Surplus Boards Inc is an industrial leader in AC and DC drive repairs. We are an independently owned company and operate from southern California.

Over the last ten years we have gained an excellent reputation not only for the reliability and speed of our repairs, but also for our low prices on used, refurbished, and new drives and boards.

Our engineers collectively have over 30 years experience in the industrial AC and DC drive repair business.

Many of the refurbished boards and drives we offer are purchased from users that are replacing or retrofitting their machinery with new state of the art drives. Their used drives are collected, cleaned, and repaired if necessary. We then are able to offer these electronic boards back to the public at a fraction of the cost. In some cases, the drives and boards we offer are obsolete and no longer available as from the manufacturer.

All remanufactured items have been thoroughly cleaned, rebuilt, and tested for functionality before shipment to the customer. We warranty all our inventory for six months.

If you purchase a remanufactured unit and you have a repairable identical unit, we can provide an exchange at a discounted price.
