      Option D: Undervoltage Monitor
      The input and/or output undervoltage monitoring circuit operates
      independently of the built-in input undervoltage lockout circuit. A
      logic "low" (JFET output) or "high" signal (NPN output) is
      generated at pin 20 as soon as one of the monitored voltages
      drops below the preselected threshold level Vt. The return for
      this signal is Vo1–. The D output recovers when the monitored
      voltage(s) exceed(s) Vt + Vh. The threshold levels Vti and Vto
      are either adjustable by a potentiometer, accessible through a hole
      in the front cover, or factory adjusted to a fixed value specified by
      the customer.
      Option D exists in various versions D0 - DD as shown in the
      following table.

      specified range is possible, but causes a new customer-specific type designation.
