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.

2 Fixed value tracking if Vo1 is adjusted via R-input, option P or sense lines.
3 The threshold level is permanently adjusted according to customer specification ±2% at 25 °C. Any value within the
specified range is possible, but causes a new customer-specific type designation.
