Standout Features That Set It Apart
The Smart-UPS VT series redefines three-phase protection with user-centric design, drawing from APC’s legacy of reliability. The SUVTP40KH4B4S excels in modularity and intelligence, minimizing downtime in real-world scenarios. Key highlights:
1. Modular, Hot-Swappable Design for Effortless Maintenance
Shipped with four battery modules pre-installed, this UPS allows tool-less swaps and expansions up to 10 modules without interrupting loads—ideal for 24/7 operations. The modular architecture speeds repairs and testing, reducing mean time to repair (MTTR) significantly.
2. Automatic and Internal Maintenance Bypass
In overload or fault scenarios, the built-in automatic internal bypass seamlessly routes utility power to loads, ensuring continuity. The maintenance bypass enables safe servicing without powering down, a boon for data centers where every minute counts.
3. Parallel Capacity for Scalable Redundancy
Link up to eight units in parallel to boost total capacity to 320kVA or achieve N+1 redundancy, perfect for growing enterprises. Dual mains input supports two separate power sources, enhancing availability in generator-backed setups.
4. Intelligent Battery Management and Monitoring
Precision charging optimizes battery life (3-5 years typical), while embedded sensors provide real-time health metrics. The alpha-numeric LCD, LED indicators, and audible alarms offer instant status updates, with RS-232/SmartSlot ports enabling integration with PowerChute or InfraStruXure Manager for remote oversight.
5. High-Efficiency Online Topology with Clean Power
Double-conversion delivers zero-transfer-time protection against surges, sags, and harmonics (<3% THD), with programmable frequency for global compatibility. ECO mode can push efficiency beyond 98% during stable conditions, cutting energy costs.
Who Should Consider the APC Smart-UPS VT 40kVA 400V?
This powerhouse suits medium data centers powering 20-30 racks (10-20 minutes runtime at half load), large retail outlets with POS and HVAC systems, or regional offices with dense IT. It’s generator-compatible for hybrid resilience and shines in emerging markets with grid instability. For smaller scales, the 20kVA VT variant fits; hyperscalers might parallel multiples for massive redundancy.
Why Choose APC Smart-UPS VT 40kVA 400V in 2025?
As AI and edge demands surge power needs, the SUVTP40KH4B4S offers modular might and APC’s ecosystem for future-proof protection. It’s more than a UPS—it’s scalable continuity.
