Description
Keep mission-critical servers and network gear online—even when the power goes out. The APC Symmetra RM SYH6K6RMT-TF3 delivers 6 kVA / 4.2 kW of true online, double-conversion protection in a compact 10U rack chassis. N+1 modular power and battery architecture lets you hot-swap modules for zero-downtime maintenance and effortless scalability in 2 kVA increments.
A factory-integrated 208 → 120 V step-down transformer with four NEMA L5-20R outlets makes it simple to power mixed-voltage racks, while dual L6-20R receptacles serve 208 V loads. With an embedded Network Management Card 2, real-time monitoring and graceful shutdown are just a click away.
