Power Options
Power options are add on devices that can be used to help increase power factor, improve harmonics, and dissipate regenerative energy.
Name
Purpose
• Improves the drive input power factor.
DC Bus Reactor
• Prevents damage to the drive when the power supply capacity is large. Only use this option when the
power supply capacity is more than 600 kVA.
• Decreases harmonic current
• Improves the power supply total power factor.
• Improves the drive input power factor.
AC Reactor
3% Braking Resistor
10% Braking Resistor Unit
Braking Unit
R1000
Single Phase Converter
• Prevents damage to the drive when the power supply capacity is large. Only use this option when the
power supply capacity is more than 600 kVA.
• Decreases harmonic current
• Improves the power supply total power factor.
Decreases the regenerative energy of the motor and decrease the deceleration time (Duty cycle of 3%
ED). An installation attachment is required.
Decreases the regenerative energy of the motor and decrease the deceleration time (Duty cycle of 10%
ED). The unit contains a thermal overload relay.
Use with a braking resistor unit to decrease motor deceleration times.
The R1000 regenerative module is used to divert energy generated by the motor back onto the line for
use by other loads. The energy is directed back onto the line by taking DC voltage from the drive running
the motor and converting it into a three-phase AC voltage waveform.
The Single Phase Converter is used in single-phase to three-phase conversion applications to eliminate
drive derating. The Single Phase Converter significantly reduces stresses on the power grid with near
unity power factor and less than 10% iTHD.
