2 - Introduction to the product

AFE200 is the series of AC/DC Active Front End (AFE) regenerative power sup-
ply units
With a powerful 32-bit technology platform and reliable IGBT power stage the
AFE200 offers significant advantages for single or multi-inverter automation sys-
tems powered by a common DC bus.

Reduced operating costs
The AFE200 achieves considerable savings in terms of power consumption
and the relative costs. The kinetic energy of the inertia of the loads transformed
into electric energy by the AFE200 is sent back to the mains supply during
braking. In conventional resistor braking systems this power is dissipated in the
form of heat. The excess energy can be used to supply other equipment.
Production of Clean Power
The regeneration technology of the AFE200 uses advanced control algorithms to
provide clean power. A significant reduction in harmonic distortion (less than
5%) and the input current in phase with the input voltage enable unitary power
factor operation, for additional energy saving and system efficiency.
Enhanced control dynamics
Used in single or multi-inverter solutions powered by a common DC bus the
AFE200 also guarantees high-level control dynamics in drive and energy regen-
eration conditions, which would be impossible with electric braking solutions.
Control and monitoring performed on the DC-link also prevent the risk of undesir-
able stoppages during power transients and make the AFE200 a reliable solution
for use in networks with high voltage fluctuation levels.
Typical applications
The AFE200 is ideal for applications that require management of high-inertia loads
or with high operating dynamics, such as: test benches, industrial lifting applica-
tions, centrifuges, mixers, ventilation systems, renewable energy systems, rolling
systems, high-power servo systems, etc.
The economic benefits of using the AFE200 in applications such as these are not
of secondary importance.
