3.5.2.2 Over Current Foldback (OC-FOLD)
At the TESTING subpage 1 (BASIC mode), users are allowed to enable the OC-FOLD
mode. Thus when the output current exceeds the set value of maximum output cur-
rent, the product can automatically adjust the output voltage to maintain the output
current at the up limit; when the output current falls back to the up limit, the output
voltage will then return to the set value of output voltage(refer to Subsection 3.3).
The response time starting from the output current exceeding the up limit till fall-
ing back to the up limit is ≤1.4S. In practical applications, it can effectively improve
the starting capacity for the rectifier loads and the electric motor load.
When OC FOLD mode is disabled, AFV-P series will shut down the output if the out-
put current were to exceed the set value of maximum output current.
Figure 3.27 Principle of OC-FOLD Operation
The procedures of enabling the OC-FOLD mode are given as below:
1. Press the item twice to switch the icon status from
OFF to ON.
2. Press the icon to confirm and enable the OC-FOLD mode.
