Features

  • Upgraded DC Power Supply: The upgraded DC power supply integrates various advanced functions. For example, precise coding knobs, USB and type-c fast charge, OCP short circuit alerts, high-definition four-digit display and multiple security protection Settings
  • Coarse and Fine Coding Knob: Unlike other coding knobs, this bench power supply is equipped with coarse and fine tuning coding knobs, the coarse tuning knob sets the value before the decimal point, and the fine tuning sets the number after the decimal point. The combination of the two knobs greatly improves efficiency
  • USB and Type-C Charging Port: One of the major advantages of our variable power supply over other variable power supplies is the addition of the TYPE-C fast charging port, which is different from the normal USB charging port and has a 5V/3.6A output for quickly charging your cell phone or other device, or for charging a device to be repaired
  • Short Circuit Alarm: Safety always comes first. When the load equipment is short-circuited, the adjustable power supply will automatically stop the output and emit a buzzer to remind the user. Not only that, the adjustable power supply also has the functions of grounding wire, leakage protection, overheating protection, voltage overload protection and power overload protection
  • Wide Applications: The adjustable dc power supply features an intelligent temperature-controlled fan and heat sink for excellent heat dissipation and is especially suitable for laboratory, electronic repair DIY, communication equipment maintenance, products line, scientific research and teaching units
  • Packaging: 1 x variable dc power supply, 1 x output power cord, 1 x input power cord, 1 x user manual. Tip: If you want to turn off the key beep, press and hold the voltage knob for a few seconds until you hear a beep, then the key beep will turn off
  • This DC power supply has been upgraded with automatic voltage detection technology, intelligently adapting to 110V and 220V 10% AC inputs without manual switching. Please note: The voltage toggle switch (115V/230V) has been removed from the rear panel as it is no longer required.

Description

WANPTEK POWER is a professional manufacturer of DC power supply. We have more than ten years of experience in manufacturing and research and development in the instrumentation industry. We are committed to providing our customers with complete power supply solutions. We will continue to provide you with the best quality products. We hope that our variable power supply can make your life easy and beautiful. WANPTEK DC power supply comes in five specifications: 0-30V 0-5A | 0-30V 0-10A | 0-60V 0-5A | 0-120V 0-3A | 0-160V 0-2A Press and hold the Voltage Coarse knob to turn off the key beep. I do like that you can mute the beeping. The dc power supply also makes a short beep for each increment. If you want it mute, just need to press and hold the Voltage Coarse knob to turn off the beep. The values are clearly displayed even in dimly lit environments. This is exactly what I've been looking for in a bench power supply. It has a bright, large display,which is very readable. It's easy to control voltage or constant current. Happy to finally have a reliable variable power supply. I like about having this dc power supply is that it comes with USB-A and USB-C charging ports. With the USB C port supporting PD charging up to 20W. When a short circuit occurs in the dc power supply or load, the adjustable power supply will automatically shut down the output and sound an alarm. This upgraded dc power supply automatically switches input voltage based on your location. If you are in a region using 110V, it will adjust to 115V. This is a small lab power supply with a lot of power. There are course and fine knobs that allow you to fine-tune the right voltage and amperage. How do I precisely adjust voltage and current with the rotary knobs? This adjustable DC power supply features four independent control knobs. Use the coarse knobs for quick, large adjustments and the fine knobs for micro-tuning voltage and current to achieve exact values effortlessly on the 4-digit LED display. How does the short-circuit alarm protection work on this unit? Equipped with an active OCP protection system. When OCP mode is enabled, the unit instantly stops power output and sounds a buzzer alarm if a short circuit or overcurrent occurs, safeguarding your sensitive load. Can I use this power supply to charge phones or auxiliary USB devices? Yes! Built as a versatile bench power supply, it includes built-in USB-A and USB-C charging ports directly on the front panel. You can easily charge your smartphones, tablets, or power secondary USB gadgets right at your electronics repair workbench. Is this unit powerful and precise enough for professional laboratory and repair tasks? Absolutely. Delivering a stable 30V 10A 300W continuous output with high accuracy, this variable power supply is specifically engineered for laboratory experiments, PCB circuit board repair, aging tests, and DIY electronic prototyping. Does this power supply automatically switch between Constant Voltage and Constant Current modes? Yes. Functioning as a high-performance regulated DC power supply, it features automatic C.V/C.C mode switching. The bright C.V (Green) or C.C (Red) indicator on the front panel clearly shows your circuit's current operating status in real time. WDPS3010U WEPS3210 WGA3010H WTPS-C3010H WTPS-C3010B

  • Very Nice Bench Power Supply
Size: 0-30V 0-10A Color: Black
This is a very nice bench power supply for the price. It offers plenty of voltage/current/power range, has all the expected CV/CC functions (or OCP cutoff, user selectable), voltage and current limits are each set via two knobs (coarse and fine) and a push of the knob changes the digit that is being adjusted so coarse to very fine adjustment is possible, it has both USB A and C charge outputs, the display shows voltage/current/power of the adjustable power supply simultaneously, and is in a very light and compact yet very sturdy housing. ... show more

  • I deserved this !
Size: 0-30V 0-10A Color: Black
At work and while training ( would-be rocket scientist ), I always had lab power supplies at arm length. There is nothing better for testing, analyzing, protecting developmental or repairable devices than a controlled, adjustable power supply. You have probably read and understand the specs. Being able to limit maximum current or set the power supply into a "constant current" mode is very useful. Especially when working with LED lighting and devices which are current-driven rather than voltage driven. Sometimes I'd wish for more than 30 Volts ( like 48 or so ) but that isn't often. 30V / 10A covers 99% of anything on my bench. The rest might get haywired from 12V / 7AH UPS batteries or jumpered PC power supplies. This is a nice size, has bright clear displays, serious binding posts, front panel USP charge ports. Small and light enough to take with me, important enough to be right next to the 'ol oscilloscope and bucket of test leads. It is a great value and easy to use. The point is that I wanted a current-technology adjustable power supply for a long time. Can't explain the hesitation in buying myself something "good" that I enjoy. Simple pleasures and better thinking. Also fewer fried circuits. So this isn't a technical review but my opportunity to say that I bought something that I like and that I am very satisfied with it. Amen. ... show more

  • Fantastic MultiPurpose use
Size: 0-30V 0-10A Color: Black
This power supply is amazing. Myself and several of my team mates on our car audio team use these to charge our lithium banks in our cars because you can set the charge rate and voltage you want to charge to and it works like a charm. They're so easy to adjust and the voltage controls are amazing. They don't weigh much so they're easy to transport ... show more

  • Great Voltage and Amperage Control…
Size: 0-30V 0-10A Color: Black
I use this DC variable power supply to run a bilge fan to remove odors from a sump pump cavity. I don’t need to run the 12VDC fan at full speed so having the ability to vary power output to around 5VDC lowers fan noise and prolongs fan life. This is a great little unit, very reliable!

  • Would recommend for sure
Size: 0-30V 0-10A Color: Black
I would give it 5 stars but time will tell. I immediately hooked the unit up to a multi meter to test it. Its not perfect and has some variance, but it gets the job done. Within an hour I revived 2 dewalt 20v batteries and tested some questionable led strips

  • Excellent Power Supply
Size: 0-30V 0-10A Color: Black
Excellent power supply. You have to get used to the adjustments because it's a complete digital power supply. The voltage adjustment is for the integer part and the fine in for the decimal part. The voltage is very exact.
