6.3 Start-up sequence
（
starting-up delay / rising up
）
TON_DELAY [ 60h ] can set start-up delay time until output voltage is risen up after input
condition is met. When setting more shortly than the start-up delay-characteristics of
the power, there is not a change in the start-up delay time.
TON_RISE [ 61h ] command can set. rising up time.(only CHS400-I)
But, when setting is more shortly than the start characteristic of the power, there is not
a change in the start time. (For the details of the value setting, refer to clause 10.)
6.4 Output voltage setting (only CHS400/500-I)
You can set output voltage of power supply by command as shown Table 6-2.
*1: Switching by OPERATION [ 01h ] command. Initial value is VOUT_COMMAND [ 21h ].
Output voltage becomes value shown in below format.
Note
Output voltage of power supply = VOUT_TRIM [ 22h ] value of s or VOUT_MARGIN_HIGH [ 25h ] Value of setting
3
VOUT_MARGIN_LOW [ 26h ]
or VOUT_MARGIN_LOW [ 26h ] Value of setting
