SAFTRONICS of Fort Myers, Fla., and the ABB GROUP of Stockholm have created a strategic market alliance to launch the new line of compact DC drives. The DC400 is a three-phase digital drive designed for stand-alone applications, made by ABB, and sold by Saftronics.
Much of the current DC drive market is in need of retrofit products. Typically, the user needs to replace old equipment, where the motor is still good but maintenance on the controls can exceed the cost of a new replacement. For this reason, Saftronics is looking to replace old DC drives with more advanced, feature-rich and cost-effective retrofit packages.
"That's exactly what the new DC400 RetroPak provides," says Don Blickle, Saftronics' DC drives sales manager. "With it we are able to offer customers an application-configured retrofit package that allows them to simply pull out their old drive and plug in the new one, without disruption to their business. Plus, we offer them important application assistance as well as support after the sale."
A major consideration in DC drive replacement is size. With the smallest footprint in the industry, the compact DC400 line is likely to replace older drives without any panel space problems. The DC400's compact size also brings substantial savings to machine builders, allowing them to integrate more components within the same space. This design integrates an IGBT (insulated gate bipolar transistor) field exciter (including fuses and choke). This eliminates the need for a field voltage transformer to match the line supply voltage with that of the motor. The transistorized field supply ensures smooth field voltage, better commutation and increased brush life of the motor.
The new DC400 series includes drives rated up to 500 hp, and is designed for use on line supply voltages from 230 to 500 volts.
