APC SY125K500D-NB Symmetra PX 125kW Scalable to 500kW

Protect critical infrastructure with enterprise-grade, scalable power: the APC by Schneider Electric Symmetra PX SY125K500D-NB is a double-conversion online UPS engineered to keep data centers, security systems and surveillance deployments running without interruption. Designed as a modular, redundant power train, the Symmetra PX lets you start at 125kW and expand to 500kW as capacity needs grow, while three-phase architecture and fast 2-millisecond transfer time ensure continuous, high-quality output for servers, storage, networking and physical security gear. Integrated SNMP manageability and self-diagnostic modules simplify monitoring and maintenance, reducing mean time to repair and human error. The tower UPS supports hard-wired 4- and 5-wire installations and aligns with APC InfraStruXure deployments for zone-based or full-room protection. With Energy Star and Green Premium certifications, Symmetra PX balances availability with efficiency. Ideal for mission-critical environments—data centers, NOC rooms, CCTV and access control systems—this UPS provides predictable scalability and serviceability.
