SK4-15

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

output voltage.

 

 

 

 

This pin floats at 2.5V nominal with respect to

 

 

 

 

negative output (O/P @ 54.5V)

 

 

 

 

Applying a DC voltage adjusts the output by –1V/V.

 

 

 

 

(For 1V swing on program pin the output voltage

 

 

 

 

changes by –1V)

 

 

 

 

The programming voltage range is 0V – 14V, giving a

 

 

 

 

max adjustment range of 57V to 43V.
