Design and Build: Engineered for Durability and Scalability
The SUVTP40KH4B4S adopts a robust tower form factor, standing at nearly 5 feet tall with a compact 20.6-inch width—ideal for space-constrained server rooms or industrial floors. Its black steel enclosure is built to last, supporting front-access mounting and bolt-down brackets for seismic stability. At over 1,300 pounds, it demands professional installation, but the modular design shines: power and battery modules ship pre-installed, with no free slots initially but room for parallel expansion.
Dual-mains input and built-in static/maintenance bypasses enable seamless transfers, while the VRLA batteries are hot-swappable for zero-downtime swaps. Grounded terminals and screw connections ensure safe wiring, and the unit’s non-rack-mountable yet two-post adaptable structure fits diverse setups. Overall, it’s a tank-like build prioritizing longevity in 24/7 operations.
Standout Features That Deliver Enterprise Reliability
This UPS elevates basic protection with intelligent, redundant capabilities:
- Double-Conversion Online Topology: Provides continuous conditioning for clean, stable power with zero transfer time—essential for sensitive three-phase loads like motors and IT gear.
- Scalable Runtime and Redundancy: Starts with four VRLA modules for baseline extension; add more or parallel up to four units for N+1 redundancy and hours of runtime.
- Integrated Bypass System: Internal maintenance and static bypasses allow service without load interruption, boosting availability to 99.999%.
- Advanced Monitoring: Pre-loaded Network Management Card enables remote SNMP access, environmental sensors, and prioritized alarms—pair with EcoStruxure IT for full oversight.
- Efficiency and Sustainability: Achieves high input power factor (0.98) for energy savings; supports Schneider’s circularity initiatives like take-back and remanufacturing.
- User-Friendly Service: Includes 5×8 start-up, audible/visible alarms, and EPO for safety, with a 3–5 year battery expectancy under temperature-compensated charging.
These features make it a proactive shield against power anomalies.
Performance in Action
In practice, the SUVTP40KH4B4S excels at handling full 32kW loads with ~5.5 minutes of runtime on internal batteries, extending significantly with additions—up to 20+ minutes at half load per module. Its wide input range (304–477V) manages fluctuations effortlessly, while the pure sine wave output (<5% THD) prevents issues in PFC-corrected equipment. Users in data centers report flawless parallel operation for load sharing, with the 55 dBA fan noise tolerable in noisy environments.
Recharge is efficient at 5 hours via a 1,985W charger, and efficiency graphs (available via APC tools) show peaks near 95% in online mode. In real outages, it has sustained manufacturing lines and colocation facilities through brownouts, underscoring its role in achieving high uptime SLAs.
Ideal Applications: Powering High-Stakes Three-Phase Setups
Tailored for robust three-phase needs, the SUVTP40KH4B4S fits:
- Data Centers: Protects rack servers and storage with scalable redundancy.
- Industrial Facilities: Shields PLCs, motors, and automation from surges.
- Healthcare: Ensures continuous power for MRI machines and life-support systems.
- Telecom Hubs: Maintains switches and base stations during grid instability.
- Commercial Buildings: Backs HVAC and lighting in offices or retail.
It’s a strong legacy choice for 40kVA three-phase demands.
