For anyone involved in electronics or laboratory work, a reliable power supply unit is essential. The NANKADF adjustable power supply (0-30V, 0-10A) stands out as a versatile and compact solution.
With a high precision 4-digit display and features like a USB fast charging interface, this power supply offers great value for its price. But does it live up to its promising features? Let’s dive in.
Upon unboxing, the NANKADF power supply immediately impressed with its compact and lightweight design. The digital display is clear and intuitive, making voltage and current adjustments straightforward.
Using the power supply for various tasks, including charging Li-ion cells and testing automotive components, I found it remarkably reliable. However, the noise from the fan and occasional encoder knob issues were minor inconveniences.
High Precision and Compact Size
The DC power supply from NANKADF boasts a high precision 4-digit LED display, capable of showing voltage down to 0.01V and current down to 0.001A. This level of precision is particularly beneficial for intricate electronics work where exact measurements are crucial. Additionally, the power supply’s compact form factor, weighing just 2.47 pounds and measuring 7.48*3.54*5.9 inches, makes it highly portable and easy to fit into tight workspaces.
Digital Adjustment and Output Control
One of the standout features of this power supply is its encoder adjustment mechanism, allowing users to pre-set desired parameters. The OUTPUT button adds an extra layer of control, enabling users to easily turn the power supply on or off. This feature is especially useful when dealing with overcurrent protection (OCP); simply pressing the OUTPUT button can lift the protection state, making the device user-friendly and safe for various applications.
USB Fast Charging Interface
The inclusion of an 18W USB fast charging interface is a thoughtful addition that supports multiple fast charging protocols. This means the power supply can automatically adapt to the device being charged, optimizing the charging process. Not only does this save workspace by eliminating the need for extra chargers, but it also ensures that your electronic devices are powered efficiently.
CC/CV Automatic Switching
The power supply features automatic switching between Constant Voltage (CV) and Constant Current (CC) modes based on the load state. This functionality allows for presetting values using the coding knob, making it highly versatile for different types of electronic work. The built-in Over Voltage Protection (OVP), Over Current Protection (OCP), Short Circuit Protection (SCP), and temperature-controlled heat dissipation further enhance the device’s safety and longevity.
OCP Short Circuit Protection Function
The power supply is equipped with a short circuit protection alarm function, which can be activated by pressing the CURRENT code switch for three seconds. When OCP is enabled, the power supply will stop output and sound an alarm in case of an external load short circuit or overcurrent. This feature is invaluable for protecting your tested products, providing peace of mind during experiments and repairs.
User Reviews Highlight Ease of Use
User feedback consistently praises the power supply for its ease of use. Many reviewers appreciate the intuitive adjustment system and clear digital display. The device’s compact size and lightweight design also receive positive mentions, making it a convenient choice for both professional and hobbyist use. The ability to accurately set and monitor voltage and current levels adds to its appeal.
Noise and Build Quality
While the power supply is generally well-received, some users have noted that the fan can be noisy and has only one speed. Despite this, the fan’s infrequent activation at lower power settings means it won’t be a constant distraction. Additionally, the build quality is often highlighted, with users appreciating the sturdy construction and reliable performance, even under demanding conditions.
Accuracy and Reliability
Users have tested the power supply’s accuracy and found it to be reliable, with voltage accuracy within ±0.1V. This makes it suitable for precise tasks such as charging Li-ion cells, where accuracy is crucial. The device’s consistent performance in various applications, from automotive components to lighting, underscores its versatility and dependability.
Comprehensive Safety Features
Safety is a critical aspect of any power supply, and this model doesn’t disappoint. The inclusion of multiple protection mechanisms, such as OVP, OCP, SCP, and temperature control, ensures that both the power supply and the connected devices are safeguarded against potential hazards. These features collectively work to extend the device’s service life and provide a secure operating environment.
Additional Convenience Features
Small details, such as the well-fitting mains plug and flexible mains cable, contribute to the overall user experience. Reviewers also appreciate the inclusion of a fast charging USB port, which adds to the device’s versatility. The supplied DC leads and screw terminals, although basic, are functional and meet most users’ needs without requiring immediate replacement.
Potential Areas for Improvement
Despite its many strengths, there are a few areas where the power supply could be improved. Some users have pointed out the need for variable speed control for the fan to reduce noise. Others have mentioned the presence of switching noise, which could be mitigated with additional internal suppression components. These minor issues, however, do not significantly detract from the overall positive user experience.
Pros:
- High precision 4-digit LED display
- Compact and lightweight design
- USB fast charging interface
Cons:
- Noisy fan with only one speed
- Dim CV/CC/OUT indicators
- Switching noise on output
Conclusion
Overall, the NANKADF adjustable power supply is a solid investment for anyone needing a versatile and reliable bench power supply. Its compact size and precision make it a valuable tool in any lab or workshop.
Despite a few minor flaws, the unit’s performance and features, like the USB fast charging interface and CC/CV automatic switching, make it highly recommended for both hobbyists and professionals.
