OmniPulse DC Drive

DC Drives

Kor-Pak specializes in retrofitting older DC cranes and outfitting them with new technology with the objective of making them safe, efficient, and reliable.  DC Drives can provide an ideal alternative to older and sometimes obsolete DCCP systems.  DC Drives allow complete motor control and eliminate wear and excess energy consumption which results in cost savings and less downtime

  • OmniPulse™ DDC Digital DC Drive
  • OmniPulse™ DSD DC Control

We invite you to look at the DDC. Presentation for End-users to obtain a better understanding of the concepts behind the DDC Drive as well as the features and benefits that make them superior to DCCP (Direct Current Constant Potential) systems.  If you are interested in pursuing DDC technology for your application, please contact  a Kor-Pak representative and the Omnipulse DDC Application Questionnaire will help you get started in gathering preliminary information.
