Product Overview

HSN Heat sink is a Hanyoung NUX heat sink for thermal management of compatible solid state relays. The range is built around relay compatibility, current capacity and physical size, so the correct heat sink can be selected to suit the associated relay configuration. The available HSN variants include HSN 80, HSN 120, HSN 80-F and HSN 120-F, with additional HSN-80 and HSN-120 model references in the product specifications.

The model details provide direct compatibility guidance. HSN 80 is associated with HSR-2□50□□ at 50(A) and 80 mm, while HSN 120 is associated with HSR-2□70□□ at 70(A) and 120 mm. The fan-equipped variants HSN 80-F and HSN 120-F are associated with HSR-3□50□□ and HSR-3□70□□ respectively, with a 92 x 92 x 25T fan specification. HSN-80 and HSN-120 are also listed with HSR-2 series compatibility and lengths of 80 mm and 120 mm.

Key Features

The HSN Heat sink range provides model-to-relay matching information that is useful during thermal planning for solid state relay assemblies. The most important selection points are the compatible HSR family, operating load current and the available heat-sink or fan arrangement.

The listed variants are:

• HSN 80: HSR-2□50□□ | 50(A) | 80 mm
• HSN 120: HSR-2□70□□ | 70(A) | 120 mm
• HSN 80-F: HSR-3□50□□ | 50(A) | 92 x 92 x 25T
• HSN 120-F: HSR-3□70□□ | 70(A) | 92 x 92 x 25T
• HSN-80: HSR-2☐50☐☐ | 80 mm
• HSN-120: HSR-2☐70☐☐ | 120 mm

Technical Characteristics

The current and dimensional ratings distinguish the available configurations. HSN 80 is specified for 50(A) with a length of 80 mm, while HSN 120 is specified for 70(A) with a length of 120 mm. The fan-equipped HSN 80-F and HSN 120-F configurations are associated with 50(A) and 70(A) operating load current respectively and use a 92 x 92 x 25T fan arrangement.

The additional HSN-80 and HSN-120 references retain the 80 mm and 120 mm length information for HSR-2 series compatibility. These values should be checked against the selected relay and the available installation space before ordering.

Design and Construction

The physical design is centred on the heat-sink length and, for the fan-equipped variants, the 92 x 92 x 25T fan size. This makes the dimensional information particularly important when the relay and heat sink are mounted together inside a panel or enclosure.

The product range therefore provides two main length options, 80 mm and 120 mm, together with fan-assisted configurations. Selecting the exact size helps maintain a practical mechanical arrangement around the compatible solid state relay.

Integration and Operation

Integration of the HSN Heat sink is primarily a compatibility exercise. HSN 80 and HSN 120 are matched to HSR-2 relay families, while HSN 80-F and HSN 120-F are matched to HSR-3 relay families. The applicable operating load current is 50(A) for the 80-size configuration and 70(A) for the 120-size configuration.

For a fan-equipped installation, the 92 x 92 x 25T fan specification should be allowed for in the mechanical layout. The relay model and heat-sink model should be checked together so that the thermal hardware corresponds to the electrical configuration.

Selection and Use

Choose the HSN Heat sink by first identifying the compatible HSR relay family and then confirming the required current and physical size. HSN 80 and HSN 120 provide 80 mm and 120 mm lengths with 50(A) and 70(A) operating load current respectively, while HSN 80-F and HSN 120-F add the fan-equipped arrangement for HSR-3 configurations.

Before installation, compare the exact HSN model, relay compatibility, current rating and available mounting space. HSN-80 and HSN-120 are also listed as compatible with HSR-2 series models. Using the exact matching combination keeps the heat-sink selection aligned with the relay assembly.
