4.2 Features
The overall efficiency of
PJ5000U-K
is better than 70% across the bandwidth, for
this reason are part of
RVR Green Line
family.
This performance characteristic is guaranteed in a range b0.25 dB and -3
dB (+5% and -50%) referred to the nominal power of the equipment: for example
from 2500W to 5250W in case of
PJ5000U-K
; outside these limits the equipment
is able to work properly but can not guarantee an efficiency of 70%.
The operating logic during the output power regulation, which is necessary in
order to not deteriorate the efficiency even of 5-6%, expects to set the pilot power
to the optimum power (dependent on the amplifier: for example the
PJ5000U-K
requires 50 W) and then successively adjust the bar setting of power on amplifier
in order to obtain the desired output power.
The amplifier incorporates a low-pass filter to keep harmonics below the limits
provided for by international standards (CCIR, FCC or ETSI).
Two major features of
PJ5000U-K
are compact design and user-friendliness.
Another key feature is its modular-concept design: the different functions are
performed by modules with most connections achieved through male and female
connectors or through flat cables terminated by connectors. This design facilitates
maintenance and module replacement.
