Operation mode：Three-Phase +N+G
Application area：
Intelligent digital control technology: using high-speed microcontrollers and programmable logic devices to achieve circuit control, parameter setting, operation management, advanced self-test and self-detection functions, all independent circuit connections on the board can be self-contained Inspection and failure analysis, you can fully rely on digitally converted sine wave voltage, and a new program that works perfectly: to meet your actual needs.
High-efficiency IGBT (Insulated Gate Bipolar Transistor) inverter technology: good high-speed switching characteristics of IGBT; high-voltage and high-current operating characteristics; voltage-driven, requiring only a small control power. The fifth-generation IGBTs have a lower saturation voltage drop, and the inverters work more efficiently and with higher reliability.
Flexible parallel technology: suitable for single-machine, 1+1 parallel, N+1 parallel redundancy of different loads.
Superior load characteristics: Three-phase fully independent PWM modulation, full-bridge IGBTM inverter technology, fully meets the transition from 0 to 100% load without switching to bypass and protecting the output stable and reliable.
User-friendly large-screen LCD Chinese display (optional touch screen): large-screen Chinese-English menu, visual display of flow chart operation status, flexible realization of human-machine dialogue function, touch screen with event record display, medium comparison = English Optional menu operation.
Perfect protection functions: input and output over-voltage protection, input surge protection, phase sequence protection, battery over-charge and over-discharge protection, output overload short-circuit protection, over temperature protection and other system protection and alarm functions.
High-performance dynamic characteristics: It adopts various feedback controls such as instantaneous control mode and RMS to achieve high dynamic adjustment and reduce voltage distortion.
The 6-pulse (optional 12-pulse) rectifier charger is used to simultaneously increase the input harmonic filter: effectively suppress the input harmonic pollution, increase the input power factor of the UPS power supply, and reduce the input harmonic current.
Intelligent battery management: intelligent battery charging, automatically adjust the battery charging parameters according to the user's battery configuration, and will charge the battery according to the power supply environment, floating charge conversion, temperature compensation charging, discharge management, extend battery life, reduce management The burden of the staff.
Complete isolation technology: input. Output is completely isolated, reducing harmonic current and direct interference from mains.
Intelligent communication management: RS232 and RS485 communication ports truly realize multi-purpose communication and remote monitoring, optional SNMP card, realize remote monitoring and network management, optional dry contact interface, and use passive contacts to realize UPS status monitoring.
