Backup Commercial Uninterruptible Power Supply UPS System 20kVA To 60kVA
Integrating a built-in isolation transformer as its core advantage, the Online Modular UPS with Isolation Transformer is engineered for mission-critical scenarios—from medical facilities and data centers to industrial automation systems. It stands out for delivering clean, stable power while shielding sensitive equipment from electrical disturbances, making it a reliable choice for applications where power quality directly impacts operational safety.
With a modular design supporting 20kVA to 60kVA initial capacity (and requiring independent transformer cabinets for systems over 60kVA), it offers flexible customization to match specific power demands. Adopting a three-in-three-out architecture and advanced DSP control, it achieves 92% efficiency in normal mode, 95% in ECO mode, and maintains 92% efficiency even in battery backup mode. Fully compliant with industry safety standards, its user-friendly monitoring interface and stable overload performance further solidify its value for long-term critical power protection.

Product Features
Built-In Isolation Transformer
Integrates a dedicated isolation transformer to deliver stable voltage regulation and strengthen electrical isolation. It effectively shields sensitive equipment (like medical devices and precision servers) from electrical disturbances, harmonic interference, and ground loop issues, ensuring consistent power quality.
Customizable Scalable Design
Offers modular capacity from 20kVA to 60kVA with integrated cabinet installation for space efficiency. For systems exceeding 60kVA, it supports configuration with independent transformer cabinets to match large-scale power demands. Hot-swappable modules enable hassle-free capacity upgrades without downtime.
Reliable Performance & Overload Protection
Adopts a three-in-three-out architecture and advanced DSP control for stable operation. It handles 110% overload for 60 minutes and 150% overload for 1 minute, with THDi < 3% to ensure clean power. Even in harsh grid conditions, it maintains consistent output to protect critical loads.
Intelligent Monitoring & Battery Management
Equipped with an LCD LED display for real-time tracking of system status, load rate, and transformer temperature. Supports RS232, RS485, SNMP, and dry contact interfaces for remote management. It also features advanced battery management (supporting ±240VDC configuration) to extend backup power life.
