Four-wire sense connections for battery and charger channels
Basic Power Supply Operation 2-3
Remote sense
As shown inFigure 2-1 the 2306 battery and charger channels are intended to be operated with
remote sense leads (4 wire connection). The Sense+ and Sense- pins
provide output voltage
sensing. Without these terminals connected, the power supply operates without voltage feedback
and therefore supplies an unregulated voltage. This unregulated voltage value can be up to +18V
or down to -5V. Use voltage protection to turn off the output and protect against the extremes
(refer to “Setting voltage protection value” on page 2-5).
Connect the sense inputs to the supply as close as possible to the load’
s source inputs through
twisted pair leads (refer to Figure 2-1). This is necessary to achieve the maximum transient per-
formance of the supply.
NOTE Do NO
T jumper the sense inputs and supply outputs at the rear of the supply! Con-
necting the sense leads in this fashion will severely compromise the performance of
Model 2306 with dynamic
loads when using 4-wire sense.
