In today’s digital economy, system downtime is simply not an option. Whether you’re running financial services, government data platforms, medical equipment, or edge computing environments, uninterrupted power is the backbone of operational reliability.
That’s where the GT33 Rack Online UPS Power Supply from GOTTOGPOWER comes in—a robust, compact, and high-performance solution designed to meet the demands of modern infrastructure.
Built for High-Density, Mission-Critical Environments
The GT33 series offers a wide power range (10/15/20/30/40kVA) and can be flexibly deployed in rack-mounted or tower formats. With a high power density of 30kW in just 3U, it maximizes valuable rack space—ideal for data centers, network rooms, and modular IT cabinets.
Its flexibility in configuration (3P/3P, 3P/1P, 1P/1P) ensures seamless integration across diverse application scenarios, including:
- Government and finance institutions
- Educational and medical facilities
- Energy, transportation, and broadcasting networks
Core Performance Advantages
· Pure and Stable Output for Sensitive Loads
The GT33 rack online UPS is engineered to deliver pure, uninterrupted sine wave output with exceptional precision. Voltage is regulated within ±1%, while frequency stability is maintained at ±0.1%, ensuring an ultra-consistent power supply. This level of accuracy minimizes electrical noise and protects mission-critical equipment from fluctuations. With extremely low Total Harmonic Distortion (THDu)—less than 1% for linear loads and less than 5% for non-linear loads—the GT33 rack online ups guarantees clean power delivery for sensitive IT systems, industrial control units, medical imaging devices, and communication infrastructure.
· Extreme Overload Handling
Unpredictable power demands or transition periods can pose serious threats to continuity. The GT33 rack online ups is designed with robust overload capabilities to handle these situations without disruption:
- 110% load for up to 1 hour
- 125% load for up to 10 minutes
- 150% load for up to 1 minute
These figures ensure the UPS can maintain performance even during brief overloads, giving mission-critical systems ample buffer before backup systems engage or corrective action is taken.
· Superior Power Adaptability
The GT33 rack online ups significantly reduces stress on your electrical infrastructure. With an input power factor exceeding 0.99 and an input THDi of less than 3%, it minimizes harmonic interference and maximizes energy efficiency. This results in reduced energy waste, enhanced generator compatibility, and extended upstream equipment lifespan. For facilities running on backup generators or renewable sources, this superior adaptability translates into smoother integration and reduced risk of power quality issues.
· Next-Gen Intelligent Battery Management
The UPS features an advanced battery management system designed to extend battery life, increase safety, and enable predictive maintenance. Precision charging is maintained at ±1% voltage accuracy, reducing overcharge or undercharge risks. Operating at a high 240VDC level, the battery system improves energy density and efficiency. With real-time battery diagnostics, the system can proactively alert users to potential failures, helping reduce unexpected downtime and service costs.
· IoT-Enabled User Interaction and Expansion
Control, monitor, and optimize your UPS system through a vibrant 7-inch full-color touchscreen interface. The GT33 rack online ups integrates seamlessly into modern infrastructures with built-in IoT functionality and a comprehensive array of communication interfaces—USB, RS232, RS485, and dry contact ports—allowing real-time status updates, alarms, and remote management capabilities.
For growing or complex environments, a range of optional modules supports enhanced scalability and customization:
- SNMP cards for network-based monitoring
- AS400 cards for compatibility with legacy systems
- Parallel kits for load-sharing redundancy
- Cold start modules for battery-only startup during power outages
- Dust filters and environmental protection accessories
Together, these features make the GT33 rack online ups a versatile, intelligent, and future-ready solution for safeguarding power continuity in the most demanding settings.
