In today’s technology-driven world, uninterrupted power is not just a luxury—it’s a necessity. Whether you’re managing a server room, a network closet, or critical IT infrastructure, power disruptions can lead to costly downtime, data loss, or equipment damage. That’s where the APC 6000VA Double Conversion Smart-UPS SRT 230V (SRT6KXLI) comes in. Designed by Schneider Electric’s APC brand, this uninterruptible power supply (UPS) offers robust, reliable, and efficient power protection for a wide range of applications. Let’s dive into what makes this UPS a standout choice for businesses and IT professionals.
What is the APC Smart-UPS SRT 6000VA (SRT6KXLI)?
The APC Smart-UPS SRT 6000VA (model SRT6KXLI) is a high-performance, double-conversion online UPS with a power capacity of 6000VA (6kVA) or 6000 watts (6kW). Operating at a nominal input and output voltage of 230V, it’s tailored for environments requiring consistent, clean power delivery. This tower-configurable UPS is part of APC’s Smart-UPS On-Line series, renowned for its advanced features, scalability, and reliability.
Unlike line-interactive UPS systems that switch to battery power only during outages, a double-conversion UPS continuously converts incoming AC power to DC and back to AC. This process ensures a stable, pure sine wave output, free from fluctuations, surges, or noise—ideal for sensitive electronics like servers, medical equipment, and industrial systems.
Key Features of the SRT6KXLI
- Double-Conversion Topology
The SRT6KXLI’s double-conversion design provides zero transfer time to battery power during outages, ensuring seamless operation for critical loads. It also regulates voltage and frequency, protecting equipment from power irregularities without draining the battery unnecessarily. - Scalable Runtime
Need more backup time? The SRT6KXLI supports up to 10 external battery packs (e.g., SRT192BP), allowing you to extend runtime based on your specific needs. This scalability makes it a flexible solution for growing businesses or applications with varying power demands. - High Efficiency with ECO Mode
While double-conversion UPS systems are known for their reliability, they can consume more energy. The SRT6KXLI counters this with an ECO Mode, bypassing unused electrical components during stable power conditions to boost efficiency without compromising protection. - Advanced Management Capabilities
Equipped with a Network Management Card and SmartSlot, this UPS offers remote monitoring and control via Ethernet, USB, or serial connections. It integrates with APC’s PowerChute Network Shutdown software, enabling safe system shutdowns and centralized management through platforms like EcoStruxure IT. - Intuitive LCD Display
The SRT6KXLI features a clear, graphical LCD interface that provides real-time insights into system status, power conditions, and alarms. This user-friendly design simplifies monitoring and troubleshooting. - Hot-Swappable Batteries
Downtime for maintenance is minimized thanks to hot-swappable, maintenance-free sealed lead-acid batteries. You can replace them without powering down the UPS, ensuring continuous operation. - Robust Output Connections
The UPS includes multiple output options:- 6x IEC 320 C13 outlets
- 4x IEC 320 C19 outlets
- 1x Hard Wire 3-wire (H N + G) connection
- 2x IEC Jumpers
These versatile connections support a variety of devices, from servers to networking equipment.
- Compact and Convertible Design
While it ships as a tower unit, the SRT6KXLI can be converted to a rack-mount configuration with an optional rail kit (SRTRK2 or SRTRK3). Measuring 432 mm (H) x 174 mm (W) x 719 mm (D) and weighing 60 kg, it’s compact yet powerful.
