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 t
he 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 lo
ad.
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.
