  • Embedded measurement system with 12 input channels and 100kSamp/sec waveform capture
  • emPower™ Test Executive
  • PC-LAN control


The S400 Series Functional Test Systems are modular test systems that are PC-controlled, full-capability and highly flexible modular power supply test systems suitable for high-speed testing of power supplies typically used in high volume consumer applications.

The key to the S400 system’s flexibility, as well as space-saving design, is the modular DC load/source mainframe. This is the portion where flexibility is most often required. What makes this subsystem unique is that the 6-slot chassis will accept any combination of DC electronic loads and/or DC source modules.

Additional flexibility is gained through the ability to synchronously parallel like modules from within a test program to match each supply-under-test’s specific stimulus requirements. In this manner, it is possible to configure a wide range of virtual loads and sources within the chassis’ limits. All modules also have wide operating ranges and constant power operating envelopes to maximize range of requirements through a minimum group of modules.
