Product Description

The 701819-303AC is a Power Cube Rectifier created by Reliance Electric. This part could have been sold under the names Asea Brown Boveri and Baldor Reliance depending on when it was actually mass-produced.  This Power Rectifier Cube has been retired by Reliance Electric and other manufacturers. AX Control does, however, attempt to keep this item in stock. Please call us directly to discuss the availability and condition of the 701819-303AC.

The 701819-303AC is a Power Cube that is used on ¼ to ¾ hp 115 VAC, ½ to 1-1/2hp 230 VAC, or 2 and 3 hp 230 VAC systems. This is a replacement part for a Reliance Electric MiniPak DC V*S Drive. Typically, you will need two of these per controller.

The 701819-303AC has the ability to provide adjustable DC power to the motor armature circuits. It does this by using single-phase AC power to be phase-controlled rectified. Two of these Power Cubes are needed in the larger Power Module. Each of the cubes contains 2 SCRs. The Power cube has the ability to transfer heat well. It has a small design and is easily replaced. 

 This cube is designed as a metal base under a carrier with eight stab-on connectors on its top. This component is mounted in the controller’s base using a spacer and a screw.

For more information about this Power Cube, please consult Instruction Manual, D-3899-1, which was provided by Reliance Electric.
