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.
In addition, brief descriptions are provided of Constant Voltage and Constant Current
modes. See page 49.
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 source.
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 ON is illuminated, press the OUT ON/OFF
button to disable it. The OFF annunciator should now be illuminated. For an
illustration of the annunciators and their locations, see Figure 1.2.
WARNING- Shock Hazard
The factory setting for Power ON is 0V and 0A. These settings can be changed 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.
