APC SRT5KRMXLT-IEC 5,000 VA 208 V Smart-UPS | Rack-Mount Online

Protect high-value infrastructure with a UPS built for sustained business continuity. The APC Smart-UPS SRT 5,000VA 208V RM IEC is an online, rack-mountable UPS designed for environments where power quality and runtime directly affect service availability. With 5,000 VA and 4,250 W capacity, it is sized for heavier IT loads that outgrow smaller units and need more headroom for servers, storage, and network aggregation equipment. This model delivers pure sine wave output, which is important for active power-factor-corrected power supplies and other sensitive electronics that perform best on clean utility-grade power. The 3U rack form factor helps preserve rack space while still supporting serious load capacity. A 4-minute full-load runtime gives teams time to ride through short outages, complete graceful shutdowns, or bridge to generator power. For infrastructure teams comparing lower-tier UPS options, this unit justifies its position by combining capacity, runtime, and rack efficiency in one platform. It is a strong fit where downtime is expensive, electrical environments are demanding, and the load profile requires more than basic battery backup.
