About the 0-57210-30

The 0-57210-30 is a Reliance Electric made Circuit Card. There is a distinct possibility that this card was also in production through ABB and Baldor Reliance depending on production years.

The 0-57210-30 was produced to be a part of the Reliance DC2 V*S Controller System. This board is considered to be a replacement part. It is a Regulator Board. All of the regulator circuitry for the system is contained on this particular board. This board can be paired with a lot of the more basic controllers like the DC2-40U, DC2-60U, DC2-70U and DC2-93U controllers.

The 0-57210-30 is 1-2HP 50/60 Hz single-phase regulator board. It has an input of 115/230 VAC and 12.5amps. It has an output of 90/100 VDC and 10A. It has a DC field rating of 50/100VDC at 2A and a short circuit rating of 10kA. This is a single card that does not come with any type of enclosure or chassis. It is mounted onto a raised platform that promotes airflow to the circuity. The user will be able to see and locate the various potentiometers, terminal strips, selector jumpers, and pins. There is also a power cube located on this board that can also be replaced if needed. Inside of this power cube, there are power conversion components like thyristors and diodes.

The 0-57210-30 uses the Reliance instruction manual D2-3231. Before installing this regulator board, please read this manual closely. Be sure to inspect any and all wiring and card components before installing this card. This card should only be installed in a controller enclosure that is in temperatures between 0-40 degrees Celsius.
