Highly efficient 1U to 5U embedded rack systems designed for rapid deployment in metropolitan centers and remote off-grid regions.
Pakistan’s telecommunications sector is experiencing exponential growth, driven by massive mobile data usage and upcoming 5G preparatory rollouts. However, network operators face severe operational challenges, primarily centered on power reliability and grid instability. Unscheduled load shedding, severe voltage fluctuations (ranging from 120VAC to over 280VAC), and high ambient temperatures reaching 50°C in Sindh and Punjab provinces demand robust power backup architectures.
Traditional reliance on diesel generators (DG) incurs prohibitive OPEX due to soaring fuel costs and maintenance overheads. To counter this, tier-1 operators like Jazz, Zong, Telenor, and PTCL are transiting to high-efficiency, hybrid solar-rectifier topologies utilizing -48V DC power systems paired with advanced lithium battery storage.
Telecom power rectifiers deployed in Pakistan must feature a wide input voltage window (typically 80V to 300VAC) and built-in surge protection (SPD) to survive transient grid surges caused by atmospheric lightning and localized utility switching.
From high-density urban macro base stations to remote off-grid locations in Khyber Pakhtunkhwa and Balochistan, our systems are optimized for local operating conditions.
In rural parts of Punjab, Sindh, and Khyber Pakhtunkhwa, grid power is either non-existent or highly unstable. Our systems interface seamlessly with MPPT solar charge controllers, utilizing the 48V DC bus to prioritize solar harvest during daylight and cycle lithium storage at night, dropping diesel usage by up to 85%.
Metropolitan sites in Karachi, Islamabad, and Lahore face tight spatial constraints. EVS 1U rack-mount rectifiers (EVS4860-H1A2) provide high-density power delivery of up to 3600W, making them ideal for space-constrained pole-mounted enclosures and outdoor micro-cabinet integrations.
For large-scale switching centers and data hubs requiring up to 12KW, the EVS48200-H5B4 system configuration offers N+1 modular redundancy. Combined with SNMP communications, facility managers maintain absolute control over the continuous DC load and battery backup parameters.
Guangzhou EVS Powers Co., Ltd., is located in the global international trade city of Guangzhou, China. As a premier professional manufacturer of switching power supplies, DC power systems, rectifier units, DC-DC converters, and power inverters, we regard our client’s satisfaction as our primary mission.
Our export strategy for the Pakistani market is built upon supply chain resilience. Through "China Factory 4.0" manufacturing practices, we integrate automated assembly line configurations with strict component-level tracking. This mitigates supply delays, guarantees part consistency, and ensures we maintain high product reliability alongside cost-saving competitive advantages.
We actively collaborate with international partners across Europe, North and South America, Australia, the Middle East, and Southeast Asia, sharing knowledge, technology, and engineering experience for mutual benefit and development.
Every single power supply system we ship to Pakistan undergoes exhaustive design validation, environmental simulation, and safety verification. Our specialized laboratory testing guarantees that the rectifier modules handle extreme voltage fluctuations and peak temperature operation profiles common to Pakistani grid environments.

When engineering power systems for Pakistan's telecom networks, selecting the correct rectifier size, control interface, and battery capacity is essential to prevent downtime. Consider the following key technical parameters:
Determine the maximum continuous load of your active gear (BTS card shelves, transmission nodes, and remote radio heads - RRH) and add standard battery charging requirements. A site with a 50A continuous load should implement a rectifier capacity of at least 100A (e.g., the EVS48200-H5B3 configured with three 50A modules) to ensure simultaneous load provisioning and rapid battery recharge after grid outages.
Uncontrolled battery depletion degrades lifetime and risks system lockup. Our integrated controllers feature programmable Low Voltage Load Disconnect (LVLD) and Low Voltage Battery Disconnect (LVBD). This disconnects non-critical transmission lines first, preserving vital communications before a complete battery shutdown occurs.
Yes. Our telecom power systems feature an ultra-wide AC input range of 80VAC to 300VAC. The rectifier modules dynamically regulate output power, de-rating safely under low input voltage phases to maintain a clean -48V DC bus without disconnecting the load or draining batteries.
Absolutely. The integrated SNMP/Modbus control interface supports adjustable charging curves, voltage thresholds, and temperature compensation offsets, making them compatible with modern Lithium battery BMS systems as well as standard VRLA batteries.
Our systems include integrated Web Browser interfaces, SNMP (v2c/v3), and Modbus protocols. This allows network operation centers (NOC) to monitor rectifier efficiency, temperature, active alarms, battery charge status, and load current configurations remotely.
All EVS telecom power products are designed, manufactured, and tested to meet international standards. They carry CE and RoHS certifications, ensuring compliance with global electrical safety and ecological norms.
