2.5.1Current Limit Programming
Input | Description | Controller | Connector |
|
| Type |
|
Current Limit | Connect a DC voltage to this pin (referenced to | Rear Access | |
Program | signal common or | Front Access | |
| output current limit point. |
|
|
| Current limit is programmed down 1A per 1.5V |
|
|
| program voltage. Max program voltage 7.5V. |
|
|
5V aux | 5V aux can be used to program down current limit | Rear Access | |
| level by linking to program pin. | Front Access |
The system output current limit can also be set to either the standard “High” (100%) level or “Low” (70%) level by using SK13.
For “High” current limit level link pins 1 and 2 (default setting)
For “Low” current limit level link pins 2 and 3
Selecting “Low” current limit level will program down each rectifiers current limit level to roughly 70% of the default level. (See section 2.1.1 for default levels). This is the same as connecting the 5V aux pin to the current limit program pin as detailed above.
Note/ using both programming methods together will not double the effect
