The EM Test PFS 200N Automotive Power Fail simulator is used to comply with standard requirements, mainly from vehicle manufacturers, to perform fast voltage dips ad drops (micro-interruptions). Some standards specify very fast rise and fall times below 1 microsecond an electronic switch.
The PFS 200N is a standalone tester providing an electronic switch to perform voltage dips and drops (micro-interruptions) with fast rise and fall times of 1 microsecond. For voltage dips two DC voltage supplies are required while for for voltage drops (micro-interruptions) only one DC voltage supply is needed. The PFS 200N has the ability to control one external DC voltage source by means of an analog DC signal.
The EM Test PFS 200N can also be easily integrated into a complete test set-up. Operation is possible both manually and by software via USB or GPIB. Fail inputs allow to control an ongoing test sequence based on the status of the DUT.
