Why Choose the SUVTP20KH4B4S?
The SUVTP20KH4B4S is engineered for reliability, efficiency, and ease of management, making it a top choice for businesses with moderate to high power demands. Here are its key features and benefits:
1. High Availability with Redundancy
The double-conversion online topology delivers clean, consistent power by isolating connected equipment from utility power fluctuations, such as surges, sags, or outages. The dual mains input supports connection to two independent power sources, reducing the risk of downtime. Parallel capability allows multiple UPS units to operate together, enabling either increased capacity (up to 80kVA with four units) or N+1 redundancy for critical applications.
2. Scalable Runtime
With four pre-installed VRLA battery modules, the SUVTP20KH4B4S provides approximately 15 minutes of runtime at full load and 38 minutes at half load. Businesses can extend runtime by adding external battery enclosures (e.g., SUVTXR6B6S), with support for up to three additional battery packs. Hot-swappable batteries ensure zero-downtime maintenance, and parallel battery modules enhance availability through redundancy.
3. Intelligent Management and Monitoring
The pre-installed network management card (AP9619) enables remote monitoring and control via a web interface or SNMP, with compatibility for APC’s InfraStruXure Manager for centralized oversight. The UPS features a multi-function LCD display, audible alarms, and LED status indicators for real-time system updates. Automatic self-tests proactively identify battery issues, and the SmartSlot supports additional management cards for customized functionality.
4. Cost-Effective and Efficient Operation
The SUVTP20KH4B4S reduces installation and operating costs through input power factor correction, which minimizes the need for oversized generators or cabling. Temperature-compensated battery charging optimizes battery life by adjusting charge voltage based on ambient conditions. The built-in maintenance and static bypass eliminates the need for external bypass equipment, simplifying installation. Its modular design supports fast serviceability with field-replaceable components.
5. Commitment to Sustainability
Aligned with Schneider Electric’s Green Premium™ label, the SUVTP20KH4B4S complies with RoHS/REACH regulations and prioritizes low-CO2 materials. It is part of Schneider Electric’s global take-back program, promoting responsible recycling and circularity through the “Use Better, Use Longer, Use Again” initiative. The Product Environmental Profile provides transparency on its environmental impact, supporting eco-conscious business practices.
Applications of the SUVTP20KH4B4S
The SUVTP20KH4B4S is designed for environments with moderate to high power requirements. Its primary applications include:
