CHAPTER 5 LOCAL OPERATION

5.1 INTRODUCTION

This Chapter describes the operating modes that are not involved in programming and monitoring the power supply via its serial communication port (RS232/RS485) or by remote analog signals. Ensure that the REM/LOC LED on the front panel is Off, indicating Local mode. If the REM/LOC LED is On, press the front panel REM/LOC button to change the operating mode to Local.

-For information regarding Remote Analog Programming, refer to Chapter 6.

-For information regarding usage of the Serial Communication Port, refer to Chapter 7.

5.2 STANDARD OPERATION

The power supply has two basic operating modes: Constant Voltage Mode and Constant Current Mode. The mode in which the power supply operates at any given time depends on the Output Volt- age setting, Output Current setting and the load resistance.

5.2.1 Constant Voltage Mode

1.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.

2.While the power supply operates in constant voltage mode, the VOLTAGE LED on the front panel illuminates.

3.Adjustment of the Output Voltage can be made when the power supply output is enabled (Output On) or disabled (Output Off). When the output is enabled, simply rotate the VOLTAGE encoder knob to program the output voltage. When the output is disabled, press the PREV button and then rotate the VOLTAGE encoder knob. The VOLTAGE meter will show the programmed Output Voltage for 5 seconds after the adjustment has been completed. Then the VOLTAGE meter will display “OFF”.

4.Adjustment resolution can be set to coarse or fine resolution. Press FINE button to select between the lower and higher resolution. The FINE LED turns On when the resolution is set to FINE.

NOTE

If after completing the adjustment, the display shows a different value than the setting, the power supply may be at current limit. Check the load condition and the power supply Output Current setting.

NOTE

The maximum and minimum setting values of the output voltage are limited by the Over Voltage protection and Under Voltage limit setting. Refer to Sections 5.3 and 5.4 for more details.

5.2.2 Constant Current Mode

1.In constant current mode, the power supply regulates the Output Current at the selected value, while the voltage varies with the load requirement.

2.While the power supply is operating in constant current mode, the CURRENT LED on the front panel illuminates.

3.Adjustment of the Output Current setting can be made when the power supply output is enabled (Output On) or disabled (Output Off).

-Disabled output (Off): Press PREV button and then rotate the Current encoder knob. The CURRENT meter will show the programmed Output Current limit for 5 seconds after the adjust- ment has been completed. Then the VOLTAGE meter will display “OFF”.
