PAS SERIES Remote Control 4-5
4.1.2 Controlling the Output Voltage Using External
Voltage
This method is used to control the output voltage using an external
voltage (Vext) in the range 0 V to approx. 10 V.
To control the output voltage using external voltage, you must set CV
control of CONFIG settings to "1." For details on CONFIG settings,
see "3.2.4 Unit Configuration (CONFIG)".
Press the SET switch to check the preset 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 Chapter8 "Specifi-
cations".
In addition, leave the output of the external voltage
sour
ce (V
ext) floating. For details, see "2.5 Grounding
the Output Terminal".
• When using shielded wires for connection, protect the
u
nc
overed section of the shielded wire by using insu-
lation tubes with a withstand voltage greater than the
isolation voltage of the unit.
The output voltage (Eo) varies in the range of 0 to rated output volt-
age by setting the external voltage (Vext) in the range of 0 V to 10 V.
Eo = Ertg•Vext /10 [V] Vext = 10•Eo /Ertg [V]
Ertg: Rated output voltage [V]
For a portion of the 10 V, 20 V, 40 V, 60 V, and 80 V models, the
p
rod
ucts may be manufactured under the following specifications.
See also Chapter8 "Specifications".
The output voltage (Eo) varies in the range of 0 to rated output voltage by setting the
external voltage (Vext) in the range of approx. 0 V [0.5 V] to 10 V [9.5 V]. (The value
inside brackets is the design value.)
Eo = Ertg•(Vext-0.5) /9 [V] Vext = (Eo /Ertg•9) +0.5 [V]
