Various functions 7-1 ON/OFF control The ON/OFF control function enables users to control ON/OFF of the output voltage without inputting or cutting it off.

(Over current protection circuit actuating current: 105% or above of the rated load current.) The converter automatically returns to normal operation as soon as the over current status is resolved. Holding of the over current status for over 30 seconds may result in damage, so resolve the over current status within 30 seconds. Also, if the converter does not return to normal operation automatically even if the over current status has been resolved, turn off the power once or turn the output OFF with an ON/OFF control and reactivate. Output Voltage[%] Characteristics in the over current mode 100 Note) A drooping characteristic may be seen in the over current protection characteristics as shown on the left.
