MOSFET as active components in the FM amplifying modules. This chapter briefly describes the machine's main features. Composition The PJ5KPS amplifier is made up of modules inserted in a 19" rack. The main modules are as follows: • 1 Control unit 5 1.2 kW RF amplifier modules...
• The RF amplifier section The power supply section of the PJ5KPS amplifier is made up of one or two three- phase transformers, each one associated with a rectifier circuit for generating the non-stabilized voltage of 80V that supplies the RF modules. The transformers and the rectifier circuits are mounted on removable carriages together with power inductors that help achieve a power factor of about 94%.
Page 15
PJ5KPS Figure 4-1 Block diagram of the PJ5KPS The RF signals generated by two exciters (in the redundant configuration) are first attenuated by 6 dB to improve the uncoupling among the stages and then connected to a coaxial relay commanded by the control unit. One of the two signals is closed on a dummy load built into the machine whereas the other signal is connected to the input splitter.
Page 16
The overall power that the PJ5KPS must supply is controlled by the microprocessor- based card of the splitter-combiner section according to the settings made on the control unit for the NOMINAL POWER and LOWER POWER parameters.
PJ5KPS 5. Installation and use This chapter contains the basic instructions for installing and using the PJ5KPS amplifier. If necessary, more in-depth information about the operating principles may be traced in the next chapters. Assembly For practical reasons and for transport safety, the machine is usually supplied disas- sembled to the customer.

PJ5KPS The modules have a groove at the top and one at the bottom: insert the modules so that the guides in the compartment fit into these grooves. Slide the module until the two fixing screws fit into their seats. Then tighten the fixing screws at the same time so that the module inserts into its compartment remaining parallel until it is perfectly in place.

PJ5KPS 7.6 Combiner and divider 7.6.1 Control Unit The RF combiner section too is equipped with it own microprocessor control unit. This is very important for the functionning of the whole transmitter because it checks the foldback line of the several RF modules. The value of the output power is managed directly by this micro controller.
PJ5KPS. 8.1 Microcontrol board Trimmers In the PJ5KPS are present microcontrol boards, one for each 1.2 kW module, one for the control of the power supply and one for the control of the combiner. The boards are identical, but in each the trimmers have diverged meaning.
PJ5KPS 8.2 Phase Adhutment of RF modules Each PJ5KPS RF module have a dip-switch (accessible on the frontal panel) for the regulation of the phase of the RF signal generated. The phase of each RF module could be modified independently to steps of 1.6° from- 12.8° to +11,2° (Figure 8.2).

Figura 8-7 Addresses regulation of RF modules 8.6 Services supply The services of PJ5KPS are supplied at 220V through a dedicated transformer. Between the services, are included the microcontroller cards of RF modules, those of the combiner and power supply and the control unit.
In the case the control unit presents a damage, it is possible assure the correct operation replacing, temporarily, the control panel with the card furnished together with the PJ5KPS. To effect the substitution, execute the following instructions: 1) Switch-OFF the amplifier. Remove the screw on the left side of the LCD panel, open the panel and individualize the necessary connectors to the operation of the emergency card.
Page 65
PJ5KPS 2) Disconnect all the cables connected to the unit control. 3) Unscrew the crews that fix the board to the rack and remove the panel from his place. 4) Connect the three connectors precedentely identified to the entries of the board, like represented in the photo.
Page 66
PJ5KPS 5) Fix the board to the rack, in the same position in which previously had fixed the central panel of control. Do attention to fix the side of the card from which the interrupter sticks out toward the outside of the amplier.

PJ5KPS avoid the accidental operating; throw the interrupter toward the outside, go on the desired position and release the interrupter. Now the emergency board is operative. When be used the emergency board, the amplifier acts with the parameters previously adjusted (for example: the level of power). To modify the parameters is necessary use the unit control.
