## Before you buy

- The listing details are inconsistent or unconfirmed: the title claims a 0–30V, 0–30A range and 900W, while the technical details provide 30 volts DC and 30 A without a range, and the listed 110-volt AC input is malformed. The feature text gives approximate weight of 6.6 lb while the details list 3.62 kg, and shipment-specific AC input settings and power cords may vary. Confirm the required input configuration and output range for your intended use.

## A good fit for

- Electronics repair and DIY work needing an adjustable benchtop DC supply.
- Lab, educational, or manufacturing-test setups where the claimed output-control button and OVP/OCP are useful.
- Workbenches where compact listed dimensions are a consideration.

## Less suited to

- Buyers who need a confirmed AC input configuration without checking shipment-specific settings.
- Users who require verified output performance figures or a clearly specified complete voltage range before selecting a supply.

## Customer feedback

Aggregate ratings skew strongly positive, with a small number of ratings overall and a small two-star share. This provides only a broad satisfaction signal, not specific evidence about output accuracy, protection behavior, or long-term reliability. Buyers should base those requirements on the listed specifications and confirm the unresolved input details.

## Frequently asked questions

### What controls does the Jesverty SPS-3030H list?
The listing describes an encoder adjustment knob with 0.01V/0.01A setting resolution and a separate output on/off button.
### Which protections are specified?
The listing specifies over-voltage protection \(OVP\) and over-current protection \(OCP\), and also describes a temperature-regulated cooling fan.
### Does the listing clearly establish the input configuration?
No. The technical details contain a malformed 110-volt AC input value, and the listing says AC input settings and power cords vary by factory shipment. Confirm the configuration for the selected listing.
### What is stated about the included items?
The listing’s package details name one SPS-H unit, one power cord, and one instruction manual. The feature text describes the unit as SPS-H/HP, so check the selected listing and shipment configuration.
