POWER SUPPLIES
The FAGOR power supplies are connected after the filter to mains (see figure F.
H1/1) with a line voltage between 400 and 460 V AC at a line frequency of 50/60
Hz and its functions are:
 Provide a DC voltage output that will supply the modular drives through the
power DC BUS.
 Manage the energy excess accumulated in the power DC BUS as a result of
braking the motors
Hence, we refer to:
Non-regenerative power supplies
when they provide a DC voltage output
(depending on line voltage) and its exceeding energy is dissipated as heat in
electrical resistors.
Regenerative power supplies
when they provide a DC voltage (depending on line
voltage) and its exceeding energy is returned to mains, hence reducing the
electrical consumption without generating additional heat.
Regenerative regulated power supplies (boost power supplies) when they provide
a programmable DC voltage (depending on line voltage) and its exceeding energy
is returned to mains with a power factor close to 1, hence reducing the electrical
consumption without generating additional heat.
