Jesverty SPS-3010 Variable DC Power Supply Review – 0-30V, 0-10A Adjustable Bench Power Supply

The Jesverty SPS-3010 is a compact variable DC bench power supply designed for electronics testing, prototyping, repairs, laboratory projects, and hobbyist work. With an adjustable 0–30V voltage range and 0–10A current range, a bright 4-digit LED display, automatic Constant Voltage/Constant Current operation, and multiple protection features, it provides useful control for a wide variety of electronics projects.

⭐ Overall Review

The Jesverty SPS-3010 is a practical choice for users who need an adjustable DC power source without taking up a large amount of bench space. Its compact approximately 7.1 × 3.35 × 6.1-inch body and roughly 2.5-pound weight make it relatively easy to position or move around a workbench.

One of its strongest features is the 4-digit LED display, which provides real-time readings of voltage, current, and power. With display resolution up to 0.01V, 0.001A, and 0.1W, it gives users detailed information while testing or powering circuits.

The power supply also automatically switches between Constant Voltage (CV) and Constant Current (CC) modes as the load changes. This makes it useful for projects where maintaining controlled voltage or current is important.

🔥 Key Features

⚡ Adjustable 0–30V & 0–10A Output

The SPS-3010 provides adjustable output from 0 to 30 volts and 0 to 10 amps, giving electronics enthusiasts plenty of flexibility for different testing and development applications.

📊 High-Precision 4-Digit LED Display

The bright LED display provides real-time measurements of:

• Voltage (V)

• Current (A)

• Power (W)

The display resolution reaches 0.01V, 0.001A, and 0.1W, allowing users to monitor output with useful precision.

🔄 Automatic CV & CC Modes

The power supply automatically transitions between Constant Voltage (CV) and Constant Current (CC) operation based on the connected load. This makes it easier to maintain the desired operating conditions when circuit requirements change.

🔧 Coarse & Fine Adjustment

Separate coarse and fine adjustment controls make it easier to quickly reach a desired output and then make more precise changes.

🔌 5V/2A USB Port

A built-in 5V/2A USB port provides an additional convenient power option for compatible USB-powered devices and projects.

🛡️ Multiple Protection Features

The SPS-3010 includes several safety-oriented features, including:

• Short-circuit protection

• Overload protection

• Grounding terminal

• Temperature-regulated cooling fan

These features are designed to provide more reliable operation and help protect the unit during demanding applications.

🧪 Performance & Usability Review

For general electronics work, the SPS-3010 provides a useful combination of adjustable output, detailed monitoring, and compact construction.

The coarse/fine controls are particularly helpful when precise voltage or current adjustments are needed. The real-time power display also gives users an immediate view of how much power the connected load is consuming.

The automatic CV/CC switching is another practical feature. Rather than requiring manual mode selection every time the load changes, the unit responds automatically based on the configured limits and connected circuit.

🛡️ Safety & Reliability

The included protection functions make the SPS-3010 more suitable for everyday bench work. Short-circuit and overload protection can help reduce the risk of damage when something goes wrong during testing.

However, users should still follow proper electrical safety practices and select suitable cables and accessories for the required current. Jesverty specifically notes that the included test leads are not intended as the ideal solution for long-term high-current applications.

⭐ Final Verdict

The Jesverty SPS-3010 0–30V 0–10A Variable DC Power Supply offers a strong feature set for electronics hobbyists, students, repair technicians, and DIY builders. Its adjustable voltage and current output, detailed 4-digit display, automatic CV/CC modes, USB port, and protection features make it a versatile addition to an electronics workbench.

Its compact size is another major advantage for users with limited workspace. While advanced professionals may prefer a more sophisticated laboratory power supply, the SPS-3010 provides a practical balance of control, portability, functionality, and value for general-purpose electronics work.

⭐ Rating: 4.5

Best For: Electronics testing, DIY projects, circuit prototyping, repairs, students, hobbyists, and home laboratories.

Bottom Line: If you need a compact adjustable bench power supply with 0–30V, up to 10A output, precise digital monitoring, CV/CC operation, and built-in protection, the Jesverty SPS-3010 is a versatile option worth considering.
