Application Notes:
A 3 % Line Reactor will reduce incoming power by 3%. Thus 480 VAC will be reduced
to a nominal 465 VAC.
A 5% Line Reactor will reduce incoming power by 5%. Thus 480 VAC will be reduced
to a nominal 456 VAC.
Use an Output Reactor for motor lead lengths of 50 to 100 feet.
Use a dV/dT Output Filter for motor lead lengths over 125 feet.
For over 750 feet advise of motor lead length and cable size.
Shipping by ground UPS is included.
