With its compact footprint, modular architecture, and high efficiency, this UPS ensures your critical systems stay online during outages. In this blog, we’ll dive into its features, specifications, and why it’s a go-to solution for businesses prioritizing uptime.
What is the APC Smart-UPS VT SUVTP20KH4B4S?
The SUVTP20KH4B4S is a 20kVA (16kW) online double-conversion UPS tailored for 400V three-phase input and output, ideal for protecting high-density loads like servers, networking equipment, or production machinery. It comes with four hot-swappable battery modules (expandable to five), an internal maintenance bypass, and parallel capability for redundancy or capacity scaling. It includes a 5×8 start-up service for seamless deployment. This tower UPS is perfect for small to medium-sized facilities needing dependable power without compromise.
Key Features for Robust Protection
The SUVTP20KH4B4S combines reliability, flexibility, and smart management to meet enterprise demands. Here’s what makes it stand out:
- Scalable Runtime: Equipped with four 9Ah sealed lead-acid battery modules, it delivers ~10–12 minutes of runtime at full load, with the option to add a fifth module or external battery packs for extended backup.
- Dual Mains Input: Supports two independent power sources for failover, ensuring continuous operation during utility disruptions.
- Internal Maintenance Bypass: Enables maintenance or battery swaps without shutting down connected loads, minimizing downtime.
- Intelligent Battery Management: Monitors battery health, voltage, and temperature in real time, optimizing lifespan (up to 5–7 years) and predicting maintenance needs.
- Parallel Capability: Connect up to four units for N+1 redundancy or up to 80kVA capacity, supporting growing power needs.
- Advanced Monitoring: Features an LCD display, LED indicators, DB-9 RS-232 port, and SmartSlot for network management cards, compatible with APC’s PowerChute or EcoStruxure IT for remote oversight.
These features deliver near-perfect uptime (>99.999%), making it ideal for environments where every second counts.

Compatibility and Scalability: Future-Ready Design
The SUVTP20KH4B4S integrates seamlessly with APC’s ecosystem, supporting external battery packs (e.g., SUVTBPXR) for prolonged runtime and parallel kits for multi-unit configurations. It’s optimized for three-phase loads like rack servers, telecom equipment, or control systems up to 20kVA. For management, it pairs with PowerChute Network Shutdown or EcoStruxure IT for real-time monitoring. It’s not designed for single-phase applications—use APC’s power distribution units for rack integration. Keep firmware updated via APC’s support portal for optimal performance.
Installation and Maintenance: Simplified for Efficiency
APC’s 5×8 start-up service ensures professional setup, testing, and training. Installation steps include:
- Site Preparation: Secure a ventilated space with reinforced flooring for the 1,600 lbs unit; verify 400V 3-phase power availability.
- Wiring: Connect dual mains inputs and output to loads using terminal blocks. Install battery modules in rear bays.
- Activation: Power on, run self-tests via the LCD interface, and configure monitoring software for runtime calibration.
Maintenance is streamlined with hot-swappable batteries and an internal bypass, allowing service without load interruption. Annual diagnostics via software maintain peak performance, and modular components keep costs low. Replacement batteries (e.g., APC’s RBC kits) are widely available.
APC’s UPS Selector tool estimates ~10 minutes of runtime at 16kW with four modules, extending significantly with additional packs or lower loads.
Why Choose the SUVTP20KH4B4S? Benefits and Considerations
This UPS offers robust protection, with users reporting seamless failover and up to 40% runtime gains with expansions. Its high efficiency (up to 96%) reduces energy costs, and the modular design supports upgrades without replacing the entire system. Dual inputs and parallel capability ensure redundancy, potentially saving thousands in downtime losses.
Considerations include its significant weight, requiring professional handling, and the need for climate control (below 77°F) to maximize battery life. Lead-acid batteries are cost-effective but have a shorter lifespan than lithium options, which APC offers at a higher cost. It’s specific to three-phase setups, so confirm compatibility with your infrastructure.
Conclusion: Power Continuity for Critical Operations
The APC Smart-UPS VT 20kVA 400V (SUVTP20KH4B4S) is a reliable, scalable solution for businesses that demand uninterrupted power. Its blend of intelligent management, high efficiency, and modular design makes it ideal for small data centers or industrial applications. Explore pricing and availability @ TIACO TECHNOLOGIES.
