Option V operates independently of the built-in input under-
voltage lockout circuit. A logic "low" signal is generated at pin 5
as soon as one of the monitored voltages drops below the pre-
selected threshold level V
(pin 23). The V output recovers, when the monitored voltage

Connector pin V is internally connected to the open collector of
a NPN transistor. The emitter is connected to the negative
potential of output 1. V
monitored voltage level (V
through the open collector should not exceed 50 mA. The NPN
output is not protected against external overvoltages. V
should not exceed 80 V.

Notes: The threshold level V
the factory to a value according to the table below. A decoupling
diode should be connected in series with the input of AM, BM, CM,
DM, and FM converters to avoid the input capacitance discharging
through other loads connected to the same source voltage. If LM
models are powered by AC, an external input capacitor cannot be
applied unless an additional rectifier is provided.
