Overview
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).
EM Test MPG 200 Description:
The EM Test 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.
EM Test MPG 200 Benefits:
The EM Test MPG 200S20 includes everything necessary to conduct fully compliant tests. The built-in electronic battery switch enables interruption of the DC supply voltage as required by the standards. The MPG 200S20 is a standalone tester including a 60V/25A DC coupling/decoupling network but still it can be integrated easily into a complete test system.
Operation is both manual and by software via GPIB or RS232. Fail inputs allow to control an ongoing test sequence based on the status of the DUT. A warning lamp control contact and a safety interlock is provided.
Pre-programmed Standard Test routines allow highest user convenience. Still the MPG 200S20 offers the Quick Start test routine where parameters can be changed on-line during the test to evaluate the susceptibility level of an individual DUT.
