MPG 200S20 - Automotive Micropulse Generator
Micropulses occur on the battery supply system when an inductive load is disconnected from the DC supply. These pulses are of a medium energy content having a rise time in the low microsecond range and a duration of several tenth or hundreds/thousands of microseconds. Their polarity depends on whether the inductive load is of a passive (e.g. a heater) or an active type (e.g. a DC motor).
The MPG 200S20 has a built-in battery switch to interrupt the DC supply voltage as required by the standards. It is designed to generate pulses 1b and 6 as per GOST standard 28751-90 as well as pulse 6 as per ISO 7637-1:1990.
