CBT Partner, Hammond Power Solutions (HPS) has released their Centurion R reactor which provides a unique blend of improved performance and reliability while reducing the product footprint. HPS Centurion R reactors deliver protection for your motors and AC drives while minimizing power system harmonics. They are available in standard ratings from 0.5 HP (373 Watts) to 1000 HP (745 kilowatts), up to 600 V (690 V with de-rating) and are fully compliant with UL, CSA, CE, IEC, and NEMA standards. The efficient and cost effective HPS Centurion R reactors are built to satisfy the power quality needs of demanding AC drive applications.
Why Choose a Reactor?
HPS reactors are designed to address line-side 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, HPS reactors reduce the motor operating temperature and audible noise by moderating line transients seen by the motor. The use of HPS 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.
- Every reactor is vacuum pressure impregnated (VPI) with VT (Vinyl-Toluene) Polyester Resin to minimize audible noise.
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
- Open core & coil or Type 1 standard
- Rugged steel enclosures with UL50 ANSI 61 gray paint
- Enclosure Kids are available separately and can be field installed. The assembly would be US Listed if it’s done in a UL approved location.
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
