ETOMMENS DC power supply manufacturer, ETOMMENS is a professional DC power supply manufacturer located in Songshan Lake Hi-Tech Park, Dongguan, China. Since our establishment in 2015, we have concentrated on independent R&D, precision production and global supply of regulated DC power sources. We mainly serve overseas distributors, university laboratories, electronics maintenance workshops, new energy testing factories and industrial research clients across Europe, North America and other global markets.
Our factory spans over 4000 square meters, equipped with full sets of advanced production and testing equipment, including automatic SMT chip mounters, wave soldering stations, high-precision calibration instruments and continuous aging test racks. We have more than 10 standardized production lines, with a stable monthly capacity of over 10,000 power supply units.
Almost all core assembly, testing and calibration processes are completed in-house. This in-house workflow allows us to strictly control product quality, stabilize production lead time and maintain competitive pricing for bulk wholesale orders. Our R&D team consists of more than 20 experienced electronic engineers. We keep cooperating with local research institutions to continuously optimize circuit architecture, control firmware, protection logic and heat dissipation design.
Our product portfolio covers DC power supplies within 6000W, including bench adjustable power supplies, dual or multi-channel power sources, high precision low-ripple models, rack-mount industrial power supplies and programmable DC power supplies.
All our units support automatic CV and CC mode switching. Standard built-in protections include OVP, OCP, OTP and short-circuit protection to safeguard both the power supply and the devices under test. Optional communication interfaces such as RS232, RS485 and USB can be configured for remote control and upper-computer connection.
These features make our products suitable for automated aging test lines, lithium battery cycle testing, LED module testing, student lab experiments and electronic product debugging. Our adjustable DC power supply series is widely used for electronics repair and lab testing.
As a factory focusing on long-term B2B partnerships, we provide flexible OEM and ODM services for global dealers. You can customize output voltage and current parameters, front panel layout, brand logo printing, packaging styles and communication protocols to fit your local market demands.
Whether you need ready standard models or fully customized power solutions, our technical team can offer one-stop support, from sample validation and performance calibration to mass production and shipment. All finished products undergo strict performance inspection and safety testing before delivery, and hold export certifications that meet the mainstream requirements of the EU and North America.
Rigorous quality control runs through every production stage. We carefully select reliable core electronic components to lower output ripple and noise. Every finished power supply will go through 2 to 4 hours of continuous aging testing.
This strict screening ensures stable performance during long-hour nonstop operation and effectively reduces failure complaints from your end buyers. Unlike trading companies, we are the direct manufacturer, which means we can deliver faster technical guidance, accessory supply and after-sales support directly.
If you need automated test solutions, check our programmable DC power supply. We sincerely welcome distributors, resellers and system integrators to contact us for cooperation.
We provide transparent wholesale price lists, relatively flexible MOQ and stable inventory arrangements to support your business growth. Feel free to reach our sales team to get product catalogs, sample quotation and complete technical datasheets.
