HMC Electronics PLUTO10D Kolver PLUTO DC Controlled Electric Torque Screwdriver - Manual (Page 5)

3. Power supply and torque control unit
EDU1AE power supply and control units act as voltage transformer and electronic
torque controller.
The power supply 230V-50Hz AC is converted into 40V DC required by PLUTO
series screwdrivers through a transformer certified EN61558-1/p2-6.
The electronic control circuit cuts the power supply to the motor calculating the
correct torque in response to 3 parameters, voltage frequency and current,
according to the selected options.

All units are equipped with a power outlet on the back panel with autostopping fuse
holder certified IEC/CEE22. To replace the fuse just pull out the fuse holder and
change the fuse.
Always remember to switch off the control unit at the end of each working shift.
WARNING: always disconnect the mains plug of the power supply before
operating on the control units.
4. Adjusting the torque
The torque delivered by PLUTO screwdrivers is controlled through an advanced
electronic circuit with no need of any mechanical clutch device.
You can select the desired torque as a percentage of the torque range of the
selected screwdriver (see the manual of the control unit to check all the details).
When the pre-set torque is reached the screwdriver stops immediately providing
accurate joint tightening with consistent repeatability and high Cp and Cpk values.
