PJ1000M-C
4. General Description
RVR Elettronica’s PJ1000M-C is an extremely compact (just 3 U) 19” rack-mountable
broadband MOSFET RF power amplifier for FM audio broadcasting.
It works without adjustment in the whole 87.5-108MHZ FM band, its overall efficiency
is about 70 %, so that its power consumption is just about 1450 W at its nominal
1000 W RF output.
The RF power section is based on four SD2932 MOSFET, able to deliver 300 W
maximum each.
The power supply is a switching mode with a maximum power output of 2 kW. It
includes PFC (Power Factor Correction) and its efficiency is more than 90 % with a
power factor better than 95 %.
The PJ1000M is controlled by a microprocessor system including a LCD display,
implementing the following functions:
•
Measurement and display of the amplifier's working parameters
•
activation and deactivation of the RF power output
•
protection of the amplifier against dangerous sistuations like exceeding output
power or SWR, overdrive or overtemperature
•
Uper-fast protection agains excesses of reflected power, temperature, current,
voltage and driving power
•
Interaction with external devices using the telemetry connector.
The amplifier’s management software is menu-based.
The user can navigate through the different menus and change the relevant parameters
rotating the encoder left or right. The encoder will be pressed to enter into a submenu
or to confirm and store into non volatile memory a parameter’s new value.
The status of the machine is summarized by a row of LEDs on the front panel. The
LEDs are red, yellow or green if they indicate respectively a fault, warning or correct
working condition.
With the knob, it is possible to select LOCAL or REMOTE mode; the LOCAL status
is also signalled by a LED on the front panel. LOCAL mode permits to control the
machine using the buttons on the front panel, while remote control (that is using the
telemetry connector) is disabled. In REMOTE mode, the menu system can be used
only to read the parameters, but commands can only be given by the remote connector.
Different working parameters are made available for the user on the telemetry
connector, as voltage levels that are proportional to the value of the parameter under
consideration.
A built-in low-pass filter keeps the harmonic emission level below CCIR and FCC
permitted levels.

5. Installation and Use
5.1
Preparation
Unpack the amplifier and before any other operation check the absence of any
damage due to the transportation. In particular, verify wether all the controls and
connectors on the front and rear panel are in good conditions.
The amplifier is designed to work on a mains supply of 230Vac ±10%. Mains
variations up to 15% are tolerated. Higher voltages (approx 265 V) will force the
intervention of the protection system (“Mains” LED) and the immediate tripping of
the machine.
If the mains supply falls below 190 V, the management system will reduce the power
output to 500 W maximum. If the setting output power was under this value, no
reduction will happen.
For mains supply below 165 V, the immediate tripping of the machine will happen,
as for voltage above 265 V. The amplifier will perform automatic restart as soon as
the problem in the mains supply will be removed.
The PJ1000M-C includes a mains switch on the rear panel, completely breaking the
mains supply. Verify that it is in the “Off” position.
Connect to the RF Input the RF Output of a suitable exciter (for example the RVR
Elettronica’s PTX30) using a N-connectors terminated cable; the exciter shall be set
for minimum power and OFF.
Link the “INTERLOCK OUT” connector of the amplifier to the interlock connector of
the exciter, if available (it is in RVR Elettronica’s exciters).
Connect the RF output to the antenna cable or to a suitable dummy load.
The apparatus is designed to work with a 50 Ohm nominal load, with low reflected
power (suggested VSWR < 1.2:1). This kind of load will ensure better efficiency,
lower working temperature, longer lasting life of the apparatus and less power
consumption.
The antenna or dummy load feeder shall be correctly connected to the output coaxial
connector of the amplifier. We suggest to do this operation “by hand”, i.e. not using
wrenches or other tools.
Using cavity filters: The device can work with high Q - narrow band cavity filters.
The stability of the device is not guaranteed for all adaptation conditions and phase
angles. When the cavity filter is well-tuned, it will offer a purely resistive impedance
load only at its tuning frequency. Out of this band, the cavity is a reactive load with any
phase angle at the different frequencies, and the reflection is practically infinite. The
amplifier, on its side, is very wide-band (tens of MHz at - 3 dB), so that its load is “not
correct” apart from the narrow tuning zone of the cavity filter. Furthermore, to obtain
its high efficiency (class C..F) the output impedance of the amplifier is a function of
the input power.

