6-4. Variable output current (variable constant current output setting value)
Output current can be set using an external signal (communication function, CC terminal external
voltage application, CC terminal external current application).
In constant current operation, when the output voltage reaches the value set by the built-in volume or
external signal (communication function, CV terminal external voltage application, CV terminal
external current application), it switches to constant voltage operation.
When using the product at a voltage exceeding the rated voltage, it is necessary to derate the output
current so as not to exceed the maximum output power.
6-4-1. Variable by external power (CC terminal external voltage applied)
The constant current output value setting can be changed by applying an external voltage in the
range of 1-5V between the CC and AG terminals.
Note that if no external voltage is applied to the CC terminal when the input is turned on, the power
output will be a constant voltage output.
Internal resistance between CC terminal and AG terminal is 250Ω. Pay attention to the current
limit of the external voltage source.
