PowerGard™
18-pulse
Class 8839 Type CPD Series B
Power
quality counts when you have to measure it
Schneider Electric’s experience and expertise in power distribution
and power quality measurement are combined with solid state motor control
to produce the Class 8839 Type CPD PowerGard clean power drives ranging
from 50 to 500HP, 460 VAC. PowerGard drives combine the harmonic mitigation
benefits of patented 18-pulse technology with the proven reliability of
the Altivar® 58 TRX power controller to form the perfect solution.
These clean power (low harmonic content) drives maintain minimal AC line distortion with high true power factor specifically designed to comply with IEEE 519 guidelines at the equipment level. This technology enables PowerGard drives to achieve in excess of 95% cancellation of characteristic harmonic currents. Other multi-pulse topologies vary greatly in design and effective cancellation techniques and do not provide balanced cancellation of harmonic currents.
A
cost-effective approach to harmonic mitigation
To offer a true cost-effective approach
to harmonic mitigation, Schneider Electric combines 18-pulse technology
for a high horsepower offering with the capability to provide a tailored
solution for small horsepower drives through the use of either line reactors
or drive isolation transformers.
Details make a difference
- Uses multiple communication protocols, making it the most connectable drive on the market
- Features
control connections that are pre-wired with pull-apart
control terminals, minimizing the potential for miswiring control
connections - Offers
resettable overcurrent, brand circuit protection and disconnect
means, eliminating the need to stock expensive fuse replacements - Designed
with optimal rated rectifiers for load share, improving
reliability and reducing the need to stock renewable parts - Manufactured with customer specified control strategy and application interface requirements
