Jesverty DC Power Supply Variable

Bottom line: The Jesverty DC Power Supply Variable: Full 0-30V 0-10A range with separate coarse and fine knobs for exact setpoints; main trade-off: bundled test leads are a giveaway; heavy current use needs better-rated leads.

Pros & Cons

Pros

  • ✓ Full 0-30V 0-10A range with separate coarse and fine knobs for exact setpoints
  • ✓ 4-digit LED reads V, A, and W live at 0.01V / 0.001A / 0.1W resolution
  • ✓ Auto C.V./C.C. switching follows load changes without manual intervention
  • ✓ 5V/2A USB port runs dev boards and phones off the front panel
  • ✓ Compact 7.1 x 3.35 x 6.1 in, 2.5 lb chassis frees up bench space

Cons

  • ✗ Bundled test leads are a giveaway; heavy current use needs better-rated leads
  • ✗ Temperature-regulated fan means audible noise on a quiet bench under load
  • ✗ Switching topology, not linear, so it is noisier electrically than a linear supply
  • ✗ Power cord and AC input setting vary by shipping destination

Manufacturer description

The Jesverty SPS-3010 is a variable bench power supply that covers 0-30V and 0-10A with coarse and fine adjustment knobs, so you can dial in a rail precisely instead of settling for the nearest click. A big 4-digit LED display reports voltage, current, and wattage in real time at 0.01V, 0.001A, and 0.1W resolution, which means you are reading actual output rather than guessing from a knob position. Auto C.V./C.C. switching handles changing loads on its own: the voltage and current values you set define the crossover point where the unit flips between constant-voltage and constant-current…

SpecPicks Verdict

SpecPicks scored Jesverty DC Power Supply Variable using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies category. Jesverty's power supplies lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for power supplies of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.

Frequently Asked Questions

What voltage and current range does the SPS-3010 cover?

It is adjustable from 0 to 30V and 0 to 10A, with coarse and fine adjustment knobs on both so you can land on an exact setpoint rather than a rough one.

How precise is the display readout?

The 4-digit LED shows live output with resolution down to 0.01V, 0.001A, and 0.1W, and it reports voltage, current, and calculated wattage at the same time.

Does it switch between constant voltage and constant current automatically?

Yes. It moves between C.V. and C.C. modes on its own as the load changes. The V and A values you set are the crossover point where the mode flips.

Can I charge or power USB devices from it?

There is a dedicated 5V/2A USB port, so you can run a dev board or phone from it while the main 0-30V terminals stay free for your project.

What comes in the box, and what protections does it have?

You get the SPS unit, a power cord, a set of test leads, and an instruction manual. Protection includes short-circuit and overload cutoff, a grounding terminal, and a temperature-regulated fan.
