Connecting single loads, local sensing (default).
Fig.3
-
11 shows recommended load and sensing connections for a single load. The local sense lines
shown are default connections at th
e rear panel J2 sense connector. Local sensing is suitable for a
p-
plications where load regulation is less crit
i
cal.
3.9.8
Connecting single loads, remote sensing
Fig.3
-
12 shows recommended remote sensing connection for single loads. Remote sensing is used
whe
n, in Constant Voltage mode, the load regul
a
tion is important at the load terminals. Use twisted or
shielded wires to minimize noise pick
-
up. If shielded wires are used, the shield should be co
n
nected
to the ground at one point, either at the power supply
chassis or the load ground. The optimal point
for the shield ground should be determined by e
x
perimentation.
3.9.9
Connecting multiple loads, radial distribution method
Fig.3
-
13 shows multiple loads connected to one supply. Each load should beconnected to th
e power
supply’s output terminals using separate
p
airs of wires. It is recommended that each pair of wires will
be as short as possible and twisted or shielded to minimize noise pick
-
up and radiation. The sense
wires should be connected to the power supply
output terminals or to the load with the most critical
load reg
u
lation requirement.
