The PFS 200N Automotive Power Fail Simulator is used to comply with standard requirements, mainly from vehicle manufacturers, to perform fast voltage dips and drops (micro-interruptions). Some standards specify very fast rise and fall times below 1 microsecond and an electronic switch. While for drop-outs (from nominal voltage value to 0 V) only one DC source is needed, for voltage dips (reduction of voltage level to other levels than 0 V) two DC voltage supplies are reuqired. The output voltage of the second supply (PF2) can be controlled via the 0-10 V analogue output at the PFS 200Nx unit. As a second DC supply we recommend the RDS 200N1 unit. Operation of the generator is possible both, manually from the front panel as well as by the remote software iso.control. In standard mode the remote software tool offers a large variety of preprogrammed testing. In device mode you have a similar ability to modify the parameters as by operating from the front panel. The PFS 200N units can also be easily integraded into a complete test setup with more EM Test automotive transient generators.
