Standard reactors can be used on GV3000/SE drives with carrier frequency settings up to 8 kHz.
All reactors listed are UL-recognized (UL-506 File #E53094) and CSA certified (CSA File # LR29753).

This example shows how to measure various motor configurations when the maximum motor lead length is 76 m (250 ft). Note that drives using
vector regulation can be connected to only one motor at a time.
