APC SY125K250D-NB Symmetra PX 125kW Scalable to 250kW without Bypass

Protect critical infrastructure and security systems with the APC by Schneider Electric Symmetra PX double-conversion online UPS — engineered for mission-critical data centers, security, surveillance and monitoring environments. This modular UPS starts at 125kW and can scale to 250kW without bypass, giving you predictable capacity growth and simplified deployments. The Symmetra PX combines redundant power, intelligence and external battery systems so you can extend runtime or replace modules without disrupting protected loads. Built for three-phase environments with selectable 400V/480V output and a 2 millisecond transfer time, it delivers continuous, clean power to sensitive servers, network switches, and surveillance recorders. SNMP manageability enables proactive monitoring and integration with your NMS or security management consoles. Its serviceable, hot-swappable design reduces onsite technician time and lowers operational risk, while Energy Star and Green Premium certifications support sustainability initiatives. Ideal for small-to-medium data centers or dedicated security zones in larger facilities — contact your APC by Schneider Electric representative to configure a Symmetra PX for your data center, monitoring, or surveillance deployment.
