Basic Connection (Local sensing)
(1)
Connect “+S” terminal to “+Vm” terminal with sensing wire
(2)
Connect “-S” terminal to “-Vm” terminal with sensing wire
(3)
Connect “CNT+” terminal to “CNT-” terminal with wire
Please use attached connector for each connection.
2-4.
Remote Sensing (+S, -S terminal)
(1)
Connect “+S” terminal to “+” terminal of load with sensing wire
(2)
Connect “-S” terminal to “-” terminal of load with sensing wire
(3)
Connect “CNT+” terminal to “CNT-” terminal with wire
This function compensates voltage drop of wiring from output terminals to load terminals. Connect “+S” terminal to “+”
terminal of load and “-S” terminal to “-” terminal of load with sensing wires. The total line voltage drop (+ side line and
- side line) shall be less than 0.3V. In case that sensing lines are too long, it is necessary to put an electrolytic capacitor
in following places:
(1)
across the load terminal,
(2)
between “+S” terminal and “+V” terminal,
(3)
between “
‐
S” terminal and “
‐
V” terminal.
When the function of remote sensing is not in use, cS terminal to +Vm terminal, and –S terminal to –Vm
terminal by the attachment connector. If remote sensing terminals are opened, the stability and the accuracy of the
output deteriorated. Therefore, teS, -S must be connected.
