Remote Sensing
(only for R4G series)
If the [REMOTE SENSE ON/OFF] switch is turned ON while the sensing leads are disconnected,
the output value will be high and there is a possibility of damaging the load.
If the [REMOTE SENSE ON/OFF] switch is turned OFF while the sensing leads are connected, it
may result in a malfunction and damage the unit.
Do not use the remote sensing function when the units are connected in series or parallel.
With remote sensing operation, the output stabilization point can be set at a load or other point
instead of the output terminals of the unit.
Loss of the leads for the sensing operation is compensated up to 0.5V per one way.
Follow the procedures below to connect leads.
1. Turn off the unit.
2. Connect the leads from PIN 16 (+ Sense) and PIN 17 (- Sense) on the TB1 to the load.
3. Turn on the [REMOTE SENSE ON/OFF] switch on the rear panel of the unit.
４．
Turn on the unit.
Never reverse the polarity of the remote sensing leads. Doing so may result in
failure.
If the sensing leads and load wires become long when using the remote sensing
function, the inductance of the load wires may cause oscillation and prevent normal
output. In this case, it may be possible to solve the problem by connecting an
electrolytic capacitor of several hundred to several thousand μF at the load end.
