Product introductionThe ¸TS-PSM1 is a power switchingmodule controlled by a CAN-businterface. Its innovative technology andversatile functionality provide excellentsuitability for automotive and high-currentswitching applications, e.g. powermanagementand test-load paradigms.The special design of the moduleensures ideal routing of supply and loadpaths through the test system. High-currentforce channels and sense channelsfrom voltage or current sources can beswitched and routed to the DUTs via themodule. In the opposite direction, singlepoleor multipole loads can be appliedto the DUTs. High-power multiplexers onthe module provide selectability of differentload simulations that may be integratedin the ¸TSVP (Test SystemVersatile Platform) base units.The currents and voltages can be measuredor monitored at all switchingnodes by means of additional relays onthe module and the Rohde & Schwarzanalog bus. Shunt resistors are integratedfor measuring high currents.This characteristic is particularly importantif the power consumption of theDUT must be measured during normaloperation and in standby modes. Additionally,the tests of various operatingmodes and their current consumptioncan be executed without interruptingthe DUT’s powerpath.The Power Switching Module¸TS PSM1 can be used in the¸CompactTSVP and in the¸PowerTSVP. It is a CAN-buscontrolledmodule which takes up onlyone slot.Flexible signal routingThe design of the switching module andthe wide voltage and current rangesensure high flexibility and a wide applicationrange.Even complex yet flexible load systemswith original or electronic loads canbe configured to obtain a high- current¸PowerTSVP switching instrumentby means of device-internal connectionof the multiplexed power channels.When lower power signals are measured,the signal concept relies on the systemwideanalog bus.The appropriate way of handling analogsignals led to the interconnection solutionof the ¸TSVP analog bus. The analogbus is located immediately above thefront connector area where space is providedfor on-board signal conditioningand signal routing by coupling relays forthe analog bus. This distance to the digitalsignals on the backplane significantlyimproves signal quality.Additionally, the dedicated switchingmodules such as the ¸TS-PSM1 arecontrolled via the low-noise and interference-resistantCAN bus, which ensuresoverall high reliability and signal quality,especially in the vicinity of high-currentsignals.2 Power Switching Module ¸TS-PSM1

Direct current measurement via the analogmeasurement bus is limited to 1 A, butmeasurements up to 16 A can be performedby forwarding the shunt resistorvoltages of the ¸TS-PSM1 viathe analog bus to a precise multimetersuch as the ¸TS-PSAM in the¸CompactTSVP.Typical applications◆ Switching of voltage or currentsources to DUTs◆ Switching of DUT loads as originalloads or simulated/electronic loads◆ Power multiplexer for DUT signals totest devices◆ Analog functional test for generalpurposesignals◆ Switch simulation for DUTsSoft front panel for the ¸TS-PSM1Software supportSecurity by selftest anddiagnostic featuresA LabWindows/CVI driver accordingto the IVI standard is available for theswitching functions of the module.Function panels and online help areavailable as common features for theLabWindows/CVI driver.¸TS-PSM1The built-in selftest capability of themodule ranges from fast diagnosticsto the complete, automated evaluationof all relays and switching paths(¸TS-PSAM required).
