Uninterruptible Power Supplies (UPS) for three-phase industrial applications are critical assets for maintaining operational continuity in environments where power quality and availability are non-negotiable. These systems, commonly referred to as three-phase online UPS or industrial UPS units, are designed to provide clean, regulated, and backup power to sensitive loads. They typically operate with input voltages of 380V, 400V, or 480V AC at 50/60 Hz, and are available in power ratings from 10 kVA up to several MVA. Key technical specifications include double conversion topology (VFI-SS-111), which isolates the load from raw utility power, ensuring zero transfer time during outages. Units often feature IGBT rectifiers, PWM inverters, and advanced battery management systems for extended runtime. The number of phases (3P input, 3P output) is standard, with options for parallel redundancy (N+1) and integrated static bypass switches for maintenance.
Three-phase UPS systems are deployed across a wide range of critical sectors, including data centers, hospitals, pharmaceutical manufacturing, oil and gas facilities, and industrial automation plants. They are installed in dedicated electrical rooms or server racks, often integrated with distribution panels, power distribution units (PDUs), and generator sets. In manufacturing environments, they protect PLCs, variable frequency drives (VFDs), and robotic controllers from voltage sags, surges, and frequency variations. For mission-critical applications like semiconductor fabrication or continuous process industries, these UPS units ensure zero downtime and protect against data loss or equipment damage.
Within our catalog, the LE49 category includes a comprehensive selection of three-phase UPS systems and their essential subcategories. Key articles include the LE49-10KVA, LE49-20KVA, LE49-40KVA, LE49-60KVA, and LE49-100KVA models, each designed for specific power requirements. The article code structure typically follows the pattern LE49-[PowerRating]KVA, where the numeric suffix indicates the apparent power in kilovolt-amperes. For example, LE49-30KVA denotes a 30 kVA unit. We also offer modular UPS systems like the LE49-MOD-50 and LE49-MOD-100, which allow for scalable capacity and redundancy. Accessories such as external battery cabinets (LE49-BAT-XX), maintenance bypass panels (LE49-MBP-XX), and remote monitoring modules (LE49-RMM-01) are available to enhance system functionality.
