D Undervoltage Monitor
The input and/or output undervoltage monitoring circuit
operates independently of the built-in input undervoltage
lockout circuit. A logic "low" (self conducting JFET) or "high"
signal (NPN output) is generated at the D output (pin 20),
when one of the monitored voltages drops below the
preselected threshold level V
S– / Vo1–. The D output recovers, when the monitored
voltages exceed V
in the factory. The threshold level V
potentiometer accessible through a hole in the front cover,
or adjusted in the factory to a fixed value specified by the
customer.
Option D exists in various versions D0 – DD, as shown in
the table below.
JFET output (D0 – D4):
Pin D is internally connected via the drain-source path of a
JFET (self-conducting type) to the negative potential of
output 1. V
voltage level (V
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.
