KEPCO ABC-DM SERIES - Manual (Page 3)

ABCCOND040104 A
These instructions are a quick reference for getting started with Kepco’s ABC power supply. For
more detailed information you are encouraged to read the accompanying Operator’s Manual.
CONNECT THE LOAD. The Sense terminals must be connected for the power
supply to work. For local sensing use the links supplied on the barrier strip at the rear.
For remote sensing, remove the links and make the 4-wire connections at your load. (See the Oper-
ator’s manual for more information.)
CONNECT SOURCE POWER. The power supply accepts a wide range of source
power: 85-264V a-c, 47-63 Hz or 400Hz. The POWER switch turns the unit on and off. The power
supply is equipped with a grounded North American 2-blade plug. Overseas users may substitute
their national plug; the chassis end is a standard 15A IEC connector.
LOCAL OPERATION
THE ALPHANUMERIC DISPLAY (LCD) . Operations are done from the keypad
and observed on the LCD. Optimize LCD contrast by pressing MENU until LCD reads
CONTRAST
,
then press numbers until viewing is optimum. The LCD displays the actual output voltage and cur-
rent and the operating mode: Local or Remote and constant voltage (CV) or current (CC). and a
blinking colon (:), or a blinking equal sign (=). Enter a command when you see a blinking colon (:),
enter numbers when you see a blinking equal sign (=). Six keys have a dual function (command/
number): the blinking colon (:) or equal sign (=) tells you which key function is effective.
USING THE KEYPAD . Use ENTER to accept numbers entered or execute a command.
Use CLEAR if you make a mistake and don’t want to change the status quo. Valid entries are
accompanied by a short beep; invalid entries by a longer buzz. (The speaker can be disabled by
pressing MENU until LCD display
SPEAKER
and entering 0.)
OUTPUT SETTINGS. V SET sets output voltage; I SET sets output current. Depending
on the mode (CV or CC), one setting acts as a limit. (For example, in CC mode, V SET is the volt-
age limit and I SET is the output current setting.) The operating mode (CC or CV) is determined by
the load combined with the V SET and I SET settings. The " and # keys can be used to increase
or decrease output voltage (CV mode) or current (CC mode) by the least amount possible (approxi-
mately the maximum rating divided by 4000).
OUTPUT ON/OFF. (ON) enables programmed output settings to appear at the output
(OFF) sets output voltage and current to zero and the LCD reads “
Output is OFF
’”
RESET. Use RESET to restore the power-on defaults (output on, V SET and I SET at zero, OV
SET and OC SET at approximately 10% above rated output).
PROTECTION. OV SET and OC SET establish protection for overvoltage and overcurrent
conditions. If the output attempts to exceed programmed OV SET or OC SET values, the LCD indi-
cates which condition occurred, and the output goes to zero. RESET or cycle the power supply off
and on to recover.
CALIBRATION. CALIB leads you through a digital calibration procedure (password pro-
tected). The initial password is the voltage rating plus current rating (e.g., 1010 for ABC 10-10DM).
You can change it using the MENU. The previous calibration is saved and can be restored. The
original factory calibration can also be restored. (See Section 4 of the Operator’s Manual.)
