High-efficiency systems designed to protect and support telecommunications, data centers, and advanced manufacturing microgrids in Rajshahi and worldwide.
As the primary urban center of north-western Bangladesh, the Rajshahi metropolitan division is experiencing a monumental transition from an agrarian base to an industrialized economy. Driven by government initiatives like the Bangabandhu Hi-Tech Park, Rajshahi, and rapid digitalization across administrative and banking sectors, the region has seen an exponential surge in demand for uninterrupted, high-integrity electrical power.
Unlike standard office settings, industrial complexes, manufacturing mills (including Rajshahi's historical silk and agro-processing clusters), and telecom nodes operate under challenging grid conditions. Voltage fluctuations, sag incidents, frequency deviations, and complete blackouts pose immediate risks to expensive automated machinery, server farms, and manufacturing lines. The implementation of high-performance, modular UPS power supplies and active rectifiers is no longer an afterthought; it is a critical operational safeguard.
While local assembly hubs in Rajshahi can satisfy standard low-voltage demands, complex municipal projects and high-volume industrial installations require advanced supply chains, stringent component verification, and rigorous testing protocols that only mature international manufacturing centers can guarantee. This is where Guangzhou EVS Powers Co., Ltd. serves as a crucial partner.
Our facility in Guangzhou bridges the gap for regional distributors, contractors, and industrial players in Rajshahi. By incorporating advanced electronic topologies—such as resonant soft-switching technology and DSP-driven digital control loops—EVS Powers provides systems with up to 95% efficiency, reducing localized heating and lowering the Total Cost of Ownership (TCO) for enterprises. Our extensive OEM/ODM manufacturing capability ensures that components are engineered to withstand the ambient heat, humidity, and atmospheric salinity typical of the Gangetic delta region.
Every rectifier, inverter, and DC UPS module undergoes a multi-stage production and quality assurance workflow to ensure field survivability under harsh operating conditions.
A power supply is only as dependable as the equipment that validates its limits. At Guangzhou EVS Powers Co., Ltd., we have established a state-of-the-art testing lab featuring specialized test equipment to verify electrical and mechanical performance. This guarantees that systems installed in remote telecom cabinets or heavy industrial zones function flawlessly.
Our commitment to reliability is demonstrated through rigorous laboratory testing. We perform advanced diagnostics to ensure each unit meets dynamic load requirements, thermal dissipation standards, and strict EMI/EMC parameters. Our quality control cycle includes:
The roll-out of high-speed LTE and 5G networks in Rajshahi Division requires thousands of base transceiver stations (BTS) deployed in both urban centers and rural locations. These BTS systems depend heavily on 48V DC power supplies and outdoor telecom network cabinet enclosures. EVS Powers provides tailored steel sheet metal fabrication enclosures equipped with integrated rack-mount rectifier systems. Designed with dynamic cooling vents, dust protection filters, and moisture-resistant gaskets, these systems keep telecom nodes operational even under critical monsoon conditions.
Substations, chemical processing lines, and heavy manufacturing utilities in the Rajshahi industrial zones require dependable DC reserve banks. If control circuitry power is lost, entire plants can shut down. Using EVS 110V and 30V high-capacity industrial battery chargers, engineering teams can configure redundant, parallel systems. This setup protects electrical switchgears and maintains backup power for plant automation controllers during emergency grid interruptions.
As Bangladesh increases its commitment to renewable energy, hybrid microgrids incorporating solar photovoltaic arrays and diesel backup generators are coming online across the Rajshahi region. EVS pure sine wave inverters are engineered to seamlessly convert DC battery reserves to clean, single-phase AC electricity. This provides critical load matching and grid-stabilization characteristics required by regional medical colleges, educational institutions, and banking server centers.

Operating high-frequency converters in regions like Rajshahi, Bangladesh requires solving two main challenges: ambient heat (which often exceeds 40°C in the summer) and power grid surges. Standard, commercial-grade electronics degraded quickly under these conditions. The engineering team at Guangzhou EVS Powers address these issues through structural design improvements:
Traditional hard-switching power converters experience energy loss during every transition state. By using ZVS topology, our industrial rectifiers, such as the 110V 20A High-Frequency DSP Digital Control module, reduce switching loss. This configuration enables a compact form factor while keeping operational efficiency above 92%, resulting in lower heat generation inside sealed telecommunication cabinet units.
High relative humidity and dust accumulation can bridge high-voltage components on a PCB, leading to short circuits. To prevent this, EVS Powers applies a rigorous glue-filling (potting) and conformal coating process across our converter lines. This protective layer seals out dust, humidity, and atmospheric pollutants, ensuring long-term reliability in non-climate-controlled environments.
Our digital control loops use high-speed DSP microcontrollers. Rather than relying on slower analog response networks, the digital system monitors output voltages and currents in real time. This ensures stable power output even during extreme input voltage fluctuations (varying from 170VAC to 264VAC), protecting sensitive equipment down-line.
For engineering, procurement, and construction (EPC) contractors in Bangladesh, finding reliable manufacturers is critical for long-term project success. Key steps for a smooth integration of EVS power systems include:

We manage shipping logisics from our Guangzhou center. For projects in Rajshahi, products are typically shipped by sea from Guangzhou/Shenzhen port to Chittagong Port, which takes about 14 to 21 days. For urgent equipment needs, air freight to Hazrat Shahjalal International Airport in Dhaka takes 3 to 5 days, followed by domestic transport to Rajshahi.
Yes. As an OEM and ODM supplier, we can adjust output voltages (e.g., 48V to 24V, 110V to 48V, or customized single-phase configurations) to match your target parameters. Our engineering team can modify design schematics, component selections, and enclosure dimensions to fit your specifications.
Our industrial-grade units are engineered with high-temperature components and built-in thermal protection. When temperatures rise, the systems utilize smart fan cooling and thermal derating protection to maintain stable operation. They are designed to operate safely in environments up to 55°C without system shutdown.
Our digital charging systems support multiple battery profiles, including Lithium-Ion (Li-ion), Lead-Acid, and Nickel-Chromium (Ni-Cr). The charging profiles are pre-programmed or adjustable via the digital control interface to ensure optimal charging voltage and cycle life.
Yes, several models—including our EVSPOWER SNMP EVS-A3-1048 series—feature built-in network communication ports. This allows operators to monitor system performance, track load conditions, and receive real-time fault alerts through a central SNMP interface.
