ABB ACS550 VFD
The ABB ACS550 VFD combines a sophisticated microprocessor with an advanced IGBT power switching technology to deliver volts per hertz, close looped flux vector and sensor less vector control of alternating current motors. The ABB ACS550 VFD control panel offers numerous benefits making it the most user-friendly panel out of all variable frequency drives in the industry. The extensive library of pre-programmed applcation macros maximizes convenience and minimizes start-up time. The ABB ACS550 VFD can handle the most demanding industrial applications in an efficient, dependable and economic manner.The ABB ACS500 VFD is mainly used in pump, fan, conveyor, and other related constant torque applications. The ABB ACS550 VFD is ideal for those situations where there is a need for simple installation, commissioning and where custom or special engineering is not required.
ABB ACS550 Packaged Systems
The ABB ACS550-CC is is a complete drive with bypass package that includes an ABB ACS550 VFD, a bypass function that allows the motor to be run at full voltage in the event the drive is shut down for service, a main disconnect means and branch circuit short circuit and ground fault protection. Complete, pre-engineered packaged systems reduce time, effort and the cost of installion the ABB ACS550 VFD bypass option. The ACS550 VFD bypass function is configured entirely of standard industrial control components. The ABB ACS550 VFD bypass package includes two electrically interlocked contactors, a motor overload relay, a control power transformer with primary and secondary fusing, and a cover mounted drive-off bypass selector switch. The ABB ACS550 VFD bypass is accomplished by means of the two contactors. One is the bypass contactor used to connect the motor directly to the power line. The second contactor is the output that disconnects the motor from t he drive output when operating in bypass mode. This prevents the back feeding that would occur if line voltage were applied to the drive output terminals. The ABB ACS550 VFD output contactor and the bypass contactor are electrically interlocked to prevent simultaneous operation.
ACS550 Enclosure Options
ABB ACS550 VFD with bypass packages are available in Nema 1 and Nema 12 enclosures through 100 horsepower in power ratings of 208-230 voltage. ABB ACS550 VFD with bypass packages are also available in Nema 1 and Nema 12 through 400 horsepower at 480 voltage and 150 horsepower at 600 voltage. For outdoor applications, Nema 3R enclosures are sheet steel construction with a tough powder coat paint finish for corrosion resistance and include a 100 watt, thermostatically controlled space heater and thermostatic control of the force ventilated cooling system as a standard.
