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.
