Information
The Model
700A Pouer
Amplifier is completely solid state and
contains no mechanical circuit breakers or relays.
Even its
aver-tamperature sensor is a solid state device.
Designed for
severe industrial applications, the Model
700A Amplifier is
protected from damage uhich might be caused by excessive l/SUR,
high instantaneous line current, excessive output pouer or
over-temperature operation.
A built-in time delay and zero-
crossing turn-on reduce current inrush to prolong component
life.
Pouer Supply voltage regulation is used to remove noise and
output
fluctuations.
A directional uattmeter and front panel selector
switch provide convenient measurement of the forward pouer from
the amplifier and reverse pouer reflected by the load.
A
non-linear meter scale allows extremely sensitive tuning of the
load simply by adjusting for minimum reflected pouer.
The Model
700A c o o l i n g 'is provided by self-contained
fans.
Air
is drawn in through filtered inlets to protect the circuitry
from
exposure to excessively dirty environments uhich may be
encountered
in industrial applications.
All sub-assemblies are plug-in and
can be readily removed for maintenance and repair.
The Model
700A may be purchased initially for lou power
requirements
and when additional power is required another Model
700A and a
hybrid power combiner may be used to provide performance
equivalent
to our Model 140ÖA.
The Model
700A is complete with a built-in 115 VAC pouer supply,
regulators, pouer meter and protection circuitry.
It is normally
supplied in a handsome bench top cabinet uith rack mounting
available as an option.
