This unit is having arrangement for distributing the common 48Vdc supply from Power plant to four separate BTS systems. Apart from distribution, it also incorporated with fuse protection and four channel DC Energy meter.

The DC Distribution panel is inserted in series with 48V Battery and BTS equipments. It gives 4 output rails of –48V each going to the corresponding load/BTS. The unit measures the voltage and current drawn by each BTS sub system. 7 segment LED displays the parameter voltage, current, power and energy.

The unit computes the individual power and accumulates the energy consumption of each channel separately. The energy units consumed by each channel are stored in non volatile memory. Even if the unit power is removed this energy unit’s memory will not be lost.

   

Technical Specification :

  • Max. input voltage : 65Vdc
  • Max. output current each channel : 75 Amps DC
  • The energy consumed by each channel is stored in non volatile memory.
  • It displays the energy consumed since last reset for each channel. It also displays the current drawn by each channel in Amps.
  • Total 6 digit 7-segment LED display.
  • Two keys, one for channel selection, one for parameter selection.
  • Accuracy :< 1%
  • Mounting: wall mount , Indoor
