OPERATION
Connect the AC power cord and select the corresponding AC voltage according
to the back label, the connect the AC power cord to the socket on the back panel.
press the power switch to turn the power on. The display initializes
showing the model of the machine and the setting level which is recalled
from the last use.
Press the power switch again to turn the power off.
Output Control and Output Shutdown Memory of Power Supply
• Press Output will be turned on, the positive and negative terminals will output
according voltage and the output indicator light will be lit ON.
• Press and hold for one second, and then the output indicator will be lit ON. At this
time, the machine will memorize the output status before shutting down, and the last status
will be exactly what the power supply is set to when you power ON next time.
Note: If there are any of the following conditions, the output will automatically turn off:
• OVP turns on and then there is unusual voltage on the input terminal which is
more than the setting voltage.
•
OCP turns on and then there is unusual current on the output terminal which is
more than the setting current.
•
Recalling other setups from the memory.

SAVE SETUP
Contents
The following list shows the setup contents:
• Fine/coarse knob editing mode
• Beep on/off
• Output voltage/current level
• Output on/off (The shutdown memory must be set to make it saved)
Panel Operation
Press one of the four buttons (M1, M2, M3, M4) and the LED light
turns on accordingly. After adjusting the value, it is automatically
saved, once the LED light stops blinking.
RECALL SETUP
The front panel settings can be recalled from one of the four internal memories.
Press any button M1 to M4.
For example, the memory of the panel setting is recalled in M1.
After you recall M4, rotate the shuttle knob and then M5 is recalled.
If the memory indicator is lit on the panel of lights, then the current memory is recalled.
Note: When a setting is recalled the output automatically turns off.

• Data pow control: None
• Run this query command via the terminal application, such as MTTTY (Multi-threaded TTY).
• This should return the identification information: Manufacturer, model name, serial number,
• Connect the USB.
• The power supply will automatically connect. After a normal connection, there will be an
audible indication from the power supply itself.
• The panel keys are locked, so the power supply can only rely on the remote control.
• Close the remote control software.
