Basic Operation
PAD-L
3.2.2
Using as a constant voltage power supply
CAUTION
•
A current limit value and required voltage value must be preset to
use the unit as a constant voltage power supply. To preset these
values, an actual voltage must be output; disconnect any load that
may be connected.
1.
Turn on the POWER switch.
2.
Make sure the C.V or C.C lamp lights up.
3.
While pressing the CURRENT/VOLT. LIMIT switch, set a current value
that can be applied to the load by turning the CURRENT setting knob.
The value set here is used as a current-limiting value.
The CURRENT/VOLT. LIMIT switch simply displays the present voltage and
current settings. It has no memory feature.
4.
Set the requested voltage by turning the VOLTAGE setting knob.
5.
Turn off the POWER switch.
6.
Connect a load to the output terminals.
7.
Turn on the POWER switch.
8.
The C.V lamp lights up to indicate that the unit is in constant voltage
mode.
CAUTION
•
For the loads listed below in which sudden voltage application is
undesirable, follow steps 1 to 3 above, then follow steps 4 to 9
below.
a. Loads of unknown resistance
b. Loads whose resistance varies over a wide range
c. Loads of large inductance
4.
Turn the VOLTAGE setting knob fully counterclockwise.
5.
Turn off the POWER switch.
6.
Connect a load to the output terminals.
7.
Turn on the POWER switch.
8.
Turn the VOLTAGE setting knob slowly counterclockwise to raise
voltage gradually.
9.
The C.V lamp lights up to indicate that the unit is in constant voltage
mode.
