Engineered to meet rigorous global standards, our primary product lineup offers unmatched efficiency, thermal resiliency, and load compliance.
Meeting the High-Density Energy Demands of AI Clusters, Hyperscale Cloud Infrastructure, and Next-Gen Telecom Base Stations.
Modern data centers are undergoing a seismic shift. The explosive growth of artificial intelligence (AI), machine learning models, and high-performance computing (HPC) has increased average rack power requirements from 5kW–10kW to 30kW–100kW per rack. This drastic escalation demands advanced, compact power supply systems with high thermal thresholds and minimal energy wastage.
Historically, standard AC distribution was direct to the rack, but high conduction losses at low voltages forced a structural transition. Today, engineers optimize Power Usage Effectiveness (PUE) through standardized 48V DC architectures, utilizing high-efficiency rectifier systems and specialized AC-to-DC modules. By converting voltage closer to the silicon, telecom systems and cloud hyperscalers achieve up to 95%+ efficiency profiles, drastically reducing thermal loads and operational expenditure.
Our solutions directly target these pain points. By incorporating advanced components capable of wider operating ranges (including 110VDC/220VDC/380VAC input and output configurations), EVS systems deliver active power factor correction, minimal total harmonic distortion (THD), and robust EMI suppression required for global telecom networks and industrial environments.
Our industrial-grade power supplies are deployed in highly diverse environments worldwide, designed to withstand regional grid anomalies and climatic conditions.
Operating outdoors requires resilience against extreme temperatures, dust ingress, and moisture. Our IP67 outdoor project boxes and 48V telecom rectifiers power rugged base stations across Europe, the Middle East, and Southeast Asia, offering continuous operational capabilities from -40°C to +65°C.
Integrating 1U and 2U hot-swappable AC-DC converters into standard 19-inch cabinet configurations. These units provide localized DC power distributions, optimizing airflow patterns, reducing PUE, and offering clean, isolated outputs to prevent core server processing unit degradation.
Supporting modern automation assemblies with 24VDC/48VDC/110VDC high-efficiency DIN-rail systems. Tested rigorously to withstand high vibration, line transients, and sudden load imbalances, securing consistent power outputs for PLCs and robotic interfaces.

The primary driver is power density. At 12V, delivery currents are four times higher than at 48V for equivalent power loads. According to Joule's Law (P=I²R), transmission losses are proportional to the square of the current. Shifting to 48V DC distribution reduces conduction line losses by a factor of 16, allowing for thinner busbars, smaller cable configurations, and improved rack efficiency to match high-power AI server processors.
Our quality verification structure integrates optical microscopes to trace solder joint integrity, constant temperature and humidity chambers to isolate thermal drift, and specialized AC withstand voltage testers to confirm isolation barriers. Every production batch undergoes a 100% full-load burn-in run before shipping, minimizing infant mortality rates for deployed units.