User Manual
PJ1000M-C
It is extremely important to keep the PJ1000M-C in correct driving condition,
so that the output impedance will be controlled by its microprocessor system.
Connect a proper cable to the amplifier’s mains input. A mains plug is delivered with
the amplifier.
WARNING: It is essential that the unit is properly earthed to ensure both the safety of
operaton as well as the correct working of the equipment.
5.2
Use
Switch ON the amplifier and verify the green “PWS OK” LED being it. The LCD will
show a screenful indicating the forward and reflected power.
Contrary to many analogous devices, the PJ1000M-C includes a featureful
management and control system for the driving (input) power, independent from the
kind and make of the exciter.
At start-up, the exciter is connected with an internal relay to a 50 Ohm / 50 W dummy
load. Only if the input power level is inside the permitted window the start-up cicle will
be triggered and the power output will be enabled. The driving condition is indicated
by three LEDs on the front panel (yellow = not enough input power, green = input
power OK, blinking red = too much input power, red = input power excess with
disconnection of the driver and protection intervention). It’s important to alway operate
with correct driving power, that is around 18 W.
Switch the exciter on (to minimum power level) and wait for it to lock on the working
frequency. When the locked condition is reached, progressively increase its output
power, while checking the LEDs on the front panel of the amplifier. At low input power,
the yellow “AGC LOW” LED is on and the green “AGC OK” LED is off. Keep increasing
the exciter output: the two LEDs will start blinking alternatively. In this status, the
amplifier starts emitting RF power, and on the machine’s display the FWD power
increases up to the value stored in the filed “PWRSET”.
Increase the exciter’s output power until the LED “AGC LOW” goes off and “AGC
OK” is lit. This is the optimum driving condition.
The PJ1000M-C is normally delivered with the output power set low (approx 50 W).
The power setting can be performed directly or indirectly, depending on the exciter
being connected ad active or not.
The default screenful reports two power indications: on the upper line, PWRSET
indicates the setting value, while on the bottom line the current output power (both
forward and reflected) is given. Pushing the knob, the indication “PWRSET” starts
blinking, and rotating the encoder the setting value will be modified as needed. If the
exciter is on and the amplifier’s output power is enabled, the actual emitted power
will follow in real-time the setting value. Pushing again the knob the new value will be
stored. If the exciter is off, as soon as it will be switched on the output power will
reach the setting value with a ramp (soft-start).

PJ1000M-C
Adjusting the output power of the amplifier acting on the output power of the
exciter is not possible: when the input power goes below the minimum
threshold the amplifier’s power output is disabled. This kind of regulation
would in fact change the amplifier’s class, with bad consequences on gain,
efficiency and stability.
At this point, it is possible for the user to verify all the working parameters of the
amplifier using the management software.
Normally, the device doesn’t require any human supervision for its normal operation.
If any alarm condition arise, these are automatically managed by the embedded
protection system, and notified to the user with the LEDs on the panel or via
messages on the LCD display. When an alarm condition arises, a temporary
deactivation of the output power is performed. If the alarm condition is still there at
the reactivation of the power output, a new deactivation/reactivation cycle will be
performed. After 9 such cycles, the amplifier is definitively switched off, and the red
LED "fault" on the front panel is lit. The cause of the fault is stored in memory. The
alarms counters are reset if no alarm arises for 45’.
For example, reflected power above 100 W causes an immediate intervention of
the protection system. The machine will be deactivated and reactivated up to 9 times.
After this cycles number, the amplifier will be definitely blocked (LED “Fault” lit) with
the indication of the cause of the fault (LED “P. REF” lit). A manual reset by the operator,
local or remote, is required for the machine to restart.
NOTE: If the amplifier is in “remote” mode, no local modification is possible.
Remote mode is prioritaire. Before resetting the alarms, it’s necessary to pass
in “local” mode!
5.3
Encoder
The PJ1000M-C’s control system is based on a LCD and a knob (“encoder”). With
this system the user can check and modify all the configurations, like powerlevel,
power output activation, local or remote mode.
The interaction between the user and the exciter’s control software is performed
using the encoder.
The operations supported by the encoder are:
10 / 24
•
rotating: scrolls the submenus, modifies the parameters
•
pushing: selects the parameter to be modified, stores the value and accepts a
selection

Alarms menu
This menu gives to the user all the information related to the embedded protection
system of the amplifier..
It comprises a number of sub-menus, each containing the name of the variable
checked by the protection system and the number of the protection interventions,
due to this variable, performed by the system.
Chapter 6.1.7 describes all the monitored variables.
To access the submenus, first push the encoder. Than, rotating the knob will display
the pages related to the different variables.
The firs line describes the kind of alarm, the second indicates the number of the
related protection interventions. When the number of the protection interventions of a
single variable reaches the configured maximum of 9, the amplifier goes in permanent
protection mode: the power supply and thus the power output is disabled and the
LED “Fault” on the front panel is lit. The display will show the following screenful:
To let the machine restart, remove the cause of the misfunctioning (for example the
antenna feeder is badly connected) and push the encoder.
The last of the submenus of the alarm menu is used to get back to the main menu:
