A reliable DC bench power supply is essential for electronics enthusiasts, students, lab technicians, and engineers alike. Whether you’re testing components, powering circuits, charging batteries, or calibrating devices, a power supply that offers stability, precision, and user-friendly controls is indispensable.
The Jesverty SPS-6005 is a variable, regulated switching DC power supply with a wide voltage and current range—up to 60 volts and 5 amps. Its standout features include high precision with a 4-digit LED display, a dedicated 5V/2A USB output, and coarse/fine adjustment knobs. This model aims to offer flexibility, portability, and performance at a competitive price.
This article dives into the design, performance, key features, and real-world use cases of the SPS-6005, explaining why it’s a worthy addition to any electronics workstation.
1. Overview and Core Specifications
Let’s begin with the core technical specifications of the Jesverty SPS-6005:
- Output Voltage Range: 0 – 60V DC
- Output Current Range: 0 – 5A
- Voltage Regulation: <0.1% + 5mV
- Current Regulation: <0.1% + 10mA
- Display: High-precision 4-digit LED display for voltage and current
- USB Port: 5V, 2A output for charging or powering USB devices
- Cooling: Intelligent temperature-controlled fan with multiple ventilation slits
- Weight: Approx. 2.2 kg
- Form Factor: Compact, portable bench-style case
This regulated power supply uses switching technology (as opposed to linear), which provides better efficiency, a lighter build, and lower heat generation. It’s ideal for medium-duty tasks and fits well in laboratories, DIY setups, repair shops, and classrooms.
2. Build Quality and Design
Despite being compact and relatively lightweight, the SPS-6005 feels robust and well-built. Its metal enclosure adds to its durability while helping with passive heat dissipation. The design is straightforward, with clearly labeled output terminals, a bright display, and intuitive knobs and buttons.
The front panel includes:
- Two banana plug terminals for positive and negative DC output
- A ground terminal
- A bright 4-digit LED display (independent readouts for voltage and current)
- USB port (5V/2A) for auxiliary power
- Power switch
- Voltage and current adjustment knobs—both coarse and fine
The inclusion of both coarse and fine adjustments is a big plus, allowing you to dial in precise values efficiently. For instance, coarse knobs quickly get you close to the target value, while the fine knobs help zero in with greater accuracy, essential when working with sensitive electronics.
3. Performance and Accuracy
The Jesverty SPS-6005 uses switch-mode power supply (SMPS) technology, which enables it to deliver efficient and stable power over a wide voltage and current range. While SMPS units sometimes introduce minor ripple or noise compared to linear power supplies, the SPS-6005 does a great job at keeping these to a minimum, typically below 100mV peak-to-peak.
Key performance metrics:
- Voltage Stability: The voltage output remains impressively consistent under varying loads, with minimal fluctuation.
- Current Limiting: You can set the maximum current draw, which is useful for protecting components during experiments or tests.
- Load Regulation: Maintains voltage accuracy even as load changes occur.
- Line Regulation: With varying AC input, the output remains stable.
The 4-digit display provides readings accurate to 10mV and 1mA levels—making it highly usable for precision work.
4. USB Output Port – A Useful Bonus
The 5V 2A USB output is a nice addition. It’s independent from the main adjustable output, meaning you can simultaneously use it to power USB devices such as:
- Arduino boards
- Raspberry Pi modules
- Smartphones
- Wireless adapters
- LED strips
- Test gadgets
This means one device can serve multiple testing functions—cutting down clutter on the bench.
5. Safety and Protection Features
Safety is a priority with any lab power supply, and the Jesverty SPS-6005 includes several key features to protect both the device and your components:
- Overvoltage Protection (OVP)
- Overcurrent Protection (OCP)
- Overtemperature Protection (OTP)
- Short Circuit Protection
- Current Limiting Mode
The intelligent temperature-controlled fan only engages when needed, minimizing noise during light use. The fan ramps up as the internal temperature rises—particularly during high voltage or high current sessions—preventing overheating without contributing unnecessary noise.
6. Use Cases and Applications
The versatility of this power supply makes it suitable for a broad range of tasks. Some real-world applications include:
Electronics Repair and Debugging
- Powering and testing consumer electronics
- Debugging circuit boards
- Replacing battery circuits in old gadgets for testing
Electronics Prototyping
- Perfect for breadboarding and powering microcontroller circuits (Arduino, ESP32, etc.)
- Ideal for analog and digital circuit experimentation
- Helps simulate varying voltages for voltage tolerance tests
Battery Charging and Testing
- Safe for charging lithium-ion, LiPo, and other batteries (with the proper charger circuitry)
- Can be used to test charge/discharge cycles and performance of battery packs
Educational and Lab Use
- Excellent for physics and electronics labs in schools, colleges, and vocational centers
- Great for teaching power supply principles, Ohm’s Law, and circuit behavior
Amateur Radio and Audio Equipment
- Used to power receivers, amplifiers, and custom-built radio rigs
7. Advantages
- Wide Range (0–60V, 0–5A): Covers most needs for hobbyist and intermediate professional work.
- Precision Controls: Coarse and fine adjustment knobs make tuning voltage and current easy and accurate.
- High-Visibility Display: The 4-digit LED is crisp, readable from multiple angles, and very responsive.
- USB Output: Simultaneously power or charge USB-compatible devices.
- Quiet and Efficient: The SMPS design ensures high efficiency and reduced heat; fan stays quiet unless needed.
- Safety Protections: Comprehensive built-in safety features protect both the user and connected devices.
8. Limitations and Considerations
While the SPS-6005 performs well in many regards, it’s not without some minor drawbacks:
- Switching vs. Linear: As a switching supply, it may introduce slight noise into sensitive analog circuits—though this is rarely a major issue at this price point.
- No Remote Sense: There are no separate sense terminals for compensating voltage drop across wires.
- Single Output Channel: Some more expensive lab power supplies offer dual or triple outputs, which this lacks.
- Plastic Knobs: Though functional, the knobs are plastic and could feel a little cheap compared to premium models.
9. Final Verdict
The Jesverty SPS-6005 delivers outstanding value-for-money as a versatile, compact, and precise bench power supply. It’s ideal for students, hobbyists, technicians, and even professionals who don’t need ultra-high-end equipment but still value reliability, precision, and smart design.
If you’re in the market for a bench power supply that offers wide voltage range, current limiting, accurate displays, and extra usability via USB, this unit checks all the boxes—especially at its mid-tier price range.
Summary: Is It Worth It?
Absolutely. The Jesverty SPS-6005 packs a lot into a small footprint:
- Reliable voltage and current output
