VACON® NXS – the reliable choice
VACON® NXS is a compact AC drive in the power range of 0.37 – 560 kW and
supply voltages of 208 – 690 V for heavy use in machines, buildings and all
branches of industry.
The robust design incorporates effective
protection against supply network
disturbances. Trip-free operation is also
guaranteed due to sophisticated motor
control principles and motor/drive
protection features, component
selection and effective cooling.
Enclosure classes of IP21 and IP54 and
integrated high-level EMC filters make
the VACON® NXS suitable for all
environments.
The Start-Up Wizard and the standard
All-In-One application package make
parameter setting extremely easy in all
cases, from simple to complex.
The wide and flexible standard I/O and
option for five I/O boards provide
versatile controllability. The most
common fieldbus options are also
available.
The modular design of the VACON® NXS
brings several advantages: the control
terminals are safely separated from
power terminals, upgrading the control
inputs and outputs is easy and
convenient, replacing the cooling fan
(the only regularly replaceable
component) is fast, the display panel can
be utilized for parameter copying, etc
.
The mechanical design is extremely
compact. The IP54 units in particular
are the smallest AC drives on the
market. All units are suitable for both
wall and enclosure mounting with all
necessary components: integrated EMC
filters, AC chokes, cable protection, dust
and water protection. The effective
super-cooling principle allows high
ambient temperatures and high
switching frequencies without derating.

Easy to use display panel
Interactive programming
with Start-Up Wizard
Versatile All-in-One package
