    Input voltage monitoring
    Output voltage monitoring
    Threshold tolerances and hysteresis:
    If
    Ui is monitored, the internal input voltage is measured af-
    ter the input filter and rectifier (LK types). Consequently this
    voltage differs from the voltage at the connector pins by the
    voltage drop
    Uti across input filter and rectifier. The
    threshold level of option V0 is adjusted during manufacture
    at
    Io nom and TA = 25 °C. The value of U ti depends upon the
    input voltage range (AK, BK, ...), threshold level
    U t, tem-
    perature and input current. The input current is a function of
    input voltage and output power.
    Option B1 Cooling Plate (see "Mechanical Data")
    Where a cooling surface is available, we recommend the
    use of a cooling plate (option B1) instead of the standard
    heatsink. The mounting system should ensure sufficient
    cooling capacity to guarantee that the maximum case tem-
