Compact 1U and embedded rack-mount structures engineered to deliver stable power to telecom cabinets, supporting critical edge computing and remote BTS stations.
Algiers, the political, cultural, and technological capital of Algeria, is undergoing a massive transformation in telecom infrastructure. With major network service providers like Algérie Télécom, Mobilis, Djezzy, and Ooredoo scaling up their networks to address 5G standards and the Internet of Things (IoT), demand for highly reliable, smart, and efficient 48V DC power supplies has surged.
However, the Mediterranean coastal climate combined with seasonal dust storms and scorching Saharan winds creates severe environmental challenges. Unlike moderate regions, Telecom Base Transceiver Stations (BTS) and outdoor enclosures in Algiers must handle high temperature spikes, significant humidity swings, and localized voltage instability. Standard power supplies suffer rapid aging or immediate thermal shutdowns under these conditions.
Guangzhou EVS Powers Co., Ltd. addresses these pain points by offering modular -48VDC power solutions designed with ultra-rugged electronics, high-temperature tolerance up to 75°C, and state-of-the-art power factor correction (PFC) mechanisms. This ensures continuous, uninterruptible operations for core network hubs in Sidi Abdellah Cyberpark, the central business district of Bab Ezzouar, and remote telecom repeaters across the Wilaya of Algiers.
High reliability, integrated SNMP modules, and flexible cabinet designs customized for industrial switches and critical IT infrastructures in Algeria.
A deep technical analysis of modular 48V DC power system integration, load balancing, and battery management strategies for North African enterprise clients.
When operating in high thermal environments such as central Algiers, power systems lose efficiency due to heat dissipation challenges. This translates into increased operational cost (OPEX) due to forced cooling. Guangzhou EVS Powers Co., Ltd. addresses this via advanced topologies that maintain a consistent 95.5% efficiency rating.
By utilising digital signal processors (DSPs) to control the conversion stages, EVS power modules optimize switching losses dynamically. In addition, our N+1 hot-swappable configuration guarantees that even if a single rectifier module fails under extreme conditions, the system loads are seamlessly redistributed without causing network down-time.
A critical issue for telecom operators in Algeria is the deep discharge of battery backup banks. EVS 48V telecom systems come integrated with smart dual-LVD protection (LLVD and BLVD). This ensures that when utility power drops:
In many areas surrounding Algiers, the public utility grid can experience drops down to 100V AC or spikes exceeding 270V AC. Standard telecom rectifiers often shut down or burn out. EVS embedded power supplies utilize wide-input tolerance engineering, ensuring stable -48VDC output even during severe grid fluctuations. This makes our systems highly compatible with rural electrification microgrids and hybrid diesel-solar setups.
"Implementing high-efficiency EVS 48V power converters saves up to 15% of annual power consumption per BTS station in North Africa when compared to legacy transformer-based solutions, directly driving down the host enterprise's TCO and carbon footprint."
Our advanced production workflows, high-precision assembly lines, and testing equipment ensure every 48V power module meets global CE, RoHS, and strict telecom carrier standards.

As the global telecom sector targets carbon-neutrality and edge intelligence, energy systems must evolve from passive rectifiers to smart nodes.
Integrating solar MPPT controllers directly with the 48V DC bus allows telecom tower sites in Algeria's solar-rich southern provinces to transition seamlessly between photovoltaic power, grid power, and battery storage, drastically reducing diesel generator fuel reliance.
By utilizing advanced SNMP v3 and Modbus interfaces, future systems will feedback load trends, ambient thermal profiles, and battery impedance states to centralized cloud management systems, enabling predictive maintenance cycles before a hardware fault occurs.
Realizing higher output capacities (up to 6kW) in standard 19-inch 1U modules through modern Gallium Nitride (GaN) switching components. This frees up rack space inside telecom enclosures for standard baseband units (BBUs) and network processing servers.
Designed for central offices, massive industrial stations, and data center backups serving the Greater Algiers municipal and industrial areas.
Answers to common engineering questions concerning installation, environmental protection, and procurement protocols in North Africa.
The -48VDC (negative 48 volts) configuration is the industry standard for telecommunication infrastructure globally. Using negative voltage significantly mitigates the rate of electrochemical corrosion on copper connections and wires in moist or humid climates, such as coastal areas in Algiers. Furthermore, 48V is low enough to prevent severe shock hazards to technicians while being high enough to minimize current losses over typical rack-run cable lengths.
Our rectifiers feature a wide input voltage window (from 80VAC up to 300VAC). The integrated Active Power Factor Correction (APFC) allows modules to adjust switching cycles dynamically. This ensures that the output stays stable at 48V DC, shielding base station loads from brownouts or sudden overvoltage transients without draining the local backup battery.
EVS 48V power systems support advanced network controllers equipped with RJ45 Ethernet ports. The integrated system supports SNMP (v1/v2c/v3) and Modbus protocols. This allows network engineers in central operations centers in Algiers to monitor rectifier temperature, output voltage, charge current, and relay alarms in real-time, greatly decreasing maintenance overheads.
Our embedded power controllers can be programmatically configured to support Lithium Iron Phosphate (LiFePO4) battery packs as well as Valve Regulated Lead-Acid (VRLA) batteries. The charging profile, float voltage, and low-voltage disconnect (LVD) parameters can be customized directly via the browser interface or the system console.
Yes. All EVS 1U and embedded rectifiers are 100% hot-swappable. The system controller automatically registers the removal or insertion of modules and performs load balancing without interrupting the output power to the load, providing zero downtime operations.
Guangzhou EVS Powers Co., Ltd. products comply with CE, RoHS, and international electrical safety standards.
