All Kolver screwdrivers work in combination with a control unit acting as an AC to DC transformer and torque controller. The electronic control circuit cuts the power supply to the motor as soon as the pre-set torque has been reached. The EDU1BL control unit for KBL Brushless series screwdrivers feature maintenance free state-of-the-art electronics, with no wearing components. They come standard with the torque knob to adjust the torque (from 60% to 100%) of current control tools and a green LED which indicates when the control unit is on.

KBL-FR screwdrivers work in combination with our standard EDU1FR controllers. This option allows existing customers to replace FAB & RAF drivers with no need to repace controllers.
