APC SRTG20KXLI – Smart-UPS RT 20kVA 3-Phase Online Double Conversion UPS

Overview :

The APC SRTG20KXLI is a high-density, double-conversion online UPS designed to provide high-availability power protection for mission-critical infrastructure. Engineered for versatility, this 20kVA/20kW unit features unity power factor, ensuring that the volt-ampere rating matches the wattage to support modern, power-dense servers and networking equipment without derating. It is primarily deployed in mid-to-large data centers, medical facilities, and industrial edge environments where power quality is non-negotiable.

The SRTG20KXLI supports both 3:1 and 3:3 phase configurations, allowing it to integrate seamlessly into various electrical architectures. Its online topology ensures zero transfer time to battery, protecting sensitive loads from surges, spikes, and total power failure. For remote management, the unit comes equipped with an integrated Network Management Card (NMC), providing secure monitoring and control via web browser, CLI, or SNMP. The system is designed for high efficiency, featuring a “Green Mode” that achieves up to 98% efficiency by bypassing unused electrical components in stable power conditions, significantly reducing cooling costs and total cost of ownership (TCO).

Frequently Asked Questions :

Can the SRTG20KXLI be configured for single-phase output?

Yes, the unit is flexible and can be hardwired for either 3-phase input to 3-phase output (3:3) or 3-phase input to 1-phase output (3:1) depending on your site requirements.

Does this model include the rack-mounting hardware?

Yes, the SRTG20KXLI is a rack/tower convertible model and includes the necessary rail kits and hardware for a 9U rack installation.

Is the network management card sold separately?

No, this specific model includes an integrated Network Management Card (NMC) pre-installed, allowing for immediate remote monitoring and graceful shutdown capabilities.

What is the benefit of Unity Power Factor in this UPS?

Unity Power Factor (1.0) means the kVA rating equals the Wattage (20kVA = 20kW). This allows you to support more modern servers that have power factor corrected power supplies without needing to oversize the UPS.
