LD 200S19 - LOAD DUMP GENERATOR AS PER TOYOTA
Load Dump pulses simulate the sudden disconnection (e.g. by corrosion) of the battery from the alternator while the
alternator is generating current to load the battery. Such Load Dump pulses are high energy pulses with a high potential of
destruction.
The LD 200S19 generates the Load Dump pulses Test 1, Test 2 (Giant Pulse) and Test 3 as per Toyota specification.
