Product overview
3.1
Operational area
Frequency inverter designed for a stepless control of fans without additional (electromagnetic) motor
noise.
By using the integrated all-pole effective Sine
fi
lter (phase to phase and phase to ground), an absolute
parallel control of fans without risk of damage for motors is possible. Screened motor cables not
required!
Only suitable for drives with low set-off torque (e.g.: fans or pumps).
3.2
Functional description
The frequency inverters of these series generate their 3~ output with variable voltage and frequency
from the three-phase mains on the input.
The devices are constructed in accordance with the general requirement in EN 61800-2 for adjustable
speed electrical power systems and is intended for one-quadrantdrives.
