SpeedStar 519 SWD VSD
The sine wave VSD package is designed to mitigate supply power harmonic current and voltage distortion and to provide clean power to the downstream device. On the basis of standard harmonic guidelines, these VSDs achieve 18-pulse harmonic cancellations by using a patented phase-shifting integral autotransformer. This design is significantly more efficient than a typical low-voltage drive system that uses an external isolation phase-shifting transformer, further reducing operational costs.
SpeedStar 2000 Plus Drive and SpeedStar SWD Sine Wave Drive
The SpeedStar 2000 Plus drive is used typically with surface pumping systems amd the SpeedStar SWD sine wave drive, which has an integral output sine wave filter, is used typically with ESPs. The output voltage wave form is similar to that of a true sine wave and thus results in less voltage stress and a longer life for the motor, cable, and other electrical components.
VariStar 2000 Plus and SWD Drives
This basic variable speed drive package also uses the integral output sine wave filter, typical for controlling and protecting ESPs.
REDAStar Low-Voltage Variable Speed Drive
Specifically designed for and manufactured in Russia, the REDAStar low-voltage variable speed drive (VSD) meets stringent customer specifications as well as national industrial and safety standards, including GOST standards for electrical components.
