DG990 G4 40KVA 120KVA

DG990 G4 40KVA 120KVA

Advanced dual-core DSP control technology and 3-level technology

The DG900 G4 Series (40 kVA – 120 kVA) UPS are a new generation of high performance UPS that uses advanced dual-core DSP control technology and 3-level technology.

  • Output power factor 1.0
  • High efficiency 96% doubling the energy saving rate
  • Dual input design, supporting independent bypass
  • Advanced digital and parallel technology, providing higher reliability than single systems
  • Compact internal layout,  small footprint

Features

High reliability
  • Advanced DSP (Digital signal processors) technology, rectifier, inverter and charging are all controlled by DSP , which effectively improves product performance and system reliability
  • Fan speed varies intelligently with the load rate and charging current, which can effectively reduce the noise impact of the whole machine on the surrounding environment and extend the service life of the fan
  • Effective software and hardware protection function – integrates AC input overvoltage/under voltage, overload, short-circuit protection, overtemperature protection, IGBT pulse-by-pulse current limiting protection, battery under voltage warning protection, battery overcharge protection and other multi-functional protection in one, and has a strong self-diagnosis function, ensuring the stability and reliability of the system operation
  • Process optimisation – with three anti-paint process, UPS can work in a harsh environment for a long time
  • Advanced digital parallel technology, redundant parallel connection provide higher reliability than stand-alone systems
High usability
  • LCD screen + LED display: visually display UPS working status and operating parameters
  • Powerful background software
  • Compact internal layout, miniaturized complete unit for small footprint
High availability
  • Wide input range
  • Dual-input design to support independent bypass and improve bypass availability
  • High output power factor improved from 0.9 to 1, load capacity increased by 11%
  • Flexible configuration of number of batteries – supports 15~23 (30~46) pcs batteries
  • Two modes of frequency conversion: 50/60Hz output or 60/50Hz output to meet the special needs of users
High intelligence
  • Supports RS232, USB, NET, RS485, CAN, SNMP card, WIFI card, GPRS card and 4G card and other communication interfaces to monitor the running status of UPS. After configuring the WIFI card, GPRS card and 4G card, the UPS can be monitored in real-time via a mobile app
  • Intelligent battery management that allows regular battery self-test function
Energy conservation and environment protection
  • Active power factor correction – Adopting digital controlled active power factor correction (PFC) technology, the input power factor is up to more than 0.99, avoiding pollution to the grid environment, achieving energy saving and reducing the cost of system investment
  • System efficiency increased to 96% and energy saving rate doubled
  • When the power grid is in good condition, the working efficiency is up to 98% with high efficiency and energy saving after the ECO mode is started. In ECO working mode, a 120 kVA UPS full-load work can save 16556 CNY (calculated by 0.7 CNY per kWh in electric charge for one year)
