    Maybe someone can help with a simple [??] problem.

    I recently acquired a Lambda WA305-00-00-03 switching supply, and
    am trying to get it to work at 120VAC. I downloaded the spec sheet,
    WA_FALL94.PDF, from the lambda website, but it really doesn't say
    much specific about hook-up. It's an obsolete supply, but purchased
    new from jameco.com.

    When powered up, I get the proper output voltage levels, but
    they drop off when I load the outputs. I don't see many jumper
    options, other than 2 pins that say "auto-ranging" near the
    AC input terminals. Ppossibly this comes set for ops at 220VAC
    and these need to be connected for operation at 120VAC? If so, how?


    thanks,
