Discover our primary selection of industrial power supplies, weatherproof cabinets, and hot-swappable distribution solutions.
In the modern era of rapid digital transition, high-reliability electrical enclosures have moved from simple sheet-metal junction boxes to smart, thermally engineered infrastructure critical to national grids, telecom operators, and industrial automation. As critical components of localized network infrastructures, electrical enclosures shield valuable modules from severe weather conditions, high UV indexes, moisture, salt air erosion, and physical security threats.
Globally, the explosive expansion of 5G cellular communication networks, localized renewable energy storage systems (BESS), and Smart City IoT grids demands high-performance weatherproof enclosures. The configuration of electrical enclosures requires exact compatibility with internal system payloads. Systems like AC-DC rectifier modules, battery banks, power distribution units (PDUs), and network switches require dedicated physical protection and sophisticated thermal management systems to ensure continuous operation, preventing critical component degradation over time.
Based in the international trade hub of Guangzhou, Guangzhou EVS Powers Co., Ltd. is a leading manufacturer specializing in industrial switching power supplies, integrated DC power systems, custom power supply units, DC-DC step-down/step-up converters, pure sine wave power inverters, and fully-equipped electrical enclosure systems. We work as dedicated partners for global system integrators and electrical distributors, prioritizing cost-efficiency and product safety.
EVS Powers provides high-precision OEM and ODM capabilities. We help clients turn mechanical and electrical designs into commercial realities. We ensure product performance matches strict regulatory rules across major international markets, including Europe, North and South America, Australia, the Middle East, and Southeast Asia.

As telecom equipment is increasingly deployed in remote areas, specialized cabinets must adapt to regional environments. Coastal deployments require C5-M high corrosion resistance, while desert installations need passive solar shields and sand-filtration louvers. Choosing correct cabinet specs helps operators avoid premature electrical faults and extend maintenance cycles.
Modern electrical enclosures must support integrated remote monitoring units (RTUs), smart locks, and SNMP-enabled distribution switches. Dynamic power monitoring allows network operation centers (NOCs) to track internal thermals, humidity levels, and electrical load balances, facilitating proactive, data-driven maintenance instead of reactive emergency responses.
Choosing a reliable Chinese manufacturer like EVS Powers gives companies direct access to a mature component ecosystem. The local availability of hot-dip galvanized steel, polyurethane gasketing, CNC press brakes, and automated assembly systems allows us to maintain stable production speeds and delivery timelines, even for highly customized orders.

Ingress Protection (IP) ratings classify the degree of protection against dust and liquid ingress. IP55 ensures protection against dust deposits (without harmful buildup) and low-pressure water sprays from any direction, making it ideal for standard outdoor telecom stations with dynamic thermal ventilation. IP66 offers complete dust protection and seals against high-velocity water jets, suitable for marine or extreme industrial cleaning zones.
We use double-skin metal sheets separated by specialized fire-retardant thermal insulation (like PU board or glass fiber) to minimize solar heat transfer. Active cooling systems can then be integrated, ranging from simple air filter fan systems to heat exchangers or high-capacity AC220V air conditioning units. This keeps the internal temperature within the optimal range for telecom gear and battery systems.
Yes. Our engineering division provides complete OEM and ODM design customization. We can adjust inner mounting rails (e.g., standard 19-inch rack frames), modify rack heights (such as 42U, 32U, or 22U), configure customizable cable entry ports, and design dedicated battery compartments to match your installation plan.
All power supply units, DC-DC converters, and telecom rectifiers are manufactured in accordance with strict international guidelines. This includes CE compliance, RoHS material tracking, and ISO 9001:2015 factory workflow management. Our testing protocols, including the AC Withstand Voltage Test and high-temperature environmental aging, ensure high field reliability.
For large products like our 42U outdoor enclosures, we use multi-layer packaging protection. This includes heavy-duty edge guards, bubble wrap, dustproof stretch wraps, and high-strength wooden crates to secure units on pallets during sea freight transit from the port of Guangzhou.
