    T Current Sharing
    This option ensures that the output currents are approxi-
    mately shared between all paralleled modules hence in-
    creasing system reliability. To use this facility, simply inter-
    connect the T pins of all modules and make sure, that pins
    14, the S– pins (K 1000) or the Vo1– pins (K 2000) are also
    connected together. The load leads should have equal
    length and cross section to ensure equal voltage drops. Not
    more than 5 units should be connected in parallel. If output
    voltage adjustment is requested we strongly recommend to
    use the R-input instead of option P, as with option P the re-
    quired setting accuracy is difficult to achieve. The output
    voltages must be individually set prior to paralleling to
    within a tolerance of 1...2% or the R pins should be con-
    nected together.
