The 120kVA Uninterruptible Power Supply (UPS) delivers ultimate electrical power protection for highly critical and large-scale infrastructures. Featuring a high-performance transformer-free 3-level IGBT topology and Full Digital Control, it guarantees an ultra-high efficiency of up to 96.5% in double-conversion mode. With a Unity Power Factor (1.0), it delivers a full 120kW of continuous power output without de-rating. Engineered to handle highly complex non-linear industrial loads, severe grid voltage fluctuations, and frequent outages, it completely isolates medical equipment, telecom centers, and automated manufacturing units from power failures.
Smart Loop/Easy Test System: Allows complete performance verification testing under full load capacity without needing a real load bank.
Advanced Battery Intelligence: Compatible with conventional heavy VRLA systems as well as modern Lithium-ion battery cabinets.
Robust Fault Isolation: Includes dry contact triggers for emergency power off (EPO), backfeed loop defense, and smart shunt-trips.
Next-Gen Monitoring: Smart touch-screen color LCD interface with optional Modbus and SNMP agent cards for continuous remote web access.
