Product Description
The VariFlex is a simple and
compact AC variable speed
drive for use with 3-phase AC
induction motors. The drive's
first 10 parameters which are
shown on the front cover are
all that are required for 90% of
all applications. The VariFlex
employs state of the art micro-
processor technology which
controls all drive functions. A
Digital Signal Processor syn-
thesises an adjustable carrier
frequency Pulse Width
Modulated output controlling
the Insulated Gate Bipolar
Transistor (IGBT) inverter sec-
tion. Another microcontroller
handles the user interface
functions. All printed circuit
boards are manufactured
using surface mount technolo-
gy ensuring high quality and
reliability.
