The easy-to-use, IEC EN61000-4-2-compliant unit makes discharging EUTs safe and efficient, while comprehensively fulfilling many automotive, household and industry test standard requirements, including ISO 10605.
Teseq’s new ESD simulator offers flexible control parameters for both the built-in and external EUT discharging circuit. It features three freely programmable time parameters that allow the charge holding time to be precisely defined.
The operator can simply set the discharge cycle time and the associated repetition intervals of the ESD pulses so that any residual voltage is guaranteed to be removed from the EUT. The sum of all three time segments equals the pulse repetition rate, an adjustable rate ranging from 0.1 seconds to 99 seconds in intervals of 0.1 seconds.
By setting the relay closing or opening time with the ESD simulator’s touch panel, users can monitor all three independent EUT discharge time segments. The segments are defined into three categories – T1, T2 and T3.
During T1, the ESD pulse energy is maintained or bleeds off from the EUT within the context of an ordinary discharge event. The discharge relay closes in order to remove the residual charge once the preselected time expires.
T2 defines how long the complete discharge phase should last, determined by the environment, the EUT’s design and the test procedure being performed. The simulator’s tip is connected to ground via a 1MΩ resistor.
Segment T3 is when the discharge path relay opens. This period may be used to verify EUT’s function. Once the time has been completed, the cycle begins again.
