    The PJ1000-LIGHT is an radio broadcasting amplifier manufactured by R.V.R. Elettronica SpA featuring adjustable RF power output up to 1000 W under 50 Ohm standard load and less than 20W drive power requirement. The PJ1000-LIGHT has been designed for installation in a 19”x3HE box for rack. The amplifier incorporates a low-pass filter to keep harmonics below the limits provided for by international standards (CCIR, FCC or ETSI).
  • Page 8 PJ1000-LIGHT The amplifier management software is based on a menu system. User has four navigation buttons available to browse submenus: ESC (chap. 6.1 - [6]), and ENTER (chap. 6.1 - [9]). The rear panel features the mains input connectors with a mains voltage switch (chap. 6.2 - [18]) to select the appropriate mains input voltage, RF input and output...

    PJ1000-LIGHT 5. Quick guide for installation and use This section provides a step-by-step description of the machine installation and configuration procedure. Follow these procedures closely upon first power-on and each time any change is made to general configuration, such as when a new transmission station is added or the exciter is replaced. Once the desired configuration has been set up, no more settings are required for normal operation; at each power-up (even after an accidental shutdown), the amplifier defaults to the parameters set during the initial configuration procedure.
  • Page 10 PJ1000-LIGHT 5.1.2 Mains power supply WARNING: Disconnect mains power supply before beginning these procedures. Both power supply units (please see chapter 8.1 for a detailed description) are equipped with fuses and voltage selection blocks: check all fuses and voltage selection blocks to ensure they are properly rated for the power mains and change them as required to match mains voltage.
