Manufactured by Schneider Electric, this UPS is part of the Smart-UPS VT series, renowned for its centralized power protection and adaptability.
The SUVTP20KH4B4S supports 400V three-phase input and output (configurable for 380V or 415V), ensuring compatibility with diverse electrical systems. Its modular design, scalable runtime, and remote management capabilities make it an efficient solution for protecting sensitive equipment from power outages, surges, and voltage fluctuations.
Key Features of the SUVTP20KH4B4S
1. Double-Conversion Online Topology
The SUVTP20KH4B4S employs double-conversion online technology, converting incoming AC power to DC and back to AC to deliver a clean sine wave with less than 5% voltage distortion at full load. This ensures stable power quality, safeguarding equipment from power disruptions.
2. Scalable Runtime
The UPS supports extended runtime with external battery modules (e.g., SUVTXR6B6S), allowing up to four battery strings for customized backup time. It provides approximately 46 minutes of runtime at half load (8kW) and 18 minutes at full load (16kW).
3. Hot-Swappable Batteries
Equipped with four VRLA battery modules, the UPS supports hot-swappable battery replacement, enabling maintenance without interrupting connected loads. This minimizes downtime and reduces Mean Time to Repair (MTTR).
4. Dual Mains Input
The dual mains input feature allows connection to two independent power sources, enhancing reliability by providing redundancy if the primary source fails.
5. Internal Maintenance Bypass
An integrated maintenance bypass delivers utility power to connected loads during UPS maintenance or overload conditions, eliminating the need for an external bypass switch and lowering installation costs.
6. Parallel Capability
The UPS supports parallel operation for capacity or redundancy, allowing multiple units to be connected to increase total power or provide N+1 redundancy for mission-critical applications.
7. Advanced Management and Monitoring
The SUVTP20KH4B4S includes a multi-function LCD console, DB-9 RS-232 port, Smart-Slot with a pre-installed network management card (AP9631), and Ethernet connectivity for remote monitoring. It integrates with APC’s InfraStruXure Manager for centralized management. Features like periodic battery self-tests, audible alarms, and LED status indicators provide real-time system health insights.
8. Energy Efficiency and Sustainability
With 95.7% efficiency at full load, the UPS minimizes energy waste. It carries Schneider Electric’s Green Premium™ label, ensuring environmental compliance and eligibility for take-back programs in select regions, supporting recyclability.
9. Modular Design
The modular design, with field-replaceable power and battery modules, enhances serviceability and reduces maintenance costs. The UPS ships with modules pre-installed, enabling pre-installation testing and faster deployment.
10. Input Power Factor Correction
Input power factor correction reduces installation costs by allowing the use of smaller generators and cabling, making it cost-effective for large-scale setups.
