Communication Charger with
Parallel Operation MODULE

This  product is a DC power supply suitable for  charging telecommunication devices and batteries. It  is manufactured in 19″ Rack-mount type. The charging rectification system consists of SNMP, rectification module, SID, and DC distribution unit.

The system is stable and reliable. The battery life is extended due to precise charging characteristics and small ripples during  charging, floating/equivalent charging is automatically selected, and LCD instructions and remote management (SNMP) are available.

Features

  • Integral structure of rectifier and inverter

  • It provides both AC and DC power within the single system stably
  • Costs are saved since only one battery-block is used
  • All-in-one rack structure – footprint is minimized

  • It is manufactured in a hot plug-in mode, so it allows enabling module replacement and expansion without interruption during system operation

  • Customizable design and fabrication for AC and DC power capacities

  • Stabilize output voltage by employing SID (DROPPER)

  • RIPPLE (alternating current content) is very small and has a fast response speed with little variation in output voltage and very stable
