Hitachi America Ltd., Industrial Systems Division: Regenerative Converter Units

The RCU Series of regenerative converter units offers an affordable green alternative to traditional dynamic braking (DB) systems, says the company. Instead of wasting regenerative energy as heat, the unit reclaims that energy, converting it into three-phase ac power. The energy is recycled through the ac line, resulting in increased energy efficiency and reduced energy consumption. According to the manufacturer, incorporating the unit in the HVAC system allows for a smaller cooling system to be applied, offsetting the upfront cost of the regenerative unit and reducing the demands placed on the cooling system. It is simple to install and operate, with only five connections necessary for basic operation.
