Introduction CONSNANT officially releases the brand-new CNG112 Series 4~20KVA Low Frequency Online UPS, optimized for single-phase critical power demand across global IT rooms, industrial automation, commercial office and small-scale data center projects. As an upgraded single-in single-out Low Frequency UPS, CNG112 integrates built-in isolation transformer, full-circuit protection and intelligent monitoring, delivering stable, clean backup power for precision electronic equipment in unstable grid environments worldwide.   Core Product Advantages of CNG112 4-20KVA Low Frequency UPS 1. Industrial Low-Frequency Transformer Design Equipped with internal isolation transformer as standard configuration, the CNG112 series features outstanding anti-surge and anti-interference performance, effectively filtering grid harmonic, voltage spike and waveform distortion. It remains stable in regions with poor power quality, a core advantage compared with conventional high-frequency UPS for harsh grid overseas projects. 2. Comprehensive Multi-layer Load Protection Complete protection mechanism including overvoltage, undervoltage, overload, short-circuit, over-temperature and lightning surge protection. When abnormal grid fluctuation or sudden blackout happens, the UPS instantly switches to battery mode to avoid unexpected shutdown and hardware damage of servers, PLC control hosts and monitoring equipment. 3. Optimized Battery Management System Customized charging algorithm for lead-acid storage batteries, realizing floating charge & equalized charge automatic switching, reducing overcharging damage and prolonging the whole battery service life. Flexible external battery configuration supports customizable backup runtime from tens of minutes to several hours to match diverse client project demands. 4. Intelligent Human-Machine & Remote Management Large LCD real-time display for input voltage, output parameter, battery status and fault code, facilitating on-site inspection and daily maintenance. Optional SNMP/RS485 communication module enables remote centralized monitoring via PC or cloud platform, ideal for centralized management of multi-set UPS deployed in branch office or distributed IT rooms. 5. Compact Mobile Cabinet Structure Equipped with wear-resistant universal casters, the vertical compact cabinet is easy for transportation, site placement and layout adjustment, saving installation space for narrow equipment room and small control cabinet scenarios.   Wide Application Scenarios of CNG112 Series The 4KVA~20KVA full power range covers diversified critical load fields: ✅ Small & medium-sized IDC computer room, server workstation and network equipment ✅ Industrial automation control system, PLC cabinet and production monitoring equipment ✅ Hospital outpatient office, banking terminal and retail commercial POS system ✅ Government office building, security monitoring and communication terminal equipment Perfectly fit overseas small-scale engineering bidding, system integrator matching and end-user facility renovation projects across Southeast Asia, Middle East, Africa and other emerging markets with unstable local power supply.   Why Choose CONSNANT CNG112 Low Frequency UPS?
