The Encoder Adjustable Lab Power Supply delivers stabilized DC voltage and precise current regulation for professional electronics repair, laboratory testing, and DIY projects. Designed for technicians and makers alike, this compact power source combines rapid encoder tuning with automatic constant voltage and current modes.

Encoder Control System: Dedicated fine and coarse knobs enable seamless continuous adjustment of output voltage and current up to 10A.
High-Precision Digital Display: Dual-line LED readouts show real-time voltage (0.01V resolution) and current (0.001A resolution) for rapid monitoring.
Comprehensive Protection Circuits: Built-in OVP, OCP, OTP, short-circuit, and leakage safeguards prevent component damage during intensive bench work.
Quiet Cooling Technology: Thermal sensors engage the fan only above 50°C, minimizing acoustic interference during delicate troubleshooting.
Compact Form Factor: Weighing just 2.6 pounds with a rugged anodized shell, it fits easily into any service cart or engineering station.

This Encoder Adjustable Lab Power Supply streamlines diagnostic workflows by eliminating guesswork during circuit tracing and battery charging. Automatic CV/CC switching maintains stable output without manual recalibration, while multi-region plug compatibility ensures immediate deployment in labs, repair shops, and educational facilities. This Encoder Adjustable Lab Power Supply solves common bench headaches by delivering parameter visibility, preventing accidental stress on sensitive components, and saving valuable workspace floor area compared to older transformer models.

5 Frequently Asked Questions:

How does the encoder adjustment improve precision?: Separate fine and coarse dials allow millivolt and milliamp-level corrections without overshooting target values.
Is the cooling fan loud during operation?: No. The thermal controller keeps the fan dormant below 50°C to reduce noise and conserve energy.
Can this unit safely charge lithium batteries?: Yes. The stable constant-current mode and integrated overcurrent protection handle LiFePO4 and lead-acid restoration reliably.
What certifications guarantee its safety?: The device meets CE, FCC, and EU LVD electrical standards for commercial and domestic use.
Does it support different grid voltages?: Yes. Dual input compatibility accepts AC 115V or 230V at 50Hz or 60Hz.

The power supply is of excellent quality and works perfectly. Delivery to Kyiv took two months. I recommend the product for its quality.

It took a long time to arrive, but it was packaged perfectly. No defects were found during testing, the contents are as shown in the photo. Definitely a must-have, but only worth buying with a discount.

Excellent. Good construction, nice finishes, I should have bought it a long time ago.

Great! It arrived very quickly. Flawless product, flawless packaging. It works perfectly. It contains high-quality ingredients. Beautiful and flawless welds. The Current and Voltage regulation works perfectly. Unfortunately, its level of inaccuracy is much higher compared to the TPS series. It continuously drops from a low voltage of 0.2V to a maximum of 32V, with a range of 30mV to 150mV. Compared to the displayed value. Moreover, it increases exponentially. My other TPS series Wanptek power supply supplies a total of 10mV across the entire voltage range.
Therefore, this is not a "lab tap", just a regulated power supply.

The product is really good quality. It is indeed small but the quality is really good. I am very satisfied with this purchase and i will buy from them again

Great, I like everything, but the delivery was very long, about a month and a half due to some drone-related policy. The fan doesn't spin immediately, maybe it will start under heavy load. There is a burning smell if you sniff the case itself, but overall I haven't disassembled it, everything works, I recommend it. By the way, the seller responds if you ask him questions.

Everything was fine. The delivery was fast. It arrived well packaged. The quality is good. I am satisfied.

Arrived fast and working perfectly ok.

Nice product

Great product, works as intended. Fast shipping. Arrived in 3 days

The product arrived with a damaged power cable; both pins on the plug were broken.

The shipping was quite fast. The product itself is small but quite versatile and comfortable to use. I am very happy with the purchase.

The truth! I was surprised, the tension as you can see is not very variable, almost exact! and the semi-premium construction materials.

I liked it a lot. It exceeded my expectations.

It was well packaged. Everything seems to be working. Convenient encoder control. Shows accurately. In the photo is a 12 V, 21 W car bulb.

VERY GOOD SOURCE, STOCK IN BRAZIL, SHIPPING BY JT EXPRESS SUPER FAST
I RECOMMEND
I BOUGHT IT FOR A SECONDARY WORKBENCH, THE 10A HAS ALREADY JUSTIFIED THE AMOUNT PAID, 2 SERVICES I DID USING IT PAID FOR ITSELF.

WAMPTEK laboratory power supply model GC3010L + EU power cable + manual + test cable with alligator clips, well received, delayed but in good condition.

This is the second one I'm buying because I'm so satisfied with the first one. 👍🏻 🙂

This second power supply works as well as the first one. 👍🏻 🙂 👌🏻 🙂

What's really good is the accurate prediction of voltage and current values. 💪🏻 💪🏻
No need to take out the multimeter anymore, the indications given by the power supply are provided and precise.

It is a super lab power supply.

I love the digital adjustment, with a minimum step of 10mV for voltage and 1mA for current. 👍🏻
It keeps its promises of 320W.

You can buy from WAMPTEK with your eyes closed.

I RECOMMEND 10,000%.

Damaged packaging :(

Got it quickly, packaged good, works 🥳 The voltage reads a bit off but not critical

The power supply is decent. This is not the first time I've bought from this store. The seller is responsible and reliable. I recommend it.
