Operation with increased rated power
Under the application conditions described here the controller can be operated in continuous
operation with a motor of higher performance. The overload capacity is reduced to 120 %.
·
Typical applications:
– Pumps with quadratic load characteristic
– Fan
·
Operation is only permissible
– in the mains voltage ranges mentioned
– at a switching frequency of 2 or 4 kHz
– with the prescribed fuses and cable cross−sections
