Power Supply Function
4.3 Set the Output Power
Press [P-set], the interface displays “Plim=0.00W” (Upper limit of power) , the
lower limit of the power is 0.
The range of power settings is between the data ranges defined in the specifica-
tions. When [P-set] key is pressed, the key light is lit and the output power value
can be set. Press numeric keys or rotate the knob to adjust the value in the
power setting area indicated by the cursor. This value takes effect when you
press [Enter].
4.4 Config Menu for Power Supply
In this chapter, the setting items under the configuration menu are described in
detail.
4.4.1 Set the CC/CV Priority Mode
CV Priority
In CV priority mode, the output is controlled by a constant-voltage feedback
loop, which maintains the output voltage at its programmed setting as long as
the load current remains within the current limit settings. CV priority mode is
best suited for use with resistive or high impedance loads, and loads that are
sensitive to voltage overshoots. Do not use CV priority mode with low-impe-
dance sources such as batteries, power supplies, or large charged capacitors.
In CV priority mode, the output voltage should be programmed to the desired
value. A current limit value should also be set. The current limit should always
be set to a value that is greater than the actual input current requirement of the
external load. The following figure shows the CV priority operating locus of the
output.
