Congratulations on your purchase of the 8101 AE Techron power supply amplifier, featuring an advanced 
switch-mode design that result in low noise and distortion and high power density. The 8101 amplifier is built 
and tested to the most stringent quality standards for long life and outstanding performance. The AE Techron 
brand is known throughout the world for its robust precision amplifiers as well as its product service and 
support. 

1.1

 

Features 

The 8101 amplifier is configured as a dual-channel, AC-coupled, controlled voltage amplifier ideal for 
reactive loads. It can be used for both pulse and continuous duty applications. Other features include: 

 

 

Up to 16 Arms and 139 Vrms continuous output. 

 

Frequency bandwidth at full power of 10 Hz - 20 kHz. 

 

Compact design; only 2U of rack space and 27 lbs. 

 

Switching, power supply for reduced weight. 

 

Installs easily into a standard 19-inch rack or stands alone for bench top operation. 

 

Built-in protection circuitry safely provides for sustained high-power output, with 
protection against input overloads, improper output connection (including shorts and 
improper loads), and excessive temperature, voltage or current.  

 

Operates from single-phase, 120-volt AC mains, (230 VAC version available).
