3. Telecom Rectifier Quick Details

  • Standard 19-inch width for versatile usage
  • 2U height compact design, saving space and installation costs
  • Front operation and cable access for convenient maintenance
  • Advanced battery management for prolonged battery life
  • Various communication ports for flexible networking and remote monitoring
  • Hot pluggable rectifier and controller for easy online maintenance
  • Wide input voltage range (85-300Vac) for adaptability to power grids

 

4. Working Principles

 

(1) AC input: Startup rectifier module after AC powered-on, outputs -48Vdc, at the same time charge the battery and power the conversion module, conversion module outputs 220Vac.

 

Under normal conditions, the parameters of rectifier module and distribution unit are all under controll of the monitoring module, operating according to the preset parameters or user’s commands. If AC mains fault,

the battery will power to the system, and continue outputing - 48 VDC and 220 vac, with the discharge of the battery, the voltage of the battery starts to descend, when the voltage is under 43.2 V + / - 0.5 V,

the monitoring module send battery under-voltage signal and close the load output directly, then the power system will stop working. When external AC mains recovers,

the system will normally work again. (All above monitoring data are system default values and can be reset by user)

 

(2) -48V input: No AC current or no AC be connected, access external power -48V to -48V load port, startup monitoring and conversion module, 220Vac output.

 

5. Rectifier module

There are three indicator on the panel,which are used to reflect the operation status of the rectifier,see Table below for details.

Table Rectifier indicator description

 

Indicator Color Status Reasons for abnormal status
Power indicator Green Normally on The module has and power input
Off Main supply fault(no power input or OVP,UVP of power input).non-output
Alarm indicator Yellow Normally on Temperature alarm(OTP when the ambient temperature>65℃)
The module is hibernating. (indicator lighting, no alarm)
The module is current-limiting
Flickering Communication failure
