  • Notes

  • The Lambda LL-902 is one of the LL Series of regulated power supplies with an IC as the adjustment element. Features include: coarse and fine voltage adjustment; current adjustment; and a switch for measuring voltage or current on the analog meter.

    Initially, the models had an adjustable overvoltage (OV) protection option for the LL-901 ($20), LL-902 ($20), and LL-903 ($25).  The LL-905 did not have an  OV option.  Some models may have been marked "-OV" or "-V" to indicate that the OV option was installed.

    Later production runs added the OV option as standard in all 3 models, and sold all 4 models for $99.

    One export version was "-W" (France).

    The LL Series included:

    Model DC Voltage Range (V) DC Current Range (A)
    LL-901 0 - 10 0 - 1.000
    LL-902 0 - 20 0 - 0.650
    LL-903 0 - 40 0 - 0.350
    LL-905 0 - 120 0 - 0.065
