Electronic tube expanding controller type NFAB-S and NFAB-S/1
The electronic tube expanding controller is used for exact and repeatable power control of electric driving motors for tube expanding work. The controller is designed for connection of three phase A.C. motors of different types and power ranges. The electronic measurement and control of electric power secures the precise breaking torque and guaranties the repeatability of the expanding rate. A control system adapted to the expanding procedure assures optimal economy. The handling is very easy. The expanding cycle will be started by foot-pedal switch.
