INTRODUCTION
K-DUCER NT is the new class A low torque intelligent transducerized assembly system
from Kolver.
Thanks to a sophisticated control system, the electronic circuit communicates with KDS-NT
(Patent pending) series screwdriver equipped with integrated torque/angle transducer and
allows to stop the screwdriver instantly when reaching the preset torque or angle.
The AC 90÷260V - 50÷60Hz power supply is converted into 30VDC required by the
screwdriver through a switching board.
IMPORTANT: K-DUCER NT is a highly accurate unit, but it is critically important to select
the appropriate settings to ensure that the desired and proper torque is being applied and
that the screwdriver motor works efficiently. Read the manual carefully and if unsure
please contact Kolver for support.
