Front Panel Controls
The power supply is shipped ready to operate in local mode. The factory default
power-on setting is 0V, 0A with the DC output turned off.
This section describes the function keys, menu options, and control knobs that you
use to operate the power supply. (Additional details about the front panel keys,
control knobs, and display annunciators are provided in Section1, “About The XDC
Power Supply”.)
The next section (“Power Supply Operation” on page 64) provides details about
configuring and operating the power supply.
Function
Keys
Eight function keys are located on the front panel. Each is described below. For the
purposes of simple front panel control, you should understand the function of the
LCL/RMT, OUT ON/OFF, VOLTAGE, and CURRENT keys.
1. VOLTAGE: Lets you pre-set a setpoint before enabling it. To pre-set a voltage
setpoint, press VOLTAGE, use the Voltage knob or the numeric keypad to enter
a value, and then press ENTER to enable it. (See “Set Voltage” on page 64.)
This output can be changed while the output is OFF.
2. CURRENT: Lets you pre-set a setpoint before enabling it. To pre-set a current
setpoint, press CURRENT, use the Current knob or the numeric keypad to enter
a value, and then press ENTER to enable it. (See “Set Current” on page 64.)
This output can be changed while the output is OFF.
3. STORE: Lets you save power supply settings. (See “Store User Settings” on
page 77.)
4. OUT ON/OFF: This is a toggle key that enables and disables the power supply
output. Normally, you should leave the power supply in its Output Off state
when no load is attached or there is no need for DC output. (See “Turn Output
On or Off” on page 65.)
When the Out On annunciator is illuminated, the output is on. When the Out Off
annunciator is illuminated, the output is off.
5. LCL/RMT: This key lets you toggle between local and remote control. If the
RMT annunciator is illuminated, press LCL/RMT to return control to the front
panel, if local mode has been enabled by the controller. (See “Toggle
Local/Remote” on page 74.)
