Uninterruptible power supply Unit UD3000CS-IRTG2 3000VA rack/tower

Unit UD3000CS-IRTG2 is an offline (standby) uninterruptible power supply delivering 3000VA of backup power in a convertible rack/tower enclosure. Designed to protect equipment from mains interruptions, voltage dips and spikes, this UPS provides short-term battery support and automatic transfer to battery power during outages. The compact form factor and selectable mounting options make it adaptable for server cabinets, office racks or standalone placement near network or workstation equipment.

Advantages

The UPS offers 3000VA capacity for supporting small servers, network devices and workstations with reliable short-duration backup. As an offline topology device it provides fast transfer to battery power and basic surge protection without complex configuration. The convertible rack/tower design allows flexible installation in cabinets or on floors, while the included interfaces enable monitoring and safe shutdown of connected equipment. Physical indicators and straightforward controls simplify everyday operation and status checks.

Suitable for

• Small office servers and NAS units
• Network switches, routers and firewalls
• Workstations and point-of-sale systems
• VoIP gateways and communication devices
• Environments requiring short-term runtime for graceful shutdown

Key specifications

• Topology: Offline (standby) UPS
• Rated capacity: 3000 VA
• Form factor: Convertible rack/tower enclosure
• Output waveform: Simulated sine wave (typical for standby UPS)
• Automatic transfer to battery on mains failure
• Front-panel indicators and control buttons for status and management
• Multiple outlet types for connecting servers, network and workstation equipment

How to use

Install the UD3000CS-IRTG2 in the chosen configuration—mount in a 19-inch rack or position as a tower—ensuring adequate ventilation space. Connect equipment to the UPS outlets and plug the UPS into a reliable mains outlet. Charge the internal battery fully before relying on the unit for backup. On mains failure the UPS will switch to battery power automatically; monitor the front-panel indicators and, if available, use monitoring software or signaling interfaces to perform an orderly shutdown of critical systems when battery capacity becomes low.

Recommendations

For optimal reliability, verify connected load does not exceed the rated capacity, perform periodic battery self-tests, and replace batteries according to the manufacturer’s recommended service interval. Use the convertible mounting option that best suits your rack space and ventilation needs, and connect essential equipment only to battery-backed outlets while noncritical loads can be placed on surge-only outlets if provided.
