4-4 External Voltage Control

*

4-4-1 Voltage Control by External Voltage (LV)

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

4-4-2 Current Control by External Voltage (LC)

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

*

External voltage fluctuation directly influences 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 to 100%.

4-5-2 External Volume Current Control (LRc).

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