Designed for demanding industrial environments, ensuring continuous and stable operation of critical equipment during power failures, voltage fluctuations, and frequency anomalies.
Patented technology and international first-tier brand components ensure continuous operation in the harshest environments
Features heat dissipation technology with 100% front-side maintenance. Allows routine maintenance, periodic replacement of wearing parts, and inspection directly from the front door. Supports wall-mounted and side-by-side installation.
Equipped with graphene coating technology and specially selected components. With high static pressure fans, it effectively dissipates heat in high-temperature, high-humidity, and dusty environments without air conditioning.
Standard IP31 rating, with optional IP32, IP41, IP42 for harsher environments. No derating required, supports wall-mounted side-by-side installation.
Critical power components feature redundant design. Control power supply redundancy and margin design on important components ensure continuous operation in harsh environments.
Temperature compensation technology automatically adjusts charging voltage to extend battery life. Battery trigger interface can forcibly disconnect battery in emergency situations to prevent secondary accidents.
Real-time power flow diagram, parameter settings, 2000 event logs, component life management system, battery remaining capacity/time display, fan and battery life warnings.
Real-time processing of input power eliminates voltage fluctuations, frequency deviations, and harmonic interference. Outputs stable pure sine wave for zero-interruption protection of precision equipment.
Supports 2-4 UPS units in parallel for redundancy or capacity expansion. Accepts dual independent mains inputs for dual-power supply systems, scalable up to 4 units horizontally.
LF Series UPS focuses on reliability, suitable for various critical fields
Manufacturing & control systems, industrial machinery, instrumentation, process monitoring & control, safety & transport systems
Data centers, hospitals, airports, semiconductors, water treatment, power plants, metallurgy
Oil & gas, petrochemical, mining
Military equipment, defense facilities
