3 Operating the Power Supply Locally

Normal Operation

The power supply has two basic operating modes: constant voltage and constant current mode. In constant voltage mode, the power supply regulates the output voltage at the selected value, while the load current varies as required by the load. In constant current mode, the power supply regulates the output current at the selected value, while the voltage varies as required by the load. The mode in which the power supply operates at any given time depends on the voltage setting, current limit setting, and the load resistance.

Constant Voltage Mode

 

When the power supply is operating in constant voltage mode, the CV

 

indicator on the front panel illuminates.

 

Adjustment of the output voltage can be made when the output is

 

enabled (On) or disabled (Off). When the output is enabled, simply

 

rotate the voltage knob to program the output voltage.

 

When the output is disabled, press the LIMIT button and then rotate

 

the voltage knob. The DC VOLTS display will show the programmed

 

voltage for 5 seconds after the adjustment has been completed and

 

then indicate OFF.

 

The voltage knob can be set to coarse or fine resolution. Press the

 

FINE button to select finer resolution. The FINE indicator turns on.

 

If you cannot adjust the voltage to the value that you desire, the power supply

NOTE

 

may be operating at its current limit. Check the load condition and the current

 

limit setting. Also, the voltage cannot be programmed lower than about 5%

 

above the UVL setting, or higher than about 5% below the OVP setting.

 

 

Constant Current Mode

When the power supply is operating in constant current mode, the

CC indicator on the front panel illuminates.

Adjustment of the output current limit can be made when the output is enabled (On) or disabled (Off). When the output is enabled and in constant current mode, simply rotate the current knob to program the current limit. If the output is in constant voltage mode, press the LIMIT button and then rotate the current knob. The DC AMPS display will show the programmed current for 5 seconds after the adjustment has been completed and then indicate the actual output current.

When the output is disabled, press the LIMIT button and then rotate the current knob. The DC AMPS display will show the programmed current for 5 seconds after the adjustment has been completed and then go blank because the output is off.

The current knob can be set to coarse or fine resolution. Press the

FINE button to select finer resolution. The FINE indicator turns on.
