K-BUS power supply for K-Series modules

General Description

The K-SUPPLY module permits the delivery of power supply to numerous K-Series
modules through K-BUS connection by creating interface between an external power
supply system and the user module distribution bus. The impossibility of tapping
current from the bus to the input terminals permits the connection of numerous K-
SUPPLY modules in parallel on the same bus together with the protection provided
against polarity inversion permits the module to offer valid protection against
erroneous connections.
Main features:
two independent inputs that permit the use of one power supply system; redundant
power supply that guarantees the presence of power supply even whenever the
source of either input undergoes power failure;
indication of the presence of each channel: the LED switches on only when there is
sufficient voltage for the operation of the K-Series modules connected;
a LED that signals input inverted polarity or alternating current;
built-in over-voltage (surge) protection;
differential mode filter.

2, with shared negative terminal.
Pass-through: each input can be accessed by two
pairs of terminals, in this way permitting the same
power supply source to be used for more than one
K-Supply module (see the section entitled Example
of Connection to more than one bus).
19,2..30 Vdc
Maximum current per terminal: 4 A
Each positive input must be provided with protection
by an external fuse (see the section entitled Fuse
Sizing Selection).
The device has no limit on maximum current.
