About the 0-56951-301
The 0-56951-301 is a Regulator board for the Reliance Electric SP500 AC Drive series. The SP500 drive is a pulse width modulated drive that can be used with either single- or three-phase power. Transients in this system are suppressed by on-board metal oxide varistor suppressors.
The 0-56951-301 functions as a regulator board for the drive system and is designed to govern the open-loop operation of the drive to allow for adjustable-speed performance. The operation of the drive through the regulator can be adjusted through a keypad controlled by a microprocessor on this board. Display data like fault codes or drive parameters are fed to a four-character display, also located on this board.
The 0-56951-301 includes a terminal strip on its surface along one edge. This is used to connect and receive I/O signals. It is recommended that a minimum wire size of 20 AWG is used (max 14 AWG) with a maximum tightening torque of 0.5 Newton-meters.
Other board components include a relay, integrated circuits, LED indicators, transistors, and capacitors. The board also has a single jumper switch that is used as an analog speed reference input. Reliance manuals have detailed information regarding the proper setting of this jumper.
Additional information regarding the handling and installation of the 0-56951-301 can be found using Reliance publications like user guides and manuals. Please read through these documents before unboxing your new part for your own safety.
