The Delta VFD-B series is a general purpose NEMA 1 drive and offers V/F, Sensorless Vector and Closed Loop Vector control. With its Constant Torque rating and 0-2000Hz output, the VFD-B is designed to handle most conventional drive applications found in the industrial manufacturing industry. The VFD-B series drives are used in many applications including: HVAC, Compressor, Crane Gantry, Elevator, Escalator, Material Handling, Water/Wastewater, and Woodworking to name a few.
Delta Bypass Panels play an important role in a system to reduce energy usage,optimize AC motor speed control, extend motor life, and reduce overall cost. The bypass capabilities allow the motor to be operated from either the Delta VFD or at full speed, directly across the line. The Delta Bypass Panel sets a benchmark for cost, performance, quality, and custom engineered bypass panels. Delta offers both the standard bypass panel, or our custom engineered panel to fulfill all your specification requirements.

The ABB ACS550 is an AC inverter drive that controls the speed of AC induction motors by converting a fixed frequency input to a variable frequency. It's suitable for a range of applications, including pumps, fans, conveyors, and mixers. Here are some of its features:
Control panel
The ACS550 has a multilingual, graphic display panel that can be mounted on the drive or remotely. It also has an assistant to help users get started.
Preprogrammed macros
The ACS550 has a library of preprogrammed macros that can be used to configure inputs, outputs, and parameters for specific applications.
Option slots
The ACS550 has two option slots that can be configured with relay outputs and communication bus adapters.
Brake chopper
All R1 and R2 frame size drives have an integral brake chopper.
Energy efficiency
The ACS550 has counters that show saved energy, carbon dioxide emissions, and cost.
Safety
The ACS550 should only be installed by a qualified electrician. Dangerous voltage is present at the power circuit terminals even when the motor is stopped.
The ACS550 has been replaced by the ACS580.

Simple operation
-
Simple cabling
The integrated spring clamps to connect
control and power lines quickly ensure reli-
able and simple cabling.
-
Easy parameterization
With the help of the parameterization soft-
ware FR-Configurator a series of easy func-
tions such as graphical machine analysis to
optimize the drive system are available.
-
Integrated control unit
The integrated Digital Dial gives the user
direct access to all important parameters
much more quickly than would be possible
with normal keys.
In addition to entering and displaying vari-
ous parameters, the integrated four-digit
LED display also monitors and displays cur-
rent operating values

iG5A is designed to easily change the fan in case of a fan breakdown. By controlling the cooling fan, iG5A provides a virtually quiet environment according to the status of operation. The 4-direction key provides easy handling and monitoring.
