Section 3. Operation
Overview
Once you have installed the power supply and connected both the AC input power
and the load as explained in Section 2, the power supply is in its default
configuration and is ready to operate in local control mode.
Section 3 begins by explaining how to power on and power off the power supply. It
then provides information about configuring the power supply, and also gives
procedures for operating the supply via the front panel controls and menu functions.
In addition, brief descriptions are provided of Constant Voltage, Constant Current,
and Constant Power modes. See “Power Supply Operation” on page 64.
Powering ON
the Power
Supply
To power on the power supply:
1. Ensure that the AC power switch is OFF.
2. Connect the unit to an AC outlet.
3. Turn on the front panel AC power switch.
After a short power-on delay, the digital meters on the front panel and the CV
annunciator illuminate. The voltmeter and ammeter displays should read zero.
Check the front panel annunciators. If OUT ON is illuminated, press OUT ON/OFF
to disable it. The OUT OFF annunciator should now be illuminated. For an
illustration of the annunciators and their locations, see Figure 1.5.
WARNING- Shock Hazard
The factory setting for Power ON is 0V and 0A with the output OFF. These settings
can be customized by end users. If you suspect that the power supply has been used
by someone else since it was received from the factory, be prepared for the unit to
power ON with a live DC output.
