AC Remote Amplifier Control Unit


Michigan Scientific Corporation :PS-AC Remote Amplifier Control Unit 

 

 

 

Description :
 

Michigan Scientific's AC Remote Amplifier Control Unit is a complete system for controlling all Michigan Scientific spinning amplifiers. The PS-AC powers the amplifiers, controls excitation to strain gage bridges, and commands spinning strain gage amplifiers to apply their internal shunt calibration resistor to the appropriate arm of the strain gage bridge. The bridge excitation off feature allows the user to detect self-generated system response (noise) from undesired environmental conditions.
*5 Volt bridge excitation @ 350 ohm
 
-Controls up to 18 spinning strain gage amplifiers*
-Remote bridge excitation On/Off capability
-Remote electronic shunt calibration capability
-Bipolar power supply for spinning amplifiers
-Ideal for laboratory applications

ENVIRONMENT

 

Operation

0 to +50°C (+32°F to +122°F)

Storage

-40°C to +85°C (-40°F to +185°F)

 

Controls :
 

Power (On/Off): Activates the remote amplifier control unit and illuminates LED.
Bridge Excitation (On/Off): When used with a modular strain gage spinning amplifier, this turns the excitation to the bridge on or off without turning off the amplifier. This is done by inverting the polarity of the ± 15V supply pins.
