The MYJG series is simple to unplug and replace. If you're doing more extensive rewiring, a schematic would be helpful (though it wasn’t included in the box). I’ve heard complaints about the display being cracked, but everything I received was in perfect condition.

I purchased this power supply, the RDC6445S controller, and the Cloudray RECI C02 laser tube. I had some initial setup issues, but Cloudray's support team helped me resolve them quickly. The issue turned out to be a faulty laser tube, and they replaced it promptly. Their customer service was great, and the product is working perfectly now.

Description
Laser Power Supply, Efficient & Stable Power Supply
Our laser power supply is compatible with most of the laser tubes on the market, with durable quality and triple protection (constant current protection, open circuit protection, corrosion protection) to meet the needs of multiple crafting industries.
The laser tube must be cooled with water when working, and at the same time, do not turn on the high-voltage output, and ensure that the positive and negative terminals of the high-voltage output must be correctly connected with the positive and negative terminals of the laser.
The interior of power supply is designed to release the remaining charge when the power is turned off, which usually takes two seconds. For safeguard reasons, be careful of electric shock.
Our laser power supply can process to complete the laser engraving of acrylic, fiber fabric, bicolor plate, rubber and other materials, you can choose the engraving material you need.
In addition to laser power supply we also have engraving machine, laser tube for you to buy, no need to repeatedly compare the selection, the whole set with the purchase allows you to instantly enjoy the ultimate engraving experience.

Get Stable Power for Engraving with VEVOR Laser Power Supply

The VEVOR CO2 Laser Power Supply combines compatibility, durability, and safety in one unit. It handles 40W laser tubes and is compatible with several brands. Ports are clearly marked, making it easy to set up, even for the less experienced. 


With its internal fan and other safety capabilities, the system does not overheat, and its temperature remains controlled even after prolonged use. The unit has been proven to work efficiently, with minimal downtime, and consistently delivers clean and precise outcomes. Compatible with workshops and businesses that prioritize safety, this unit is reliable and durable.


Compatible with 40W Laser Tubes and Multi-Brand Machines

The VEVOR CO2 laser power supply is designed with precision for 40W laser tubes, ensuring smooth performance across different engraver and cutter brands. The ports, along with their respective labels, allow for easy setup and help prevent mistakes. Even non-professionals or beginners can follow procedures and safely complete installations without having a technical background. This saves time and effort because the device is plug-and-play. 


All standard 40W laser tubes are matched perfectly to eliminate voltage mismatches and ensure stable output. The VEVOR power supply is a smart choice for diverse setups because it provides flexibility for workshops with varied equipment.


Effortless Connection with the VEVOR Laser Power Supply

The VEVOR CO2 laser power supply offers a user-friendly design. Every port is distinctly marked, allowing users to follow the wiring process methodically. The design minimizes the risk of damaging the laser tube or engraver due to faulty wiring. 


The simplicity of the design reduces the setup time, which in turn reduces downtime and increases productivity. As time is precious in busy workshop settings, users can finalize the process rapidly and resume production. 


Advanced Cooling for Heat Dissipation and Longer Life

Overheating is a common issue with power supplies, but VEVOR manages to resolve this with a super-efficient cooling fan. The fan circulates air at high speed inside the unit’s components during high-performance sessions, maintaining safe operating temperatures. The ability to prevent heat buildup enables the system to produce a stable output, thereby reducing the likelihood of malfunctions and sudden shutdowns. 


The power supply and the connected laser tube also tend to last longer due to the consistent cooling. Less strain on the circuits and wiring lowers the chances of repairs, providing longer-lasting performance. Productivity is enhanced, and maintenance costs tend to decrease over time.


Proven Performance with Speed and Efficiency

Reliability is supported through validation and testing. This supply completes 500 start/stop cycles within just 7 seconds, demonstrating its ability to endure cycles without failing. The response time is measured for efficiency and accuracy, achieving less than 1 ms. This means power is instantaneously provided, which is critical in systems where precise timing directly affects results. 


The supply operates at over 90% efficiency, minimizing energy waste. Test results indicate that the system is designed to be reliable and functional in working atmospheres.


Consistent Laser Power Supply Operation from -30℃ to 65℃

Laser engravers are used under diverse conditions, and this supply is designed to accommodate this range. The device operates within a temperature range of -30 to 65 degrees Celsius, ensuring both safety and precision. This power supply is designed to operate without requiring additional heating or cooling equipment, thereby reducing energy consumption and operating expenses. 


Even when conditions swing from freezing to sweltering, the unit continues to perform steadily on its own. Additional climate-control systems can still be added, but they are optional rather than required. The design ensures the power supply holds its performance even when the environment is far from perfect, giving workshops confidence in its reliability.


Built-In Safety with Constant Current and Open Circuit Protection

Advanced protection systems ensure precision and safety. Constant current protection maintains a steady output and helps prevent any possible fluctuations that could distort engravings or damage materials. During operation, the engraver can draw consistent power, generating clean and consistently accurate engravings every single time. 


With open-circuit protection, power is cut during overloads, preventing tube bursts and protecting both the equipment and operators at all times. Together, these protections make the supply safe, reliable, and ready for professional use.


Durable Aluminum Housing and 30,000-Hour Service Life

The VEVOR laser power supply contains pure copper power tubes and high-quality voltage packages arranged for durability and frequent use. An average service period of more than 30,000 hours ensures operational dependability. 


Strong module parts minimize system replacements, while consistent performance during prolonged operation reduces overall costs. The combination of durability and efficiency makes the power supply economical and business-friendly.


Stable Power for Continuous Work and Professional Results

Professional engravers and cutters depend on stability, and this VEVOR laser power supply delivers. Keeping voltage and current steady prevents uneven cuts, missed engravings, or sudden halts. 


Combined with cooling and protection systems, it supports long sessions without interruptions. This stability ensures every project is finished on schedule with professional results, whether engraving delicate patterns or cutting thicker materials. For workshops that cannot afford downtime, this reliability boosts productivity and guarantees consistent output.
