About the 78155-56R
The 78155-56R from Reliance Electric is a Gate Stack component. Components like this one are used in Reliance drives and other auxiliary systems. We typically have this unit on our warehouse shelves as both a reconditioned used unit as well as surplus never-used stock. The 78155-56R Gate Stack is no longer available from Reliance Electric under its own name or under other company names like Asea Brown Boveri, Baldor-Reliance, or ABB.
The 78155-56R is a type of rectifier stack component. It is built from two sets of metal heat sink components bolted together on either side of a central metal vertical carrier. Above these heat sinks are mounted small circuit board components that are each populated with resistors, terminal pins, diodes, and a single transformer. Terminal pins are connected to wires that then connect to SCR diodes located between the heat sinks. Additional components are mounted close by the SCRs.
For specific information regarding handling, installation, and maintenance of the 78155-56R component, please refer to original documentation from Reliance like manuals, data sheets, and user guides. Such documentation would have been provided to you by the OEM with your original purchase.
