Option 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) is generated at pin 5 as soon as one of the moni-
tored voltages drops below the preselected threshold level
Ut. The return for this signal is Vo1– (pin 23). The D output
recovers when the monitored voltage(s) exceed(s)
Ut+Uh.
JFET output (D0…D4):
Connector pin D is internally connected via the drain-
source path of a JFET (self-conducting type) to the nega-
tive potential of output 1.
UD
≤ 0.4 V (logic low) corresponds
to a monitored voltage level (
Ui and/or Uo1) < Ut. The cur-
rent
ID through the JFET should not exceed 2.5 mA. The
JFET is protected by a 0.5 W Zener diode of 8.2 V against
external overvoltages.

NPN output (D5...D9):
Connector pin D is internally connected via the collector-
emitter path of a NPN transistor to the negative potential of
output 1.
UD < 0.4 V (logic low) corresponds to a monitored
voltage level (
Ui and/or Uo1) > Ut + Uh. The current ID
through the open collector should not exceed 20 mA. The
NPN output is not protected against external overvoltages.
UD should not exceed 40 V.

The threshold level
Ut is either adjustable by a potentio-
meter, accessible through a hole in the front cover, or is fac-
tory adjusted to a fixed value specified by the customer.
Option D exists in various versions D0...D9 as shown in the
following table.
