Premium 19-inch rack-mounted designs delivering high efficiency, smart monitoring, and uninterrupted transition to match the requirements of major Malaysian carriers.
Malaysia is undergoing a rapid digital transformation led by the government's Jalinan Digital Negara (JENDELA) initiative and the accelerated rollout of the 5G Single Wholesale Network (SWN) by Digital Nasional Berhad (DNB). High-speed fiberization, industrial IoT deployments, and rural connectivity initiatives are expanding network topologies from metropolitan areas like Kuala Lumpur and Penang to remote zones in Sabah and Sarawak.
This rapid deployment presents unique challenges for local system integrators and telecom contractors. The tropical climate in Malaysia—characterized by persistent high temperatures (averaging 32°C), high humidity levels exceeding 80%, and intense seasonal lightning storms—imposes stringent performance criteria on power backup systems. Any power instability or grid spike from local utility lines (like TNB) can cause costly downtime at Base Transceiver Stations (BTS), micro-cell sites, and telecom hubs.
Our industrial-grade telecom inverters are specifically customized to address these climate and infrastructure challenges. Designed with active temperature compensation, tropicalized PCB conformal coatings, and low electromagnetic interference (EMI), they ensure optimal 24/7 conversion stability for sensitive networking gear.
Aligning with international telecom standards to bring high-efficiency power conversion, hot-swappable architectures, and modern control loops to the Southeast Asian market.
Utilizing advanced double-conversion topologies and soft-switching technologies, our inverters operate at up to 95% peak efficiency. This directly reduces thermal losses, slashes cooling costs, and supports corporate sustainability targets for green telecom networks.
Engineered in ultra-compact 1U, 2U, or 3U heights, our rackmount structures integrate seamlessly into telecom cabinets alongside active networking devices, rectifiers, and lithium battery banks.
Equipped with high-performance Digital Signal Processors (DSP), our systems support intelligent battery management, real-time waveform monitoring, and auto-bypass configuration to optimize performance dynamically.
Guangzhou EVS Powers Co., Ltd. is located in the international trade city of Guangzhou, China. EVS is a professional, high-tech manufacturer specializing in switching power supplies, DC power systems, custom power supply units, DC-DC converters, and industrial telecom inverter series. We also offer OEM and ODM electronic solutions engineered to custom specifications.
Our core philosophy positions customer satisfaction as our priority, product quality as our foundation, and cost-effective structural design as our competitive advantage. Backed by exceptional credit standings and premium technical service, we have built a solid reputation and established long-term collaborations with clients across Europe, South and North America, Australia, the Middle East, and Southeast Asia—with a dedicated focus on the expanding Malaysian market.
By leveraging sharing-based knowledge, engineering technology, and manufacturing experiences, we support local partners in Malaysia to co-develop reliable telecom power systems that withstand demanding regional grid profiles. Our state-of-the-art facility is equipped with automated assembly lines, high-precision test instrumentation, and environmental test chambers to ensure every unit shipped adheres to global quality regulations.
To qualify for deployment in high-reliability applications, each production batch undergoes strict quality validation. Outdoor enclosures in sites located across East and Peninsular Malaysia face persistent humidity and thermal challenges. Our test laboratory reproduces these environmental environments using high-precision stress chambers, ensuring long-term stable performance in the field.
From component verification at incoming inspection to functional stress testing on the finished product, we maintain high engineering standards at every phase of production.
A comprehensive line of robust, rackmount power systems designed to convert DC battery bank power (12V, 24V, 48V, 110V, 220V) into stable AC utility power.
Providing high-precision engineering and variable configurations for targeted industrial communication systems and utilities.
From dense urban micro-cells in Kuala Lumpur to remote utility sites in Sarawak, our inverters provide stable, clean power.
Modern 5G massive MIMO antennas and baseband units demand clean power supply paths. Our rackmount 48VDC to 220VAC inverters convert reserve DC battery energy to reliable AC power, keeping local communication lines active during grid transients.
Consult Base Station Layout →Utility providers and public transport operators rely on stable DC systems. Our 110VDC and 220VDC to AC pure sine wave models offer optimal galvanic isolation, protecting monitoring equipment from high-frequency grid noises.
Consult Utility Standards →Remote base stations often rely on solar PV hybrid power. The high energy conversion efficiency (up to 95%) of EVS power systems minimizes overall losses, reducing the required sizes of local battery banks and solar arrays.
Consult Hybrid Remote Setup →Our telecom inverters utilize a high-performance DSP (Digital Signal Processor) configuration to achieve fast and accurate control loop feedback. By monitoring voltage waveforms in real-time, the inverter maintains output THD (Total Harmonic Distortion) below 3%, protecting sensitive microwave links and telecommunication switches from grid distortions.
Additionally, they support integrated communications (RS485, RS232, and SNMP) to allow real-time monitoring of input voltages, output loads, working temperatures, and alarm states from centralized Network Operations Centers (NOCs).
For high-availability requirements, the built-in static bypass switch guarantees a transfer time of less than 4 milliseconds. If an overload or a transient internal fault occurs, the system automatically transfers the critical load to utility bypass power without causing equipment resets.

Our telecom rackmount inverters feature a built-in zero-crossing static transfer switch with a typical transfer time of less than 4ms. This ensures that telecommunication routers, network switches, and optical transmission terminals operate continuously without resetting during utility power interruptions.
Every industrial inverter unit destined for tropical regions undergoes a specialized manufacturing process. This includes applying a thick layer of industrial-grade conformal coating to the internal PCBs to prevent corrosion from high humidity and salt mist. Additionally, our intelligent variable-speed fan cooling design prevents hotspots inside outdoor telecom enclosures.
Our systems support standard RS485 and RS232 connections as well as SNMP options. These interfaces enable operators to monitor parameters like input voltage, load levels, real-time operating temperatures, and active alarms from central monitoring software.
