Section 3. Local Operation

Introduction

Once you have installed the power supply and have connected both the AC input power and the load as covered in Section 2. Installation, the power supply is ready to operate in local control mode (that is, operation at the unit’s front panel).

•See “Standard Operation” on page 57 for a brief explanation of Constant Voltage and Constant Current Mode operation and see page 61 to page 70 for more about power supply functions such as over voltage protection, shutdown function, over temperature protection, and using multiple supplies.

•See “User Diagnostics” on page 71 for troubleshooting information for the operator.

•Turn to Section 4. Remote Operation for descriptions of remote programming options and remote monitoring of the power supply.

This power supply has two basic operating modes: Constant Voltage Mode and

Constant Current Mode, and two control modes: Local Control Mode (default setting) and Remote Programming Mode. Both operating modes are available regardless of which control mode is used.

Whether controlled by local or remote programming, 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 combination of:

•output voltage setting VSET

•output current limit setting ISET

•resistance of the attached load RL

See Figure 3.1 for a graphical representation of the relationships between these variables.
