Leeson Speedmaster SCR Controls are for general purpose permanent magnet or shunt wound DC motors. Regenerative drives operate in two additional quadrants: Quadrant 2 and Quadrant 4. In these quadrants, motor torque is in the opposite direction of motor rotation. Regenerative drives can reverse a motor without contactors, switches, brake resistors, and inhibit plugs. They can also control an overhauling load and decelerate a load faster than it would take to coast to a lower speed.More features include:
- Four quadrant - Full wave - Open Chassis with Speed Pot
- 1/4-1HP @ 115 Volt / 1/2-2HP @ 230 Volt Input and 90 volt or 180 volt DC output
- Requires an additional heat sink, p/n 175722, when the continuous armature current is above 7 ADC
- Adjustable minimum and maximum speed for customization
- Adjustable IR compensation
Leeson Electric is part of the Regal Beloit family, and is an established brand.
