FXM5
Control Techniques Controller Field Current 10-20Amp 480V DC

The Control Techniques FXM5 field regulator is designed to ocntrol the field current of DC motors up to 20 amps. When used with a Mentor II DC drive, the field regulator is controlled directly via the drive parameters. This allows full customization of the field control for any application. The FXM5 can also be sued as a stand alone unit when retrofitting existing appplications. 

The FXM5 is a single pase, controlled thyristor rectifier bridge with a control logic PC board. The bridge can be configured by jumpers to operate in single quadrant or two quadrant control mode.

The FXM5 may be independently controlled by an external reference or set for atuomatic field weaking (constant horsepower) or constand field current. Field economy control via contact or logic input and a field loss relay for protection are provided for stand alone operation. The FXM5 also ahd a bar graph display (10% increments of the selected range) for field current magnitude.
