Unlock New Capabilities (Project Evolution)

     If you have been relying on fixed 5V/12V "wall wart" adapters or cheap         XL6009 buck converters, the KA3005DS is your next major upgrade.

• Past Projects: Basic breadboarding with fixed voltage rails.
• Feature Upgrade: This unit unlocks Current Limiting. You can now set a 50mA limit while powering a new prototype—if there’s a short, the supply cuts off, saving your components.
• Effort Level: Intermediate (Requires basic understanding of V/I relationship).

ACCESSORIES / PACKAGE INCLUDED

• 1 x Korad KA3005DS Precision Programmable DC Power Supply

• 1 x AC Power Input Cable

• 1 x High-quality Banana-to-Alligator clip leads

• 1 x User Manual

FREQUENTLY ASKED QUESTIONS (FAQ)

1. How do I set a current limit on the KA3005DS?
   Press the 'Current' button, use the rotary dial to set the limit, and ensure OCP is active.

    

2. Is the KA3005DS a linear or switching power supply?
   It is a high-quality transformer-based linear power supply for low noise.

    

3. Does it come with a calibration certificate?
   It is factory calibrated; Probots performs an additional lab verification check.

    

4. Can I use this to charge a 12V Lead Acid battery?
   Yes, by setting the correct float voltage and current limit.

    

5. What is the difference between KA3005D and KA3005DS?
   The 'S' version usually denotes an upgraded control chipset for better stability.

    

6. Is the fan always on?
   No, the fan is temperature-controlled and only kicks in under heavy load.

    

7. How do I save a preset to memory?
   Adjust your settings, then long-press the desired memory button (M1-M5).

    

8. Can I connect two units in series for 60V?
   Yes, but ensure the current limits are matched.

    

9. What is the ripple voltage of this unit?
   It is ≤2mVrms, making it suitable for sensitive RF circuits.

    

10. Does it support USB PC connectivity?
    This specific model is the standard programmable version without the USB interface.

     

11. How do I lock the front panel?
    Long-press the 'Lock' button to prevent accidental setting changes during long tests.

     

12. Can it handle a 5A load continuously?
    Yes, the heavy-duty transformer and fan allow for sustained 5A output.

     

13.  What happens if I short the terminals?
    If CC mode or OCP is set, the unit will safely limit or cut the current.

     

14. Is the output isolated?
    Yes, the DC output is isolated from the AC input.

     

15. Does it remember settings after power off?
    Yes, it retains the last used settings and memory presets.

     

16. Can I use this for anodizing?
    Yes, the constant current (CC) mode is ideal for anodizing processes.

     

17. What is the resolution of the display?
    It features a 10mV and 1mA resolution display.

     

18. Is the power cord included?
    Yes, a standard Indian 3-pin power cord is included.

     

19. Can I use it to power a Raspberry Pi?
    Absolutely, set it to 5.1V and 3A for optimal Pi 4 performance.

     

20. Is there a warranty?
    Yes, standard Probots warranty applies to all Korad units.
