- This product is meant for indoor and home use ONLY.
- To prevent electric shock, DISCONNECT the power plug when replacing the fuse or conducting other repairs.
- Fuses of the same type and rated specification MUST be used for replacement.
- This product is not meant for users that are inexperienced (including children), have physical, sensory, or mental disabilities unless these users are guided and monitored by their responsible guardians. Take good care of the children and DO NOT allow children to play with this product.
- Manage the children, and ensure that they DO NOT play with this product.
- To prevent the risk of danger, ONLY the manufacturer, manufacturer-appointed service provider, or certified professionals are allowed to replace the power cord if the power cord is damaged.
- ANY reparation services shall ONLY be conducted by the manufacturer-appointed service provider. This product does not include spare parts for users to conduct self-reparations.
- To reduce the risk of fire hazard or electric shock, keep the product indoor and DO NOT expose this product in the rain or humid environments. Read the instruction manual before use.
- To ensure your safety, TURN OFF the power switch when the operation is complete. DISCONNECT the power cord if the product is not in use for an extended period.
- The product includes a detachable short power cord to reduce the risk of cable tangling or tripping.
- A longer detachable power cord is available, use the power cord with utmost caution.
- When using the long detachable power cord:
- The electrical ratings on the detachable power cord or extension cord MUST BE identical to the electrical ratings of this product.
- The extension cord should be a grounding three-prong power cord.
- Organize the longer power cord well. Ensure the power cord is on the surface of the table or work desk to avoid tripping, obstructing, or accidental pulling (especially for children).
- Reserve sufficient space around the power supply to allow heat dissipation and cooling.
- DO NOT use the product in environments where the ambient temperature is over 40°C.

I. Applications & Features
This regulated DC power supply is developed specifically for scientific research, product development, test labs, schools, electronic assembly lines, and electronic repairs.
- The voltage regulation is highly stable with great load capacity and low ripple. This power supply comes with a complete set of functions including short circuit protection, overcurrent protection and over-heat protection functions.
- This power supply uses a toroidal transformer, minimizing losses and reduced heat generation.
- The product is equipped with ports with quick-access non-adjustable voltages of 5V, 8.4V, and 12V, as well as three pre-set channels to switch among multiple voltage settings quickly.
- The product offers modes including constant current output, overcurrent auto-stop, and overcurrent auto-resumption mode. Users can choose the appropriate mode based on their applications.
- The product comes with two 5V USB ports and 6 USB ports in parallel with the 30V output. Connect the load to the correct rating to prevent damaging the device.

III. OPERATION
- Connect the power supply's power cord to an electrical outlet.
- Turn ON the power supply's master power button [⚡] and set the desired voltage value using the voltage adjustment knob [⚙️].
- Connect the load to the power supply based on the correct polarity [➕/➖]. Press the output ON/OFF button [▶️/⏹️] once and the power supply will begin powering the load.
- When the operation is complete, press the output ON/OFF button [▶️/⏹️] to stop the output. DISCONNECT the load, and turn OFF the power supply. DISCONNECT the power cord when the power supply is not in use for an extended period.
- Constant Current Output Mode, Overcurrent Protection Mode (Auto-Recovery and No-Recovery):
- Constant Current Output Mode: When the output current has reached the set value, the power supply will output constant current. When the current has not reached the set value, it operates in constant voltage mode.
- Overcurrent Auto-stop Mode: When the current has reached the set current, the power supply will stop the output.
- Overcurrent Auto-resumption Mode: When the current has reached the set current, the power supply will stop outputting. Wait for a while and it will automatically resume outputting.
- Buzzer Prompt [?]:
- When the power supply is turned OFF, press and hold the voltage adjustment knob [⚙️] and then press the master power button [⚡].
- Turn the voltage adjustment knob [⚙️] to turn ON/OFF the buzzer [?]. Once done setting, press the voltage adjustment knob [⚙️] to exit the setting interface.
IV. Maintenance & Precautions
- When charging batteries, DO NOT connect the positive [➕] and negative [➖] poles incorrectly.
- It is not recommended for the power supply to output at full power (voltage and current set to maximum) for more than four hours. If more consecutive working hours are needed, please restrict the output usage rate within 60%. Otherwise, over-usage may result in premature failure of the power supply.
