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.

• Power output enable/disable.

• User-selectable threshold settings for output power alarm (Power GoodUser-selectable threshold settings for output power alarm (Power Good feature)

• Measurement and display of amplifier operating parameters.

• Communication with external devices such as programming or telemetry

systems via RS232 serial interface or I2C.

Four LEDs on the front panel provide the following status indications: ON, LOCAL, FOLDBACK and RF MUTE. On left side, four LEDs provide indications relatively the status of RF signal amplified: FAULT, FUSE BLOWN, FOLDBACK and ON. At last, on right side, four LEDs provide indications relatively the fault status of power supplies: PS1, PS2, PS3 and PS SERVICE.

5.1 Installation

5.1.1 Preliminary Requirements

The equiment ventilation and the work space must be suitable for maintenance operations according to the directive in force in the country in which this device is installed.

It is necessary to leave a minimum distance of 50 cm on the front and back sides of the device to have a proper functioning and to facilitate air circulation through the ventilation grids.

In any case, the device must respect the distance established by the safety directive in force in the country where this equipment is installed.

This device is designed to operate at -10 °C to 45 °C without loss of performance. The ambient air must be clean of dust and not condensed; the maximum humidity must never exceed 95%.

It is important to remember that strong changes in temperature can lead to generation of condensation, in particular environmental conditions. In case of the station where this device is located should be subjected to these physical events, it is good to monitor these devices, once you put it into service, in addition to trying to protect the device itself as much as possible.

IMPORTANT: never supply voltage to the equipment in presence of condensation.

This problem can occur more frequently in devices warehoused for a long time or in those used as an active reserve.

The antenna RF, power supply and connection cables must have the section suitable for the maximum current intensity.

5.1.2 Preliminary checks

Unpack the transmitter and immediately inspect it for transport damage. Check carefully that all the connectors are in perfect condition and check for the absence of humidithy. Otherwise, wait until it is completely dry.
