Product overview
3.1
Scope of application
The frequency inverter is designed for a stepless control of fans without additional (electromagnetic)
motor noise.
Only suitable for drives with low set-o
ff
torque (e.g.: fans or pumps).
3.2
Functional description
Frequency inverters of these series generate their 1 ~ output with variable voltage and frequency from
the 1 ~ AC mains network on the input.
The devicesare constructed in accordance with the general requirement in EN 61800-2 for Adjustable
speed electrical power systems and is intended for one-quadrantdrives.
The PFC (Power Factor Controller) makes the output voltage mostly independent of the mains
voltage.
Information
By using the integrated all-pole e
ff
ective 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!
