Introduction
Before using the EB500 Power Amplifier, carefully read this manual and other
documentation that came with your amplifier. This will allow you to reduce the risk of failure
of this product.
EB500 is a transistor linear VHF power amplifier designed for use with amateur radio
stations. Distinctive features of the EB500 amplifier:
– instant availability for operation;
– compact size, light weight;
– no need to replace components due to wear;
– increased service life;
– lack of high voltage in the high-frequency part;
– the ability to automate operation.
Operating Precautions EB500
For the power amplifier to work properly, you must follow some precautions:
– The operation of the amplifier without an appropriate electrical grounding
system is required;
– If possible, organize the chassis grounding of the radio-transmitting device, which
will ensure the most efficient and stable operation of all the equipment of the
amateur station, and will reduce the level of possible interference and RF
interference; ground all station equipment to a common ground.
– If the protection systems of the amplifier are repeatedly activated, it is necessary to
stop the operation of the amplifier until the causes of the emergency shutdown are
eliminated. Multiple tripping of protection systems can damage expensive LDMOS
transistors;
– Do not drop, or damage the case, or allow foreign objects inside - this may lead to
the failure of the electronic components of the E500 power amplifier.
– Do not operate the power amplifier with the covers removed to avoid overheating of
the device. The absence of covers disrupts the cooling system.
