APC Smart-UPS On-Line SRT1000RMXLI-NC - 1kW/VA, 6x C13 output, rackmount, NMC

**Summary** The APC Smart-UPS On-Line SRT1000RMXLI-NC is a professional-grade, 1kVA/1kW double-conversion rackmount UPS designed to provide clean, uninterrupted power to critical IT infrastructure. By utilizing always-on double-conversion technology, it eliminates the transfer time typically associated with switching to battery power, ensuring that sensitive hardware like servers, switches, and storage devices remain stable during electrical disturbances. Featuring a pre-installed Network Management Card, this unit allows for sophisticated remote monitoring, controlled shutdowns, and efficient power management in complex business environments. **Buying Advice** This unit is specifically engineered for IT professionals, network administrators, and small-to-medium business environments where uptime is non-negotiable. It is the ideal choice if you require zero-transfer power protection for sensitive, mission-critical hardware. Because it is a rackmount unit (2U), it is best suited for organizations already utilizing server rack enclosures. It is also a sound investment for those looking to future-proof their setup, as the runtime can be extended with external battery packs and the switched outlet groups allow for granular control over power consumption and phased start-ups. **Pros** - **Double-Conversion Technology:** Provides continuous, perfectly clean sine-wave power, isolating connected equipment from all voltage fluctuations and power irregularities. - **Advanced Network Management:** Includes a pre-installed Network Management Card (AP9641) for SNMP-based remote management and automated server shutdown via PowerChute software. - **Modular Maintenance:** Features user-replaceable, hot-swappable batteries, allowing you to maintain the unit’s lifespan without powering down your critical equipment. - **Configurable Power Delivery:** Switched outlet groups enable remote reboots of specific hardware and phased power-up sequences to manage peak loads effectively. **Cons** - **Weight and Form Factor:** At 21kg and 2U height, it requires a sturdy rack environment and careful installation planning. - **Complexity for Beginners:** The wealth of management features and configuration options (like virtual machine integration) may be excessive for home or basic office users. **FAQ for this product** **Q: Can I replace the battery without turning off my connected server?** A: Yes, the unit is designed with a hot-swappable internal battery cartridge (APCRBC155), allowing you to replace the battery safely while your equipment remains online. **Q: Can this UPS be used with an emergency generator?** A: Absolutely. The double-conversion technology makes this UPS fully compatible with emergency generators, ensuring that the power supplied to your equipment remains stable and clean even when switching between utility and generator sources. **Q: Is it possible to extend the runtime beyond the standard battery capacity?** A: Yes, you can significantly increase the emergency runtime by connecting external battery packs (model SRT48RMBP) to the unit. **Value Score** 9/10: This is a robust, highly reliable enterprise-grade solution that justifies its value through superior power conditioning, extensive remote management capabilities, and a modular design that facilitates a long service life.
