Smart HelSys

-48VDC Rectifier System up to 3kW

Smart HelSys system is a compact and intelligent power system, it can house up to 3 rectifiers of 1kW and 1 SC501 controller. Integrated DC system capability with controller and distribution module options, allow customers to have a complete DC Power System in 1U height.

Smart HelSys system is designed for a wide range of telecommunication applications such as fibre optic network, satellite communication ground station. transmission equipment, mobile communications and 5G base station/micro base station.

Features

  • The rectifier uses the active Power Factor Compensation (PFC) technology, the power factor is up to 0.99.
  • The system has a wide AC input voltage range: 80Vac ~ 300Vac.
  • The rectifier uses soft switching technology, the efficiency is up to 95%.
  • The rectifier safety design complies with UL and CE standards.
  • The monitoring module has perfect battery management. The management functions include the LLVD, BLVD, temperature compensation, auto voltage regulation, current limitation, battery capacity calculation and on-line
  • battery test, etc.
  • The monitoring module can save up to 1000 pieces of historical alarm records.
  • The system has complete fault protection and fault alarm functions.
  • Front access and front connection. High convenient for installation and maintaining.
  • Smart HelSys System provides multiple communication ports (such as RS232, Ethernet and dry contacts), which enables flexible networking and remote monitoring.
