DC SCR drives

Many plants still run reliable DC motors on older lines. An SCR drive converts AC supply to adjustable DC voltage to control the motor's speed and torque. Send the drive's nameplate, or the motor's horsepower, armature voltage and field voltage, and we'll quote a direct replacement or a current equivalent.
