Jesverty Adjustable DC Bench Power Supply 0–30V 0–10A SPS-3010 — 4-Digit LED, 5V/2A USB, CV/CC Protection

Jesverty SPS-3010 is a compact, adjustable DC bench power supply delivering 0–30V and 0–10A with a high-precision 4-digit LED readout and a 5V/2A USB port.

Designed for electronics hobbyists, lab benches, and repair work, the Jesverty SPS-3010 packs accurate voltage and current control into a lightweight housing. The unit reports real-time volts, amps, and watts on a fine-resolution display, supports automatic constant-voltage/constant-current switching, and includes coarse and fine adjustment knobs for rapid setup and precise trimming. Built-in protections and a small footprint make it suitable for bench testing, prototyping, and educational use.

How accurate is the display and what measurements can I see?

The SPS-3010 uses a bright 4-digit LED panel that shows output voltage, output current, and calculated power simultaneously. Resolution reaches 0.01V for voltage, 0.001A for current, and 0.1W for power so you can monitor small changes while tuning circuits.

• 4-digit LED readout for V/A/W in real time
• Voltage resolution: 0.01V
• Current resolution: 0.001A
• Power resolution: 0.1W

Will it protect my components during testing?

The unit includes multiple safety features to protect both your device under test and the power supply itself. It supports automatic switching between constant-voltage (CV) and constant-current (CC) modes so the output adapts when the load changes, and it has protections against short circuits and overloads.

• Auto CV/CC mode switching at user-set crossover points
• Short-circuit and overload protection to prevent damage
• Thermal control with a temperature-regulated fan
• Grounding terminal for safer bench operation

How compact and portable is the SPS-3010 for workshop use?

The SPS series is engineered to occupy minimal bench space while delivering useful output power. At roughly 7.1 x 3.35 x 6.1 inches and around 2.5 pounds, it is easy to move or store when your workspace is limited.

• Small footprint fits tight workbenches and hobby stations
• Lightweight for transport between projects or classrooms
• Stable rubber feet and clear front-panel layout for easy access

What accessories and support come with the supply?

The package includes the main SPS unit plus basic accessories so you can get started quickly. Jesverty provides user documentation and customer support; note that supplied test leads are convenience extras and may not suit sustained high-current use.

• Included: SPS unit, power cord (region-specific), basic test leads, instruction manual
• 5V/2A USB port for powering small USB devices or charging
• Manufacturer technical support and contact information in the manual
• Recommendation to use higher-capacity test leads for long-term high-current projects

Who is this for: The Jesverty SPS-3010 is a practical choice for electronics enthusiasts, students, makers, and engineers who need reliable, adjustable DC power with clear readouts in a compact package. It serves well for bench experiments, PCB testing, component characterization, and small repairs where precise voltage and current control plus protective measures are important. If you require laboratory-grade automation or multi-channel outputs, consider higher-end series models; for single-channel bench tasks and portable testing, the SPS-3010 balances accuracy, safety, and convenience.
