４ Advanced Operation

４－４ External voltage control

Note1

4-4-1 Voltage control by external voltage (LV)

0-10Vdc external voltage can control the output voltage within the range of 0-100%.

4-4-2 Current control by external voltage(LC)

0-10Vdc external voltage can control the output current within the range of 0-100%.

Note

１．

External voltage fluctuation directly influences on the output. The external voltage should be stable.

４－５ External volume control

4-5-1 External volume voltage control (LRv)

The external volume 5kΩ can control the output voltage within the range of 0-100%.

4-5-2 External volume current control (LRc)

The external volume 5kΩ can control the output current within the range of 0-100%.
