Control Descriptions

2.3.1  Power On/Off Button

Used to turn the power ON and OFF.

2.3.2  Voltage and Current Adjustments

•  Voltage Adjustment:

-  Sets  the  regulated  voltage  output  by  turning  the  large  knob 

(COARSE adjustment) to the right (increases output) or left 

(decreases output).

-  Sets the regulated voltage output by turning the small knob 

(FINE  adjustment)  to  the  right  (increases  output)  or  left 

(decreases  output).  The  FINE  adjustment  range  represents 

approximately 10% of the main range.

-  The value of the voltage output is displayed in real time on the 

green display.

•  Current Adjustment:

-  Adjust the value of the current limit by turning the knob to the 

right (increases output) or left (decreases output).

-  The current value displayed is the value of the output current 

on the red display.

2.3.3  Current “LIMIT” LED

The AX  Series  Power  Supplies  provides  the  ability  to  limit  the  current 

output. When the “limit” is reached, the power supply will switch to “current” 

regulation to ensure the current output and drops the voltage regulation.

Setting a Current Limit: 

•  Short the output terminals, and adjust the current to the desired  

limit (you may need to have a little voltage for the current to flow). 

The value of current flow will be displayed on the appropriate dis

-

play.

•  Turn the voltage output off and connect to the sample. As the volt

-

age is increased, if the current reaches the set limit, the “LIMIT” 

LED will turn on, and the current will no longer increase. 

•  The current limit may be overridden simply by increasing the   cur

-

rent output manually.
