APC SY125K250D Symmetra PX 125KW Scalable to 250KW without Maintenance Bypass or Distribution-Parallel Capable

Deliver continuous, enterprise-grade power where uptime matters most. The APC by Schneider Electric Symmetra PX is a modular, double-conversion online UPS engineered for data centers, security rooms and mission-critical monitoring and surveillance applications. Designed as a scalable power train, the SY125K250D starts at 125 kW and can grow to 250 kW without a maintenance bypass, letting you expand capacity without disrupting protected loads. Its hot-swappable power and battery modules, built-in self-diagnostics and SNMP management reduce mean time to repair and lower the risk of human error. With VRLA battery support, a 3.5-hour recharge and run times of approximately 6 minutes at full load (18 minutes at half load), the Symmetra PX ensures orderly generator handoff and continuous operation during outages. Environmentally certified and engineered for high-density deployments, this UPS protects critical infrastructure across networking, security and surveillance systems. Contact our sales team to configure the Symmetra PX for your data center, security operations center or distributed monitoring deployment.
