PSU
The PSU is located in the bottom middle of the cabinet or in an equipped high cover. The
PSU has all the voltages required for the WRH. It has capacity for the radio circuitry, fiber
optics, modem, etc., and also supplies the BA if used. Multi-band WRH-Vs always require a
second PSU. There are two PSU types with different input voltages:
1. 115/230V 50/60Hz, 300W input max.
2. 21- 60V DC, 300W input max.
The DIA provides most of the internal connection between the sub units and external ports.
Connectors involved in the installation are also located on the DIA. Table 2-13 describes
these connections.
