Description
The ABB ACH180-04S-17A0-4 Variable Frequency Drive is motor control with a 480 VAC three-phase power, which is designed to vary the speed, torque of the motor in response to demand. It controls the motor operation of equipment like ventilation fans, air movement and pump operations of HVAC systems allowing them to be operated in a controlled and responsive manner. It works by adjusting the voltage and frequency to the motor to suit load conditions. It can be fitted in electrical panels or control enclosures. This saves energy and minimizes the mechanical load, as well as ensures constant operating condition.
