(unequal length of load lines)
Option T: Current Sharing
This option ensures that the output currents are
approximately shared between all paralleled converters,
hence increasing system reliability. To use this facility,
simply interconnect the T pins of all converters and make
sure, that the reference pins for the T-pin (S- for the K1000
or V
o1
– for K2000) are also connected together. The load
lines should have equal length and cross section to ensure
equal voltage drops. Not more than 5 converters should be
connected in parallel. The R-pins should be left in an open-
circuit condition. If not, prior to paralleling the V
o1
outputs
should be individually adjusted within 1 to 2%. Parallel
connection of converters with option P
recommended.
is not
Option P: Potentiometer
The potentiometer allows for an output voltage adjustment
in the range of +10/–60% of
V
o nom
. It is accessible
through a hole in the front cover. This feature enables
compensation of voltage drops across the connector and
wiring. Option P is not recommended if models are
connected in parallel.
In double-output models both outputs are influenced by the
potentiometer setting. If option P is fitted, the R-pin 16 is
not connected.
Note:
If the output voltage is increased above
V
o nomvia the
R-input control, option P setting, remote sensing, or option T, the
output current(s) should be reduced accordingly so that
P
o nomis
not exceeded.
