Electronic Modules Ver. 0002 EM - 5
EM.1 POWER SUPPLY MODULE
They are directly connected to 380-460 Vac, 50/60 Hz Mains and provide a dc voltage output
of about 600 Vdc depending on Mains power. This voltage supplies to the Drive Modules
through what we call Power Bus.
These Power Supplies also handle the energy excess accumulated at the Power Bus usually
due to motor braking.
We call them Non-regenerative Power Supplies when this excess of energy is dissipated as
heat on certain electrical resistors.
We call them Regenerative Power supplies when this excess of energy is returned to Mains.
This option reduces the consumption of the electrical signal without generating additional heat.
Non-regenerative Power Supplies
They are the ones referred to as PS-25A, PS-25B and PS-65A, and provide 25 and 65
kilowatts to the Drives respectively. They admit a voltage range between 380 Vac to 460 Vac.
The previous PS-25 and PS-65 only admitted 380 Vac. See appendix D.
Regenerative Power supplies
They are the ones referred to as XPS-25 and XPS-65, (25 and 65 kilowatts) and they can
return 16 and 41 kilowatts respectively in a continuous fashion.
They admit a voltage range between 380 Vac and 460 Vac.
When energy regeneration is activated, the "REGEN" lamp turns on.
The module also has a little Ballast Circuit for dissipating energy in an emergency. That is,
when there is no Mains voltage and the overvoltage alarm goes off.
These modules also offer an Auxiliary 24 Vdc Power Supply for the control circuits of the Drive
modules.
