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.
