About the 78155-69R
78155-69R Reliance Electric Gate Stack
The 78155-69R is a Reliance Electric component used in company drives and their auxiliary systems. This component can be purchased from AX Control as a reconditioned used part. We also have it available as a never-used liquidated surplus part. The 78155-69R was distributed by Reliance under company names Reliance Electric, ABB, and Baldor-Reliance.
The 78155-69R is a rectifier stack component. It is made up of two sets of two heat sinks that are bolted together across a central metal carrier. Each circuit board has a small thyristor circuit board mounted to its top horizontal surface. These circuit boards are each populated by diodes, resistors, terminal pins, and a transformer. White and red braided wires connect to the terminal pins using connectors; these wires connect to components mounted within the heat sink stacks, including metal oxide varistors and SCR diodes. Additional components are mounted within the hollow base, including capacitors and power resistors.
