3.2.1 Regarding the Input Power Supply Cord

Depending on the power rating of the equipment, the pre-installed power cord will vary.

Jumlah	Note
①	Low-power devices come pre-installed with standard mains power plugs
②	High-wattage appliances come pre-installed with thicker power cords; do not plug them directly into low-wattage outlets.

3.2.2 Pengenalan Panel Belakang dan Pengkabelan

Jumlah	Note
① Kabel daya	Connect the device to an appropriate power source
② Power Circuit Breaker
③ Output Terminals	Connect to your DC load
④ Sampling Terminal	It also connects to your DC load, allowing you to obtain a more accurate load-side voltage. If you require high voltage sampling accuracy, please connect it; leaving it unconnected does not affect the DC power supply’s output functionality.
⑤ Ground Terminal	If your load requires a ground connection, you can connect its ground wire to this terminal.
⑥ Communication Port	If you need the device to communicate with a computer, connect a USB/RS232/RS485 cable to the computer.

Note: If the sampling terminals are connected, this is a 4-wire sampling configuration, which eliminates cable voltage drop; if the sampling terminals are not connected, cable voltage drop is included.

4. Pengoperasian Peralatan

4.1 Keluaran Tegangan Konstan

4.1.1 Current Adjustment

If constant-voltage output is required, the current serves as a current-limiting reference. You can set it directly to the maximum value, or at least to a value sufficient to maintain the set constant voltage. If the current is set too low, the current limit will be triggered, and constant-voltage output cannot be maintained.

petunjuk	Note
①	Press the current adjustment knob, and the last digit in the current display window will begin to flash.
②	Turn the flow control knob to change the digit in that position.
③	Continue pressing the flow adjustment knob to cycle through the other digits, and use the same method to change each digit.
④	After completing the setup, wait 2 seconds; the device will automatically exit setup mode.

4.1.2 Adjusting the Voltage

If a constant-voltage output is required, set the voltage to the load’s rated voltage.

petunjuk	Note
①	Press the voltage adjustment knob, and the last digit of the voltage display will begin to flash.
②	Turn the volume control knob to change this digit.
③	Continue pressing the voltage adjustment knob to cycle through the other digits, and use the same method to change that digit.
④	After completing the setup, wait 2 seconds; the device will automatically exit setup mode.

4.1.3 Turn Output On/Off

Example: I need a constant-voltage output of 22V. Set it up as follows.

Jumlah	Note
①	Press the output switch to activate the output.
②	The constant-voltage indicator light is on, and the device is in constant-voltage output mode.
③	The voltage display window shows the output voltage, which matches the set value.
④	The current display window shows the output current. It does not need to match the set value, but the set value must be higher than the actual value; otherwise, constant-voltage output will not be possible.
⑤	The power display window shows the output power.
⑥	The Equivalent Impedance window displays the equivalent impedance of the current output line.

4.2 Keluaran Arus Konstan

4.2.1 Adjusting the Voltage

If constant-current output is required, the voltage serves as the over-voltage limit reference. You can set it directly to the maximum value, or at least to a value that satisfies the set constant-current value. If the voltage is set too low, it will trigger the over-voltage limit, and the constant-current output cannot be maintained.

For instructions on adjusting the voltage, see Section 4.1.2.

4.2.2 Current Adjustment

If a constant current output is required, set the current value to the load’s rated current.

For instructions on adjusting the current, see Section 4.1.1.
