The LEMSYS DMS equipment has been modularly designed to enable it to measure different parameters with a single rack.
The main frame is made to be controlled by a Windows computer (PC) connected via the RS 232 serial bus. User-friendly software with automatic module detection enables flexibility and simplicity for setting the test conditions, performing test and storing results.
A set of plug-in modules is available to achieve the measurement of most dynamic switching parameters of the diodes.
Special modules are made on request according to customer's specifications.
The DMS is especially useful for component qualification, characterization and can also be used as a maintenance unit or in production.
