CHAPTER 1
VJ12000-TR GENERAL DESCRIPTION
1.1
MECHANICAL DESCRIPTION
The VJ12000-TR is allocated in a 19" rack, 40H, 7 of which are free and can be used to
insert an exciter, a receiver or any other equipment. Two analog instruments are placed on
the hinged frontal panel (
) with all other controls and commands.
The rear panel (
) hasn’t any connectors but only the air input for the cooling blower,
completed with the air filter and the hole for power supply and external exciters cables.
A chimney is placed on top section of the rack (
) that allows to push out hot air. The
antenna connector is placed on the top part too. The type of connector for the ouput is 1"+
5/8 or 3” 1/8 (optional).
1.2
ELECTRICAL DESCRIPTION
The VJ12000-TR is a tube amplifier, with grounded grid configuration, working on the
frequency range 87.5-108 MHz.
This amplifier is able to operate at 12KW output power with a driving power of about 500
W. The amplifier has motorized plate, load and input tuning, and is able to cover the
completely frequency range. The VJ12000-TR is been projected to use a three-phases mains
voltage (monphase only on request).
