4.3.1 Controlling output voltage with external resis-
tor
This method is used to control output voltage using a 0
Ω
to approx.
10 k
Ω
external resistor.
• The insulation of the external resistance (Rext) and
the cable connecting to it should be greater than the
isolation voltage of the unit. For details on the isola-
tion voltage of each model, see Chapter 7 "Speci
fi ca-
tions".
• When using shielded wires for connection, protect
the uncovered section of the shielded wire by using
insulation tubes with a withstand voltage higher 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.
Connection and setup procedure
1. Turn off the OUTPUT switch.
2. Turn off the POWER switch.
3. Set the control switches S1 and S2 as shown in Fig.4-10.
4. Connect an external resistor across the control terminals
[4] and [5] as shown in Fig.4-10.
• If Rext is disconnected, excessive voltage may be
applied to a load. Connect the Rext to the control
terminals
fi rmly.
• To use Rext which consists of a multiple number of
fi xed resistors and a switch, and select one of them
for control, use a short circuit type or continuous type
switch.
