D Undervoltage Monitor
The input and/or output undervoltage monitoring circuit op-
erates independently of the built-in input undervoltage lock-
out circuit. A logic "low" (JFET output) or "high" signal (NPN
output) s generated at pin 20 as soon as one of the moni-
tored voltages drops below the preselected threshold level
U
t
. The return for this signal is Vo1

when the monitored voltage(s) exceed(s) U

ed range is
basically possible but causes a special type designation in addition to the standard option designations (D0/D9)!

Option D monitors the boost regulator output voltage. The trigger level is adjusted in the factory to 355 V DC.
threshold level U

is adjusted in the factory. The threshold
level U

through a hole in the front cover, or factory adjusted to a
fi

ed by the customer.
Option D exists in various versions D0...DD as shown in the
