Explore EVS Powers' core collection of high-performance switching power supplies, rack-mounted telecom rectifiers, and outdoor environmental cabinets built for rigorous remote applications.
Guangzhou EVS Powers Co., Ltd., is strategically situated in the premier international trade gateway city of Guangzhou, China. EVS is a pioneer, professional manufacturer, and direct factory specializing in the engineering, R&D, and bulk supply of high-reliability switching power systems, advanced DC power architectures, customizable power supply units (PSU), DC-DC converters, and industrial pure sine wave inverter systems.
We believe that client satisfaction is our absolute priority. We operate under three core pillars: uncompromising product quality as the foundation of development, rigorous process optimization as our structural cost advantage, and open technical partnerships for shared success. This commitment has enabled EVS to build long-term OEM/ODM collaborations with enterprise clients across Europe, North and South America, Australia, the Middle East, and Southeast Asia.
The global transition toward off-grid utility networks, decentralized telecom towers, and regional microgrids is redefining modern industrial electrical engineering. Today's architectures demand intelligent power systems designed to handle highly dynamic loads under extreme environmental conditions.
Next-generation 5G telecom architectures run on power-dense base stations that require dynamic power allocation. EVS meets this transition with modular rack-mounted systems that scale from 1kW to over 200kW, operating flawlessly in remote, unconditioned outdoor cabinets.
Off-grid systems are increasingly pairing photovoltaic and wind inputs with traditional DC backup rectifiers. This hybrid architecture requires rectifiers to offer smart communication protocols (like SNMP v2/v3) and wide input ranges to smoothly handle voltage swings from fluctuating renewable generation.
By moving from traditional silicon elements to Silicon Carbide (SiC) and Gallium Nitride (GaN) components, modern power systems can handle higher switching frequencies. This change reduces heat output and shrinks the overall footprint of telecom rectifier modules.
For procurement directors, systems integrators, and network operators, purchasing off-grid power components is a long-term investment. Minimizing total cost of ownership (TCO) while maximizing reliability is the baseline expectation.
Even a 1% improvement in conversion efficiency translates to thousands of dollars saved annually in large-scale telecom deployments. EVS's 95% efficiency modules (such as the EVS48100-H1B1) minimize heat loss, reducing the demand on cooling systems in outdoor cabinets.
To prevent downtime in remote off-grid locations, power architectures must feature modular designs. Using hot-swappable N+1 rectifier modules allows on-site operators to easily swap modules without taking the entire base station offline.
Procuring power supplies for desert, sub-zero, or high-humidity regions requires rugged designs. EVS's IP65 cabinets protect sensitive switching electronics from dust, moisture, and corrosive coastal air.
EVS Powers designs customized solutions for major industrial sectors, ensuring stable DC distribution and power conversions wherever utility grids are unavailable or unreliable.
We provide full-stack power solutions for cellular towers and fiber exchange nodes. Our systems feature integrated IP65 outdoor telecom cabinets, AC-to-DC air-conditioned rectifier systems, and built-in SNMP communication cards for real-time remote monitoring.
Substations require highly dependable DC control power. EVS supplies robust 110V and 220V charging cabinets (such as our 380V to 110V DC 100A rectifiers) to run circuit breakers, protection relays, and emergency signaling systems.
To shield critical manufacturing setups from power fluctuations, EVS designs high-capacity DC-DC converters (such as 48V to 380V DC 5kW systems) and industrial pure sine wave inverters that supply clean, noise-free power to automated processes.
Quality starts on the shop floor. Guangzhou EVS Powers Co., Ltd. operates a highly standardized production line equipped with automated manufacturing machines, ensuring consistent build quality and long product life.
To back up our E-E-A-T credentials, EVS subjects every power system design to a series of tests before shipment. Our on-site testing lab verifies electrical isolation, safety compliance, and long-term thermal performance.
As dynamic off-grid systems evolve, EVS is updating its tech roadmap to keep pace with changing industrial requirements.
By moving control from analog circuits to digital signal processors (DSPs), our upcoming systems will support software-configured output profiles. This design allows operators to fine-tune voltage levels and charging parameters remotely.
Integrating artificial intelligence into SNMP cards will soon allow systems to track component wear. Using real-time monitoring, systems can alert operators to degradation in filter capacitors or cooling fans before a failure happens.
We are shrinking our 3kW rectifier modules down to a smaller, sub-1U form factor. This footprint reduction allows systems integrators to pack more power capacity into crowded cabinets.
Operating critical systems in remote regions requires strict compliance with international electrical and safety standards. EVS power systems are engineered to meet global requirements, including CE, CB, FCC, and RoHS certifications. We also design products to comply with regional electromagnetic interference (EMI) and harmonic current regulations.
To support our global customers, EVS offers dedicated technical consulting, custom cabinet designs, and comprehensive after-sales services. From adjusting input voltage setups to choosing the right cabinet cooling capacity, our engineering team works with you to ensure your project's success.
