The low-frequency transformer-based design provides strong electrical isolation and excellent overload and transient-load handling. This makes the UPS suitable for critical IT environments where power reliability is essential.
Key advantages include:
- 120KVA rated capacity for centralized critical-load protection
- Online double-conversion technology for continuous power conditioning
- Low-frequency transformer design for enhanced isolation and reliability
- Stable output voltage and frequency
- Protection against power outages, voltage fluctuations, surges, and electrical disturbances
- Strong overload and short-circuit protection
- Expandable battery capacity for different backup-time requirements
- LCD monitoring and optional RS485, USB, or SNMP communication
- Suitable for server rooms, data centers, network rooms, and telecommunications facilities
For a server room or small-to-medium data center, the 120KVA UPS system can serve as the centralized backup power source for critical IT loads. When utility power fails, the UPS immediately supplies power from the battery system, allowing servers and network equipment to continue operating without an interruption that would normally cause a shutdown.
The backup time can be configured according to the required load and battery capacity. External battery cabinets can also be used when longer runtime is required.
A 120KVA UPS for a server room is suitable for applications requiring reliable power protection and centralized backup. It can protect critical equipment such as servers, storage, network switches, firewalls, communication systems, and monitoring equipment.
For higher availability requirements, the UPS system can be integrated with a maintenance bypass, generator, intelligent monitoring system, and appropriate power distribution equipment.
