A traditional drive system that is used to perform rapid deceleration, braking and positioning is in high inertia load which means its motor is in the generator mode that produces large amounts of regenerative energy. This energy must be consumed to maintain a stable DC bus voltage and safe operation. The traditional method to solve the regenerative energy problem is to install a brake resistor. 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 collects and converts regenerative energy into reusable electricity for the ultimate in energy savings. It is developed for customers that targets on solving the regenerative energy problem. The installation process is as simple as installing a brake resistor, but with only half the size and excellent efficiency. Implementing an REG2000 series to an inverter system optimize the drive’s braking capability and results better drive performance. This eco-friendly solution provides high value-added performance and reusable energy to sustain a green environment.
