Safety Guidelines
•Avoid severe impacts or rough handling that leads to
damage.
•Do not disassemble unless you are qualified as
service personnel.
AC INPUT •AC Inut Voltage: 110V / 120V / 220V / 230V , 50 / 60 Hz
Connect the protective grounding conductor of the AC
power cord to an earth ground, to avoid electrical
shock.

Front Panel Overview
Ka3300 series are multiple-channel digital control and
programmable power supplies, which reflect a variety of
features about digital control, such as the fast recall, and
the parameters' setting of Overcurrent Protection and
Overvoltage Protection independently to provide the
convenient and reliable operation environment. They use
efficient radiators and low-speed & stepless-speed fan,
which is quiet and efficiently cooling during operation.
Furthermore, the machine employs an industrial design,
and can work reliably and uninterruptedly for a long time.
And they can be used in the laboratory, the plant aging
and the testing.

Function Introduction
1. The Operation and Outputs of Voltage and Current
1. Press the button CH1 and then the CH1 display
indicator blinks; press CH1 again and then some voltage
digit on the channel 1 blinks. At this time, the voltage value
can be set by adjusting the voltage adjustment knob. Then
press the button CH1 again while the voltage digit is
blinking to switch into the current digit blinking, when the
current value can be set by adjusting the current adjustment
knob. Furthmore, when the voltage or current digit blinks,
press the voltage or current adjustment knob and the
blinking digit (i.e. the adjusting digit) can be changed.
2. After the voltage and current values are set, press the
button ON/OFF to turn on the output, when the ON indicator
on the display will be switched on; press the button ON/OFF
again to turn off the output and at this time the ON indicator
will be switched off.
2. The Series and Parallel Operation
1. The Series Operation: Press and hold the button CH1 for
3 seconds to be in the series mode. When the SER
indicator on the display lights on, it means the power
supply is in the series mode now. At this mode, CH2 is the
master operation while CH1 is the slave operation, when
the CH1 operation is shielded. At this time, press the button
ON/OFF and then the output can be turned on or off. And
the output connection is as shown in the figure:
2. The Parallel Operation: Press and hold the button CH1
for 3 seconds to be in the parallel mode. When the PARA
indicator on the display lights on, it means the power
supply is in the parallel mode now. At this mode, CH2 is the
master operation while CH1 is the slave operation, when
the CH1 operation is shielded. At this time, press the button
ON/OFF and then the output can be turned on or off. And
the output connection is as shown in the figure:

3. Recall to output
In any state, just press the buttons M1 M5 and then the
according memories can be recalled.
4. The Operation of Overcurrent Protection
78
Pressandholdthebutton“OCP”for3seconds
to enter the mode of OCP setting, when the
indicator “OCP SET” lights on. And the current
values on both CH1 and CH2 display the OCP
values accordingly. By adjusting the current knob,
the OCP value can be changed. Press and hold the
button “OCP” again for 3 seconds to exit.
Furthermore, press the button “OCP” to switch
on the Overcurrent Protection (OCP) mode and the
indicator “OCP” is turned on; press the button “
OCP” again to shut down the OCP mode and the
indicator“OCP”willbeturnedoff.WhentheOCP
modeison,ifthecurrentvalueontheloadorthe
setting current is more than that in the OCP SET,
theoutputwillbecutoff.
5.The Overvoltage Protection (OVP) Setting and Switching on
Pressandholdthebutton“OVP”for3secondsto
enter the mode of OVP setting, when the indicator
“OVP SET” lights on. And the voltage values on both
CH1 and CH2 display the OVP values accordingly. By
adjusting the voltage knob, the OVP value can be
changed. Press and hold the button “OVP” again for
3 seconds to exit. Furthermore, press the button
“OVP” to switch on the Overvoltage Protection
(OVP) mode and the indicator “OVP” is turned on;
press the button “OVP” again to shut down the OVP
mode and the indicator “OVP” will be turned off.
When the OVP mode is on, if the voltage value on the
load or the setting voltage is more than that in the
OVPSET,theoutputwillbecutoff.
6. Keyboard Lock
Press and hold the voltage adjustment knob for 3 seconds,
and then the front panel will be locked; press and hold it
again for 3 seconds, and then it will be unlocked.
7. Beep ON/OFF
Press and hold the current adjustment knob for 3 seconds,
and then the beep will be turned off. Press and hold it again
for 3 seconds, it will be turned on.

COM setting Set up the COM port inside the PC according to the
following list.
