4.3.4 Controlling output current with external voltage
This method is used to control output current using 0 V to approx. 10
V external voltage.
• The insulation of the external voltage source (Vext)
and the cable connecting it should be greater than
the isolation voltage of the unit. For details on the iso-
lation voltage of each model, see Chapter 7 "Speci
fi -
cations".
In addition, leave the output of the external voltage
source (Vext)
fl oating. For details, see "2.6 Output
Terminal Isolation".
• When using shielded wires for connection, protect
the uncovered section of the shielded wire by using
insulation tubes with a withstand voltage greater than
the isolation voltage of the unit.
• Never attempt to carry out wiring to the control termi-
nals with the POWER switch turned ON. Otherwise,
electric shock or failure of the internal circuit may be
caused, and may result in improper operations.
• When controlling the unit using an external voltage source
which has a quick rising time relative to the capacitive load,
the phase control circuit of the unit cannot respond to the
external voltage, which may cause AC components to be
superimposed on the rising waveform.
Connection and setup procedure
1. Turn off the OUTPUT switch.
2. Turn off the POWER switch.
3. Turn the CURRENT contro knobl fully clockwise.
