Heatsinks for Sevcon Gen4 Controllers

Our line of heatsinks are made in the USA from high-quality extruded aluminum. Choose your size based on which Sevcon Gen4 controller you need to cool.

The dimensions are as follows:

Sevcon Gen4 Size 2 Controller 
Width: 7.280"
Length: 7.5"

Sevcon Gen4 Size 4 Controller
Width: 7.280"
Length: 9" Sevcon

Gen4 Size 6 Controller
Width: 7.280"
Length: 12"

Gen4 DC Controller:
Width: 5.375"
Length: 9"

Each of these sizes share the following characteristics:
Fin Height: 1"
Base: .300"
C/W/3": approximately 1.30 *
Weight per Inch: .37

*These approximate °C/W/3" values are based on natural convection: 70 C temp rise above ambient, based on a single 1" (25.4mm) square heat source centered on the heat sink. If you have distributed loads, then you can expect about a 10% better performance in natural convection and 20% better performance in forced convection. We STRONGLY recommend customers perform their own thermal testing in relation to your specific project.
