LV covers tests for electric and electronic components for use in motor vehicles up to 3,5 t with a 12 V electric mOhm. Tolerances & standard values. LV Automotive test standard bij Hielkema Testequipment. The LV includes several mechanical, climatic and life tests, such as the K damp heat. ISO , Road vehicles—Environmental conditions and electrical testing for electrical and electronic equipment, is an ISO standard which provides guidance .

The test serves to verify functioning of the component when subjected to shock-type cooling by means of water.

A component must always undergo both sequences. Makro function With a comfortable macro editor and its execution, selected waveforms run sequentially. Previous issues VW In principle, this temperature distribution is a continuous distribution, as the ambient temperature of the component may adopt any value between Tmin and Tmax. The represented tests do not serve for component qualification or a qualification of the manufacturing process. The easy-to-use WaveMaster software, that is standard in scope of delivery, allows to generate waveforms by means of a graphical user interface or via tabular input.
The behavior goes from DC to voltage changes within max. We also want to distinguish the modular design that allows to build up systems with up to 18 kW.
VW is one of the most important standards of the automotive industry.
Functional status A 4. Also an internal trigger is available to start both the waveforms and an additional measurement unit. With an optional isolation amplifier, the instruments have two analogue inputs. All E-tests can be executed fully automated, individually or completely and in any desired order.
Voltage- and current control
Schematic circuit for test E Backfeeds 4. During reverse polarity, the permissible limit values specified in the data sheet electrical and thermal must not be exceeded for any of the parts. Intermitting 55 standars operating mode II.
The test room temperature is controlled by means of the temperature-controlled water bath. The maximum test voltage results from commercial vehicle systems and their increased power supply voltage.
Assuming standxrd the component maintains the temperature after 20 min, we have a holding time of 35 min. Tests; Test Eb and Guidance: Test boundary conditions e.
LV/ LV Tests – INSYS test
A deviating value for the permissibility of functional status C must be defined in the Component Performance Specifications. If the manufacturing process of the electr. Short test 3x test pulse within 10 s 2.
The total test duration tGes is the sum of top, max and tmax. Shandard functions that must retain their performance when the engine is not running For functions that must retain their performance when the engine is running c d 9V 16 V 9,8 V 16 Lvv124 Test voltages, especially for over- and undervoltage tests may deviate significantly from the voltage ranges mentioned above and will be specified individually. The SIB series are linear precision 4-quadrant power amplifiers for fast voltage and current signals – each positive and negative bipolar.
The reverse polarity must not cause pre-damage or hidden damage on the component.
The sampling rate must be selected so that interruptions or short circuits can be unambiguously detected. Higher currents than in the normal load case e. The selected type of application must be documented in the test report. The climate control is switched off during the condensation phase. Sequence of the condensation test, 1 cycle 1. Analog lv214 input The test serves to verify the resistance of the part to faults, such as component displacement or material fatigue. A graphical waveform editor allows to generate individual curves in a flash.
It must be verified that the DUT has not been damaged. Sstandard components are activated directly before starting for a short period, then deactivated during starting and activated again atandard starting when the engine is running.
LV-124/ LV-148 tests with the eTS one
Electrical loads pv124 ISO The device under test DUT must comply with the requirements for nonflammability acc. Verification takes place by means of continuous parameter monitoring and a parameter test small acc. Each connector must be removed once.
