3HP 4.8Amps - 5% Impedance - 480V 60Hz - Delta Nova Reactor DTX04D8BC

Why choose a Reactor?

Delta Transformers reactors are designed to address lineside issues associated with variable frequency drives. They attenuate voltage and current transients that can cause nuisance tripping of a drive. Reactors also minimize harmonic current levels within the drive supply circuit. When used on the output side of IGBT-based, PWM-type AC drives, Delta Transformers reactors reduce the motor operating temperature and audible noise by moderating line transients seen by the motor. The use of Delta’s reactors enhances the overall system performance, life expectancy, and efficiency of the motor.

Construction

Assembly 

• The impedance of the reactors is accurately controlled by maintaining the core gaps in the flux path. 
• In some HP ranges, bobbins are used to provide exceptional mechanical strength and increase the product reliability.
• All reactor are vacuum pressure imprenations.

Terminations

• Finger-proof terminal blocks are provided on rated currents of approximately below 65 Amps.
• Terminal pads are supplied on approximately 65 Amps and above.- Terminal pads are brazed to ensure electrical integrity.

Enclosures 

• Type 1 standard (3R available; consult Delta for availability.
• Rugged steel enclosures with UL50 ANSI 61 grey paint
• Enclosure kits are available separately allowing assembly in approved facility.

Benefits 

• Mitigate nuisance tripping
• Extend the life of switching components and motors
• Reduce audible motor noise and motor operating temperature
• Mitigate the effect of long lead length
• Minimize harmonic distortion
• Reduce line notching
