When an old inverter driving airflow
through a simple wind tunnel broke
down, bringing student research to a
stop at Coventry University, Lenze
partner Modern Drives & Controls
stepped in with an IP65 enclosed
SMV inverter. Two working days later
the wind tunnel was back in service.

The Lenze SMV inverters can be
mounted without a panel in areas
where there might be splashed water
or low pressure jets. They cover a
range from 0.25 to 7.5kW with
options for 1 and 3 phase supplies in
a range from 120 to 600VAC. The
wind tunnel required a 0.75kW drive
for a single phase 240VAC supply.

SMV inverters are sensorless vector
drives with high performance, for
example 200% starting torque and a
highly dynamic response.
