Autoranging Offers Users Maximum Flexibility

To allow users to test multiple voltage and current combinations with a single source, EA Elektro-Automatik programmable DC power supplies offer true autoranging. The source automatically provides increased current at lower voltages, allowing users to test more devices with just one supply.

    00:00:00 [Music] programmable dc sources are used in virtually every product development lab and production test environment and electronic devices are often tested under various power supply conditions for example a 3 kilowatt device under test or dut operates from a dc supply that is nominally 380 volts

    00:00:22 but can vary from 180 to 420 volts testing this requires providing 16.7 amps at 180 volts and 7.1 amps at 420 volts and possibly intermediate voltage in current combinations this is problematic with conventional power supplies that have a square power profile as the rated power is only delivered at the maximum voltage and

    00:00:42 current a typical 5 kilowatt supply rated for 500 volts and 10 amps addresses the voltage range of our 3 kilowatt duty but it can't supply the current needed at 180 volts despite having a much higher power rating than the dut this can be addressed using different supplies for each test condition or by oversizing to an even larger power

    00:01:02 supply such as a 10 kilowatt supply rated for 500 volts and 20 amps but both options increase equipment cost and rack or bench space alternatively engineers can use an auto ranging power supply auto ranging power supplies have a more dynamic power profile scaling current up as voltage drops and vice versa

    00:01:20 and while many auto ranging power supplies start to lose power before dropping to even 50 percent of their rated output voltage electro automatic's true auto ranging capability provides full power down to 33 of the rated output voltage driving our three kilowatt duty can be easily done with a 5 kilowatt 500 volt psi 9000 series supply

    00:01:39 as it can supply up to 30 amps or engineers can opt for the 5 kilowatt 750 volt psi 9000 series supply that can output up to 20 amps meeting current test requirements while providing additional voltage to address future testing requirements both options offer more flexibility while saving money and rack space simply put auto ranging allows you to
