3KVA Online UPS Power Supply - High Frequency True Online Double Conversion for Data Centers & Critical Systems
The HS (HTS) Series 3KVA online uninterruptible power supply represents a premium-grade solution in the realm of high-frequency, true online double-conversion UPS technology. Engineered for mission-critical environments such as data centers, server rooms, telecom infrastructure, and enterprise computing networks, this unit delivers seamless power continuity with zero transfer time, ensuring uninterrupted operation during utility outages or voltage fluctuations. Designed to support single-phase input and output configurations, it offers scalable capacity from 1kVA to 10kVA, making it ideal for small to mid-sized facilities requiring reliable, efficient, and intelligent backup power.
At its core, this online UPS leverages advanced digital control systems and high-efficiency power conversion circuits to maintain stable performance under varying load conditions. With an impressive efficiency rating of up to 90% in AC mains mode and a power factor of 0.8–1.0, it reduces energy waste while maximizing usable output. Its wide input voltage range (160–300VAC), coupled with robust surge protection and low harmonic distortion (<3% THD), ensures compatibility across diverse global electrical grids—from fluctuating utility supplies in developing regions to tightly regulated systems in industrialized nations. The system’s pure sine wave output guarantees clean, stable power delivery to sensitive electronics, minimizing risks of overheating, data corruption, or hardware failure.
Key features include intelligent battery management that extends battery life through optimized charging algorithms, a 35° adjustable LCD display panel (for models above 6kVA), and comprehensive real-time monitoring of load status, battery health, and operational modes via intuitive interface feedback. Optional SNMP card integration enables remote diagnostics and centralized IT asset management, aligning with modern cloud-based infrastructure practices. Additionally, cold start capability allows the UPS to initiate without external power—ideal for emergency scenarios where grid availability is uncertain. A built-in self-diagnostic function at startup verifies internal components, enhancing reliability and reducing downtime risk.
This UPS excels in demanding environments due to its compact footprint, lightweight design, and noise-reduced operation (<50dB). Whether deployed in a rack-mounted configuration or as a tower unit, it adapts effortlessly to space constraints in offices, labs, or telecom cabinets. The unit supports both standard lead-acid batteries and optional lithium iron phosphate (LiFePO4) battery options for extended runtime and longer service life—particularly beneficial in locations with frequent power interruptions or limited maintenance access.
Common applications span across industries: IT infrastructure providers, network operations centers, medical equipment setups, manufacturing automation systems, and retail POS terminals. Its ability to handle nonlinear loads like servers, routers, and LED lighting makes it suitable for hybrid workspaces where multiple device types share a common power source. The inclusion of RS-232 communication ports (with optional USB/SNMP expansion) facilitates integration with existing monitoring software platforms including Windows, Linux, Unix, and macOS ecosystems.
Users consistently praise its silent yet powerful operation, especially when compared to older rotary or line-interactive units. Many note how the clear LCD display simplifies troubleshooting during outages, while others appreciate the flexibility in battery configuration—allowing customization based on budget, physical space, and desired backup duration. One user highlighted how the 0ms transfer time prevented critical database transactions from being interrupted during a regional blackout—an outcome that would have otherwise led to significant business disruption.
Frequently asked questions often center around battery longevity and environmental resilience. For instance, users inquire about optimal charging cycles; the system employs smart charge profiles that balance speed and battery preservation, typically achieving 90% charge within 4–7 hours depending on model size. Regarding operating conditions, the unit functions reliably between 0°C and 40°C with humidity levels below 90% RH—making it well-suited for both climate-controlled server rooms and less controlled industrial settings. When paired with external battery banks, the runtime can be significantly extended, offering flexibility for extended blackouts or planned maintenance windows.
