Design and Build: Built for Enterprise Durability
The SUVTP30KH4B4S’s tower configuration prioritizes accessibility and stability, with a substantial 59-inch height that fits under raised floors or in dedicated UPS rooms. Its 20.6-inch width and 33.1-inch depth offer a compact footprint for its class, but the 1,256-pound weight—bolstered by four integrated battery modules—necessitates bolt-down brackets and professional setup to handle seismic or relocation stresses. The steel enclosure features front-access panels for easy servicing, and the modular battery string allows hot-swaps without load disruption.
A front LCD console delivers real-time diagnostics, while audible alarms at 55 dB alert users to issues. Dual-mains inputs and screw terminals simplify wiring, and the internal bypass chassis supports seamless utility passthrough. Overall, it’s a fortress-like build tailored for 24/7 reliability in data centers or factories.
Standout Features That Ensure High Availability
This UPS excels with enterprise-focused innovations for redundancy and oversight:
- Double-Conversion Online Topology: Continuously conditions power, isolating loads from grid noise, surges, or sags with <5% distortion—ideal for PFC-corrected equipment.
- Scalable Runtime and Parallelism: Four VRLA modules provide baseline extension; add more for longer autonomy or parallel up to four units for N+1 redundancy and load sharing.
- Internal Maintenance Bypass: Enables service or overload handling without interrupting power, achieving near-100% uptime.
- Advanced Monitoring Suite: The pre-installed AP9619 card supports SNMP, web-based remote access, and environmental sensors; pair with PowerChute for automated responses.
- Hot-Swappable Batteries: Replace modules on-the-fly, with 3–5 year expectancy under optimized charging.
- Included Start-Up Service: 5×8 professional installation ensures optimal deployment.
These elements make it a scalable guardian for critical infrastructure.
Performance in Action
Deployed in real-world tests, the SUVTP30KH4B4S handles 24kW full loads with ~5 minutes of runtime, extending to 16 minutes at half capacity—scalable via extras for outage bridging. Its 96.4% efficiency curbs operating costs, and wide frequency tolerance (40–70 Hz) accommodates generators seamlessly. Voltage regulation keeps output stable during brownouts, with users noting flawless parallel syncing for distributed power.
Recharge is efficient at 5 hours, and the 55 dB operation blends into noisy environments. In industrial and IT scenarios, it has powered through multi-minute outages without glitches, validating its role in 99.999% availability targets.
Ideal Applications: Tailored for Three-Phase Demands
The SUVTP30KH4B4S shines in high-stakes, three-phase contexts:
- Data Centers: Safeguards servers, storage, and networks with redundant scalability.
- Large Retail and Offices: Protects POS, HVAC, and IT during peak operations.
- Industrial Facilities: Powers machinery and controls against voltage dips.
- Healthcare Settings: Ensures uninterrupted medical and diagnostic equipment.
It’s a legacy powerhouse for any 30kVA three-phase need.
