PDU0003F3V3

PDU0003F3V3

6-WAY POWER DISTRIBUTION UNIT

The PDU0003F3V3 product has been designed to operate in conjunction with Kaelus TMA0004. The PDU distributes power for up to six Tower Mounted Amplifiers and provides alarm indications through LED and output relay connections.

FEATURES

  • 22V through 60 V DC input range
  • Up to six +12V DC LNA output ports
  • LED status indicators for each individual TMA
  • TMA summary relay alarm output
  • 19 inch rack mounting

alarm operation
Upon a manual reset of the front panel switch the PDU measures the current flow in each of the DC outputs and if the current falls between an upper and lower limit of a valid operational current range then the TMA is permanently powered. However, an output will be disabled if an open circuit (no TMA connected) or short circuit (installation fault) is detected. Once a TMA is operational, a significant change in operating current is detected by the PDU and causes alarm states to be raised according to the table below. Current operating windows are factory calibrated to suit the TMA with which the PDU is intended to work.
TMA current (mA) Status LNA Indicator LED
>350mA (upper limit) LNA faulty voltage removed Red constant
250 - 350mA LNA OK and operational Green constant
< 250mA (lower limit) LNA faulty voltage removed Red constant
