AE Techron 8500 Series Switch-mode Amplifiers Introduction Congratulationsâonâyourâpurchaseâofâanâ8500âse-riesâdigitalâpowerâamplifier.â8500âseriesâamplifiersâareâ400Vp,âlow-noise,âDC-to-50-kHzâswitch-modeâamplifiers.âTheyâareâfastâenoughâforâDCâautomo-tiveâdropoutâtestingâandâcapableâofâACâvoltagesârequiredâforâISOâ61000âandâAviationâtesting.âPlus,âtheyâhaveâlowâenoughânoiseâandâdistortionâspecifi-cationsâtoâbeâtheâreferenceâpowerâsourceâinâpowerâquality measurements. Features Wide Bandwidth and Flexible Theâ8500âseriesâamplifierâisâcapableâofâreproduc-ingâAC,âDCâandâAC+DCâwaveformsâintoâloadsâfromâaâdeadâshortâtoâhighâimpedance.âItâcanâbeâusedâtoâsimulateâaâbatteryâatâ13.5âVDCâorâbeâanâACâsourceâwithâaâL-Nâpotentialâofâupâtoâ250âVAC.âRatedâcur-rent,âforâaâgivenâvoltage,âisâavailableâforâallâwave-formâtypesâ(AC,âDCâorâAC+DC)âatâfrequenciesâfromâDCâtoâ50âkHz.âVoltagesâfromâ0âtoâ250âVRMSâareâavailableâwithânoâchangesâinâconfiguration. Reuses Energy from Reactive Loads Theâ8500âseriesâexcelsâwhenâitâcomesâtoâdriv-ingâreactiveâloads.âAsâfrequenciesâincrease,âtheâeffective-impedanceâofâtheâloadâbecomesâaâmuchâlargerâpartâofâtheâtotalâloadâtoâbeâdrivenâ(especiallyâwithâinductiveâloadsâlikeâcoils). However,âwhenâdrivingâreactiveâloads,âtheâ8500âseriesâamplifierâisâcapableâofâreceiving,âreprocess-ingâandâreturningâtoâtheâloadâupâtoâ5Xâitsâratedâpower.âTheâresultâisâaâsystemâcapableâofâupâtoâ120 kVAâoutputâwhileâdrawingâlessâthanâ24âkWâofâACâmainsâpower! Configuration Options Aâkeyâtoâeverydayâproductâusabilityâisâquickâandâeasyâproductâ(re)configuration.âTheâ8500âseriesâamplifierâprovidesâallâkeyâconfigurationâcontrolsâonâtheâbackâpanelâofâtheâunit.âConfigurationâoptionsâavailableâinclude: Gain:âFixedâorâvariableâgainâ(0âtoâ40) Current Limit:âFromâ5%âtoâratedâlimitâ(to protectâfragileâDUTsâorâwhereâspecifiedâinâtheâŚ
