Warnings:
- Adjustment Delay: Turn on the DC power supply, set the required voltage/current, then connect the load.
- Setting Current: Adjust voltage below 3V before connecting output wires to prevent sparks; then set the desired current.
- Power Off When Not in Use: Disconnect the power supply when not in use.
- Cleaning: Remove the power cord before cleaning. Avoid using solvents with hydrocarbons, chlorides, or abrasives.
- Voltage Decrease: Voltage will gradually decrease when turned off due to capacitor discharge.
Questions & Answers:
- Why can't the current be adjusted? Ensure a load is connected and the voltage setting is not at 0.
- Why isn't the cooling fan working? The fan activates at 50°C (122°F) due to a built-in temperature control sensor.
- Input Voltage and Plug Type Selection: Products and plugs are selected based on your country. Contact us for special requirements.
- Scratches on the screen? The screen has a protective film that can be peeled off.
