Engineered to withstand dense electromagnetic environments and meet rigorous commercial requirements in North America.
As the primary financial and logistical node of the American Midwest, the Chicagoland area represents one of the world's most sophisticated industrial power markets. Driven by massive data center clusters in Elk Grove Village, Northlake, and Franklin Park, along with extensive transportation hubs surrounding O’Hare International Airport, local demand for continuous, reliable power systems is unmatched. Operating these systems requires localized technical adaptation to manage Chicago’s extreme seasonal temperature swings while complying with the strict fire and safety codes mandated by the city.
For operations in Chicago, power cabinets cannot simply be generic steel boxes. They must serve as intelligent micro-environments designed to protect critical switching modules, battery chargers, and rectifiers from ambient conditions, high harmonic distortions, and local grid transients. Guangzhou EVS Powers Co., Ltd. fills this technical gap by delivering custom industrial power systems, including GZDW DC distribution panels and IP45/IP54 telecom shelters designed for seamless integration into Chicagoland networks.
From automated precision component placement to systematic burn-in and electrical testing protocols, our manufacturing processes guarantee field reliability in the US and globally.
Guangzhou EVS Powers Co., Ltd. operates a vertically integrated manufacturing plant in Guangzhou, a leading global trade hub. EVS specializes in the design, engineering, and manufacturing of high-performance switching power supplies, DC-DC converters, industrial DC power systems, and telecom grade server racks. Quality is the core foundation of our development process. With strict adherence to international standards and robust ODM/OEM capabilities, we provide power solutions designed for complex environments in North America, Europe, Australia, and the Middle East.
Our production facilities utilize modern machinery and strict testing processes to ensure every product delivers peak performance under demanding field conditions. Below is a detailed view of our multi-phase manufacturing workflow:













Built for resilience, compliance, and optimized energy efficiency.
Understanding local requirements ensures smooth commercial installation and safe long-term operation.
Unlike standard designs, power cabinets deployed in the City of Chicago must meet rigorous safety requirements. EVS configurations utilize high-grade metal conduit access plates, fire-retardant internal wiring, and dedicated terminal ground connections to simplify inspection and permitting processes.
Our internal rectifiers, modules, and distribution switchgear assemblies are designed to align with UL 60950-1, UL 62368-1 for telecom networks, and UL 508A for industrial control panels, ensuring stable electrical integrity and performance.
With seasonal variations ranging from extreme winter cold to hot, humid summers, our systems feature robust cooling configurations. Internal climate options range from ambient convection units to active forced-air and thermostatic heat exchangers, protecting sensitive power components from thermal stress.
To operate reliably in heavy industrial, utility, and telecom environments, power cabinets must undergo rigorous electrical, physical, and environmental testing. Our test center ensures that rectifiers, converters, and electrical components meet strict performance and durability standards.
EVS utilizes constant temperature and humidity chambers, digital AC withstand voltage testers, and optical microscopes to identify and resolve potential issues during the manufacturing phase. These comprehensive testing and design workflows ensure our cabinets deliver stable and reliable operation in the field.






The modernization of utility grids and expansion of edge-computing networks require smart, integrated power systems.
Modern GZDW systems incorporate RS485 and SNMP monitoring protocols, enabling remote telemetry oversight for Chicago utility managers.
Utilizing high-frequency silicon carbide (SiC) and GaN semiconductors enables higher energy efficiency and reduces thermal loss in compact footprints.
Integrating high-density AC-DC modules with distribution and backup battery systems in space-efficient 19" subracks maximizes usable floor space.
Utilizing dual-skin insulated panel configurations alongside custom-designed active cooling systems protects sensitive electronics in unconditioned environments.
High-efficiency conversion modules and protective metal enclosures designed for industrial and telecom networks.
Answering key technical and logistical questions for procurement professionals in Chicago and North America.
EVS power cabinets are constructed using cold-rolled steel enclosures with dedicated ground buses and secure metal conduit knockouts. This structural design prevents fire propagation and meets the strict requirements of the Chicago Electrical Code regarding electrical wiring containment.
Standard configurations typically ship within 4 to 6 weeks. For custom OEM/ODM projects requiring tailored structural fabrication or unique internal voltage distributions, engineering approvals take approximately 2 weeks, followed by a 6 to 8-week manufacturing window.
We partner with global logistics networks to offer DDP, CIF, and FOB shipping terms. For Chicago customers, we coordinate transportation to local distribution centers, managing import clearance procedures to ensure compliance with US Customs and Border Protection standards.
We offer multiple cooling configurations based on heat load requirements, ranging from standard ventilation louvers for controlled indoor rooms to active cooling setups featuring internal thermostat-controlled AC fans, heat exchangers, or dedicated HVAC systems for high-heat environments.
Yes. Our indoor telecom racks are designed in accordance with EIA-310 standard 19-inch mounting dimensions. This layout provides compatibility with standard network equipment, servers, batteries, and power modules from major global manufacturers.
