Motor reactors

5.1.1

Description

Motor reactors reduce discharge currents which means that longer motor cables may be
used.
At the same time, the stress on the motor windings caused by rates of voltage rise (dv/dt) is
also diminished.
Requirements:
• Maximum ambient temperature:
• Pulse frequency:
• Maximum output frequency:
• Maximum current limit:
• Operating modes:
