4.2 Features

The overall efficiency of PJ6000U-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 between +0.25 dB and -3 dB (+5% and -50%) referred to the nominal power of the equipment: for example from 3000W to 6300W in case of PJ6000U-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 PJ6000U-K requires 50 W) and then successively adjust the bar setting of power on amplifier in order to obtain the desired output power.

User Manual

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 PJ6000U-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.

PJ6000U-K

The RF power section of PJ6000U-K uses eight LD-MOSFET (MRFE6VP61K25H) modules delivering up to 750W output power each.

An LCD on the front panel and a push-button panel provide for user interfacing with the microprocessor control system, which implements the following features::

• Output power setup.

5.1.3 Device power supply connections

PJ6000U-K

Provide for the following (applicable to operating tests and putting into service): √ Single phase mains power supply (P+N) 230 VAC (-15% / +10%) or three phase

mains power supply (3P+N) 400 VAC (-15% / +10%) , both with adequate earth connection.

√ FM exciter with adjustable output power up to 50W (minimum), as the RVR

Elettronica PTX60LCD/S.

√ For operating tests only: dummy load with 50 Ohm impedance and adequate

capacity (6000W as a minimum).

Nota: to ensure the safety of the operators, carry out the wiring according to the

laws and regulations in force in the country where this equipment is installed.

Check that the POWER switch on the front of PJ6000U-K is in the “OFF” position..

An ILME model KKCNTCQF04/2 (CQF04/2) multipole socket is supplied with the amplifier to power the machine. The socket must be connected to the multipole cable that will be wired to the mains switchboard.

WARNING: to avoid any risk of shock make absolutely sure that the power

supply cable is NOT powered when the multipole socket is connected to the cable itself..

5.4 Protection SystemProtection System

The protection system implemented inside the amplifier is based on two types of intervention.

The first reaction is called “Foldback” and consists in decreasing the voltage in the power amplifier when the forward or reflected power exceeds the proportional limit voltage value. As such, the amplifier’s gain is reduced and the overall result is an action that opposes the increase of the forward or reflected power. The yellow LED on the front panel indicates the tripping of the foldback circuit..

The second type of reaction consists in turning OFF the equipment’s amplifying section when a specific variable exceeds a set value..

Depending on the type of event that has occurred, after that the amplifier has been turned off, it will be reactivated after a fixed time interval or only after that the sharing which caused the block has been removed..

26 / 48

When the protection system trips due to a “cyclic” type parameter, a counter begins counting up (the X value in the alarm menu). If the counter reaches the max admissible cycle value (Y), the amplifier turns OFF definitely and the red “FAULT” LED lights up on the front panel..

User Manual

27 / 48

Rev. 1.0 - 21/03/18

The user may press the ALARMS RESET key, in alarms menu, to interact with the protection system. ..

If the system is transmitting but alarms were triggered earlier causing certain counters not to be at “0”, will have no effect unless it is pressed while inside the alarm menu. As such, the system will be sure that the user takes note of the alarms that were triggered before resetting them..

The system resets the alarm counters automatically after thirty minutes of operation, i.e. the user need not do anything, if the amplifier does not trigger any alarms or after the machine the machine has been turned OFF and then back ON..

5.4.1 Auxiliary Protection

The amplifier contains a second microcontroller that manages local measurements and carries out auxiliary protection functions of the machine together with the main protection system. This microcontroller card indicates its interventions via LEDsii interventi tramite i LED.

PJ6000U-K

A delivered power automatic back-off mechanism is envisaged for excess temperature, SWR or current absorbed by a MOSFET module. The yellow FOLDBACK LED indicates this case..

A FAULT signal is triggered (red LED) when a fault occurs that stops the power amplifier. This situation is signaled to the machine’s main microcontroller as well and triggers a lock situation (FAULT)..

The LED FUSE BLOWN indicates that one of the fuses that protects the power supply of the MOSFET modules has blown. In this case the machine keeps running as usual (obviously without the contribution of the module) even if it is advisable to single out and clear the cause for the malfunction and replace the fuse as soon as possible to fully restore the machine’s working efficiency..

5.4.2 Power Supply UnitsPower Supply Units

Three power supply units, which work in parallel mode, power the machine. Should one of the power supply units malfunction, the machine automatically compensates the delivered power down to a value compatible with the current deliverable from the surviving power supply. This situation is indicated by the “PS” LEDs on the front panel..
