HSK160

Heatsink Enclosures These extruded aluminium channels are designed to be used as robust, low impedance, electronics enclosures, but can also be used as free-standing heatsink. Three different extrusions are available, providing a range of sizes and styles. The standard heatsink (HSK) is designed to form an 83mm high enclosure capable of housing a 100VA toroidal transformer. A similar low profile heatsink (LHSK) forms an enclosure 56mm high. The rugged single channel heatsink (RHSK), which is 83mm high, will accommodate a 160VA toroid. Standard Heatsink Enclosure (HSK) A free-standing or 3U rack mount enclosure is achieved by combining two interlocking channels with end panels. Eurocard circuit boards can slide into internal card guides enabling power devices to be attached to the heatsink section of the vertical wall with an M3 screw and half nut. There is no need for drilling. Two boards can be mounted within the enclosure, and a standard spacer can be used to support heavy components. Low thermal impedance heatsink Suitable as heat sink enclosure or as 3U rack plug in unit Accepts Eurocard boards (100 x 160mm or 100 x 220mm) Simple fitting of power devices (M3 x 7 screw and half nut) Enclosure gives RFI protection Accommodates toroidal transformer rated up to 100VA Internal & external M4 nut T slots Other lengths available (Subject to minimum quantity) HSK Specification Extrusion: HE9TF aluminium. Black anodised. Standard Length 160 or 220mm Normal wall thickness 2mm thickness adjacent to power devices 7mm End Panels: HE9TF aluminium.

Eurocard circuit boards can slide into internal card guides enabling power devices to be attached to the heatsink section of the vertical wall with an M3 screw and half nut. PCB s can be mounted vertically or horizontally within the enclosure, and a spacer can be used to support heavy components. Low thermal impedance heatsink Suitable as heat sink enclosure or as 3U rack plug in unit Accepts Eurocard boards (100 x 160mm) or narrower pcb s Simple fitting of power devices (M3 x 7 screw and half nut) Enclosure gives RFI protection External M4 nut T slots Other lengths available (Subject to minimum quantity) LHSK Specification Extrusion: HE9TF aluminium.

A circuit board can slide into internal card guides enabling power devices to be attached using pre-tapped holes in the heatsink. One board can be mounted within the enclosure, and spacers can be fitted between board and floor to support heavy components. Very rugged low thermal impedance heatsink or heat sink enclosure Simple fitting of power devices to heatsink floor Enclosure gives RFI protection External slots in top of section (e.g., to hold instruction booklet) Other lengths available (Subject to minimum quantity) RHSK Specification Extrusion: HE9TF aluminium.
