About the 0-52855

0-52855 CVCA

The 0-52855 is a Reliance Electric board component fabricated for use within the company’s various drives. 

The 0-52855 is a rectangular board component with an attached faceplate.  The faceplate component has seven rotary dials mounted into its surface.  It also has two small openings, one that allows access to a potentiometer to adjust volt gain, and a second that fronts a red LED indicator labeled F. Min.    The rotary dials are labeled Current Limit, Current Gain, Volt off, Accelerate, Decelerate, Stabe, and FB Comp.   Each rotary dial fastens to a potentiometer on the circuit board to the rear of the faceplate.  The faceplate and circuit board connect together using screws. 

The 0-52855 has nineteen integrated circuits.  It also has transistors, capacitors, diodes, resistors, and two additional potentiometers.  Resistors tend to be made from metal film, although some carbon composite resistors are used on the board, too.   Capacitors on the board include ceramic disk and polyester vinyl capacitors as well as other types.   There is a grid pattern printed across the board’s surface in place of using reference designators.  The rear edge has an extended portion covered in a conductive material; this functions as a sort of backplane connector for the module. 

Additional information regarding the installation of this board component may be found through Reliance user guides or product manuals.  These publications were provided by Reliance with your original product, but if they are no longer available to you, replacements may be found online via ABB or Baldor-Reliance.  Our team can help with this process when you place your order.
