4.2.3 Setting of output rise time and transition time
Display and edit area [Write] Button
Item Overview
CV Rising T ime Set the time to specify the voltage slew rate (dv / dt) at the start of output.
T he value is specified as the time required for the CV reference value to change from 0% to 100%.
Register value can be set in the range of 20 [ms] to 10000 [ms]. (factory setting: 20 ms)
CC Rising T ime Set the time to specify the current slew rate (di / dt) at the start of output.
T he value is specified as the time required for the CC reference value to change from 0% to 100%.
Register value can be set in the range of 20 [ms] to 10000 [ms]. (factory setting: 20 ms)
CV T ransition Time Set the time to specify the voltage slew rate (dv / dt) when the CV reference value is changed
during steady output at RC ON state.
T he value is specified as the time required for the CV reference value to change from 0% to 100%.
T he set time is applied when the next AC turn-on or remote control turns OFF
→
ON.
Register value can be set in the range of 20 [ms] to 10000 [ms]. (factory setting: 20 ms)
CC T ransition Time Set the time to specify the voltage slew rate (di / dt) when the CC reference value is changed
during steady output at RC ON state.
T he value is specified as the time required for the CC reference value to change from 0% to 100%.
T he set time is applied when the next AC turn-on or remote control turns OFF
→
ON.
Register value can be set in the range of 20 [ms] to 10000 [ms]. (factory setting: 20 ms)
* It depends on the system configuration whether or not actual change in output is in accordance with the set value.
By clicking the [Write] button arranged for each item, the changed data is written to GXE.
When a capacitive load such as a battery is connected to the power supply,
overcurrent may occur at the time of output start or change of command value.
In that case, there is a possibility of improvement by adjusting the slew rate
with the register of this section.
