Information About 78155-77A
The 78155-77A is a heat sink assembly manufactured by Reliance Electric for use in industrial rectifier stack applications. Its primary role is to collect and dissipate heat generated by power conversion components operating under high electrical loads. The unit features a flat mounting surface with four central mounting holes and an extended section that supports additional electrical components mounted directly to the heat sink. Designed for integration into drive and rectifier systems, it supports thermal stability and long-term component reliability.
Key Features
- Rectifier stack thermal management: Designed specifically to dissipate heat from rectifier stack components used in industrial drive systems.
- Integrated electrical components: Includes a mounted metal oxide varistor and a high-power resistor to support voltage suppression and energy dissipation.
- High-power resistor assembly: Fitted with a 50 W, 30 Ohm resistor (63481-40AX) mounted directly to the heat sink for effective thermal transfer.
- Flat mounting design: Features four central mounting holes to allow secure installation within rectifier and drive assemblies.
- Extended component surface: Side-mounted section provides a dedicated surface for electrical component attachment and heat conduction.
- Industrial-grade construction: Built to withstand continuous operation and elevated temperatures in demanding industrial environments.
- Compatibility with legacy systems: Used in Reliance Electric and ABB-associated rectifier stack designs for drive applications.
The 78155-77A delivers the reliability and precision required for effective heat dissipation and component protection in Reliance Electric industrial rectifier and drive systems.
