What this product is
What this product is
The East EA890 series is a 10kVA to 120kVA 3-phase in/out heavy-duty low-frequency online double-conversion UPS, engineered with a built-in output galvanic isolation transformer and robust IGBT inverter to deliver pure, uninterrupted power under severe industrial electrical environments.
What problem it solves
The East EA890 10kVA-120kVA industrial-grade low-frequency online UPS is purpose-built to withstand severe grid fluctuations, lightning surges, and heavy inductive or capacitive load shocks. Featuring true double-conversion online topology with advanced DSP digital control, the unit integrates a rugged industrial-grade copper output isolation transformer that completely isolates DC offsets and neutral-to-ground noise. Encased in a reinforced industrial chassis with an isolated forced-air cooling duct, all sensitive electronic boards are treated with conformal coating. The EA890 supports up to 6 units in direct parallel redundancy, delivers exceptional 150% overload resilience, and features an intuitive touchscreen graphical display, ensuring continuous uptime for automation, medical, transport, and mission-critical enterprise infrastructure.
