APT 400XAC Series User manual

400XAC
3 PHASE AC POWER SOURCE
For the following models:
430XAC and 460XAC
SAFETYCHECKLIST
KEEP unqualified/unauthorized personnel away from test area
ARRANGE test stations in a safe and orderly manner
NEVER touch products or connections during a test
STOP the test first in the event of a problem
BE SURE to use the appropriate AWG for your input and output cabling
TURN OFF the output when making any connections to the load
WARNING: THIS GUIDE WAS CREATED
FOR OPERATORS HAVING SOME FAMILIARITY
WITH AC POWER SOURCES AND HIGH
VOLTAGE/HIGH CURRENT TESTING APPLICATIONS.
AN AC POWER SOURCE PRODUCES VOLTAGES AND
CURRENTS THAT CAN CAUSE HARMFUL OR FATAL
ELECTRIC SHOCK. TO PREVENT ACCIDENTAL INJURY
OR DEATH, THESE SAFETY PROCEDURES MUST BE
STRICTLY OBSERVED WHEN HANDLING AND USING
AN AC POWER SOURCE.

CHANGINGTESTMODES
WARNING: LOCATE A SUITABLE TESTING AREA WITH A THREE-PRONG, GROUNDED OUTLET. BE
SURE THAT THE THREE PRONG GROUNDED OUTLET HAS BEEN TESTED FOR PROPER WIRING. MAKE SURE YOU
READ THE SAFETY CHECKLIST OF THIS GUIDE BEFORE USING THE INSTRUMENT.
The 400XAC includes two test modes that change the way in which the AC power source
operates. PROGRAM mode allows the operator to configure and run a test using steps and
memory locations within the AC power source’s menu. PROGRAM mode is designed for
advanced testing applications. MANUAL mode doesn’t utilize steps and memories, allowing
the operator to quickly run a test with basic test parameters.
1.Turn the instrument power switch ON.
2. From the Set screen, press the “<more>” soft key and press SYSTEM in the next screen.
3. In the System Parameters Menu, use the up or down arrow soft keys to highlight the
AUTO RUN parameter. Press EDIT to change the parameter.
4. Press CHANGE to toggle the parameter between PROGRAM and MANUAL mode. Press
ENTER to save changes and then press EXIT to return to the Set screen.
When the AUTO RUN parameter is set to PROGRAM mode, the Set screen will be displayed
as follows: (See Figure 1)
When the AUTO RUN parameter is set to MANUAL mode, the Set screen will be displayed
as follows: (See Figure 2)
(Figure 1. System Parameters Menu)
(Figure 2. System Parameters Menu)

CONSTANTCURRENTMODE
4.
USING THE 400XAC IN CONSTANT CURRENT MODE
1) Turn ON the OC FOLD parameter.
From the Set screen, press the “<more>” soft key and then press SYSTEM in the
next screen.
In the System Parameters Menu, use the up or down arrow soft keys to highlight the
“OC FOLD” parameter. Press EDIT to change the parameter.
Press CHANGE to set the highlighted parameter to ON. Press ENTER to save
changes and press EXIT two times to return to the Set screen.
2) Program a current Hi-Limit, which represents the constant current you will
provide to the load.
Press EDIT from the Set screen.
Use the up and down arrow soft keys to highlight the “A Hi-Lmt” parameter. Press
EDIT to change the parameter.
Use the Numeric Keypad to enter the desired current limit. Press ENTER to save
changes and then press EXIT to return to the Edit Parameters Menu. The limit set will
be the constant current output.
3) Program the voltage.
From the Edit Parameters Menu, use the up or down arrow soft keys to highlight the
“Voltage” parameter. Press EDIT to change the parameter.
Using the Numeric Keypad enter the voltage which should be set higher than the
nominal load voltage. This allows the current to adjust to the Hi-Limit value.
Press ENTER after you enter the voltage and press EXIT twice to return to the Set
screen.
