3-3. Remote Voltage Sensing

When a electric load is connected from power supply's output terminal, voltage regulation will o
from output terminal. Therefore, to supply accurate power to load, Remote Voltage Sensing
(V-Sensing) can be used. Please read below to use V-sensing correctly.

CV Regulation

Specification's voltage Load Regulation attribute.
While using V-Sensing, because of the change from current, 5mV should be added to this a
S Point and +output terminal. Because, sensing lead line is power supply's feedba
It will stable when the resist value is below 0.5Ω.

Output Rating

Please read below about specification's output voltage & current.
When you use V-Sensing, the load leadline's voltage drop point will be added to it's load.
Therefore if you print out more than maximum voltage, V-sensing mode will not guarantee y
and power supply will be unregulated mode Also when each load leadline rise more than 1

and power supply will be unregulated mode. Also, when each load leadline rise more than 1
the instrument will be unregulated not related to maximum voltage.

What is UnRegulated mode? Disabled power supply's CC and CV

Note

Output Noise

Noise from power supply's output can lead to a serious problem in Load Regulation.
Please follow the steps below :

▌twist sensing leadlines togeter to decrease noise from outside.
▌connect in a straight line with sensing leadline, when it's near load leadline.
▌cover sensing leadline when it's disclosed.
▌Noise cover equipment should be connected to GND in the closest location.
