The Carlo Gavazzi RHS90A is a heatsink assembly specifically engineered for mounting 1x 1-phase solid-state relays (SSR). This assembly provides efficient heat dissipation, crucial for maintaining SSR performance and longevity. It's designed for versatile mounting options, including DIN rail and panel mounting, making it suitable for a wide range of industrial applications. The RHS90A is RoHS compliant, ensuring environmental responsibility. A thermal interface material (HTS02S) is included for optimal heat transfer, although a phase change pad (RKHT) is also available for enhanced performance.
