■ Variable speed drives for
all requirements
SED2 variable speed drives are avail-
able in different designs and sizes. The
power range of the IP20 devices ranges
from 0.37 kW to 90 kW. The IP54 designs
range from 1.10 kW to 90 kW.
■ Standard features
– Modular design offers maximum
flexibility in terms of configuration
– Very low motor noise level thanks
to high pulse frequency
– Complete protection of drive and motor
– Separate mains and motor terminals for
optimum electromagnetic compatibility
– Low Harmonic Technology (LHT):
Special technology for suppressing
harmonics without additional com-
ponents
– Plug-in type operator panels
– Control terminal strip without screws,
with removable I/O board
– Advanced IGBT technology
– Microprocessor control
– Quadratic U/f characteristic
– Flying restart
– Automatic restart on power failure
or operating fault
– Self-regulating PID controller
– Programmable runup/rundown
from 0 to 650 s
– Fast current limitation (FCL) for
trouble-free operation
– Fast, reproducible response of the
digital inputs
– Precise setpoint indication owing to
high-resolution 10-bit analog input
– 4 skip frequencies
– Onboard kWh meter
– 15 test frequencies
Highlights
■ Broad range of different sizes
