 REG2000 Series

A traditional drive system used for inertia load work generally performs rapid deceleration, braking and positioning. When its motor is in generator mode it produces large amounts of regenerative energy that must be consumed to maintain a stable DC bus voltage and safe operation.

While it is easy to install and is low cost, it takes up a large amount of space and requires installing additional devices to dissipate the heat. This method provides limited efficiency and wastes the regenerative energy.

Delta’s REG2000 series is capable of collecting and converting your system’s regenerative energy into reusable electricity for the ultimate in energy savings.
