1.0 DESCRIPTION
1.1 Overview DG2 PLUS series non-regenerative two quadrant thyristor controllers
are designed to control the speed of wound field or permanent magnet
dc motors from ¼ to 5 hp. These drives can also be modified to become
torque control regulators.
· Impedance-isolated armature voltage feedback
High impedance resistive voltage divider network used for armature
voltage feedback.
· Tachogenerator feedback
50 volt/1000 rpm tachometers may be used for speed feedback.
· Dual AC line voltage
120 or 240 vac line voltages are plug selectable.
· Dual field voltage
50/100 or 100/200 volt field supplies are link selectable.
· 10V reference supply
· LED indication
Run relay energized
Power "ON"
