Rack-mounted UPS from 1-60kVA with double-conversion technology, pure sine wave output, 98.5% ECO efficiency, and parallel redundancy for critical IT loads.
The ZT-HR Series is a rack-mountable Uninterruptible Power Supply (UPS) engineered to deliver high-reliability power protection for mission-critical servers, storage, and network equipment in data centers, edge computing sites, and enterprise IT rooms. Utilizing advanced online double-conversion technology, it provides pure sine wave output with zero transfer time between mains and battery, effectively isolating connected loads from grid disturbances such as surges, sags, and harmonics. Covering a broad power range from 1kVA to 60kVA, the series offers flexible configurations including single-phase and three-phase models to suit diverse deployment scenarios. Its high-efficiency ECO mode achieves up to 98.5% efficiency, significantly reducing energy costs and supporting green data center initiatives. Models of 10kVA and above support parallel operation of up to 4 units for N+X redundancy or capacity expansion. The standard rack-mount form factor (2U/3U/4U) simplifies installation within standard 19-inch cabinets, while the intelligent LCD/LED display provides real-time status monitoring. With wide input voltage tolerance, generator compatibility, and optional SNMP for remote management, the ZT-HR Series ensures business continuity for your critical infrastructure.
