ABB ACH580-01-07A6-4 5Hp 460V Vfd, Drive Only

The ABB ACH580-01-07A6-4 is a 5-horsepower, 460-volt variable frequency drive VFD developed for HVAC applications. A VFD, as opposed to conventional on/off controls, modifies the frequency of the power it receives to control the speed of an electric motor. This makes it possible to precisely regulate how different HVAC components, such as fans, pumps, and compressors, operate. The VFD saves operational expenses and energy usage by running equipment at optimal rates. When there is less demand, a fan powered by a variable frequency drive VFD can run more slowly, using less energy than a constant-speed fan. A more comfortable environment is created by the smoother, quieter operation and lower noise levels made possible by precise motor speed control.
