Section 3. Local Operation

Introduction

Once you have installed the power supply, it is ready to operate in local control mode

(that is, operation at the unit’s front panel).

• See “Standard Operation” for a brief explanation of Constant Voltage and

Constant Current Mode operation.

• See “Using Over Voltage Protection (OVP)” on page 38, “Using the Shutdown

Function” on page 39, and “Using Multiple Supplies” on page 40 for information

on these topics.

• See “User Diagnostics” on page 45, for troubleshooting information for the

operator.

•Turn to Section 4. Remote Operation for descriptions of remote programming

options and remote monitoring of the supply.

Standard Operation

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

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.

Operating

Modes and

Automatic

Crossover

The mode in which the power supply operates at any given time depends on the

combination of:

• output voltage setting V

SET

• output current limit setting I

SET

• resistance of the attached load R

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

variables.
