  • High safety, no accessible bare live conductor is present when the door is closed or opened; Insulation failure or grounding fault alarm functions are supported for DC buses and DC output branches; Separate distribution monitoring is supported for DC distribution units with 7-inch touch screens to display the running status and provide automatic fault alarms.
  • High power factor, high-efficiency and low THD.
  • Strong ability in adapting power grids. Normal operation within the input voltage range of 260 ~ 530 VAC and can withstand 600 VAC input with automatic protection against phase failures.
  • Digital active load sharing. Stable load sharing function with imbalance <±5%, rectifier can operate stably with active load sharing function when the controller is disconnected.
  • Web-based monitoring. Real time remote monitoring via Ethernet, Modem or RS232 port
  • Safe and reliable. Comprehensive lightning protection at AC side, DC side and signal interfaces
  • Damage-free hot plugging/unplugging supported for rectifier and controller modules; easy and fast online maintenance.
  • Startup with diesel generator input. With resistance to transient over voltage of diesel generator, the system does not require strong diesel generator outputs.
  • Specialized parallel design for capacity expansion. Easy online parallel connection or upgrading cut-in.
  • Higher power density and small footprint.
  • Green design. Rectifier standby supported to improve system efficiency; advanced EMC design for Class A conduction and radiated emissions​
