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 EDU1FR control units for FAB and RAF series screwdrivers feature maintenance free state-of-the-art electronics, with no wearing components with a circuit design suitable to both lever start and push start with protection against current overload up to 10A. This design results in very low current to the driver's start switch and clutch switch to extend their life indefinitely.

Additional features:

• Suitable to universal supply from 90 to 260 V ac 50/60 Hz.
• Slow start (0-2 seconds) and RPM (60% to 100%).
• Visual indicators (green-red) for power on/off and clutch action.
• Reduced weight (1.3 lbs.) and compact size for easy placement.
• M12 waterproof connector with silver and gold contacts for perfect conductivity.
