About the 0-51890-5

0-51890-5 DPSF Phase Sequence Circuit board

The 0-51890-5 is a component fabricated by Reliance Electric as part of their various drive systems.  In some cases, boards from Reliance Electric will not carry the company name but rather will be marked as being manufactured by Baldor-Reliance or by Asea Brown Boveri (ABB.)  The part number is the same in all these cases.

The 0-51890-5 includes a front faceplate that attaches to the circuit board by three screws threaded through factory made drill holes.  The silver faceplate is marked with the Reliance logo and with the board number. It has a single light indicator that is marked “phase sequence.” The LED is wired to the board by two wires.

The 0-51890-5 has a printed gird located on the top surface of the circuit board.  One of the grid axes is designated by letters, the other by numbers. The board components are not marked by reference designators.  

The 0-51890-5 only has a few components on the board’s surface.  This includes two types of diodes, resistors, a polyester vinyl capacitor, and several large axial electrolytic capacitors.  The rear edge of the board is drilled in one location. This edge extends into a tab. The tab is covered by conductive material.  

If more information is required about the board, such is specific operation information or information regarding handling or installation, please refer to publications from Reliance such as data sheets, manuals, or user guides.

Our warehouse is located south of Raleigh, North Carolina.  All static-sensitive boards are stored and shipped protected by an anti-static wrap.  If you would like a shipping quote to your location, we are happy to provide this upon request.
