II voltage will be exceeded 2A input resistor will burn and device will not workProtection from incorrect connectionIf connection is incorrect, poles are switched: EMA will disable power supply toconnected device if power are < (-30V) if not input fuse blow
