About the DS3820

The DS3820 is a Mark IV component that functions as a heat sink.  This unit, which was originally created by General Electric as part of their Speedtronic Mark IV system, is no longer available through the OEM.  However, it can be purchased from AX Control.  Our company works hard to maintain an on-hand inventory of Speedtronic components (Mark I through Mark VI) so we can quickly fulfill your order needs. 

The DS3820 functions as a heat sink.  Heat sink components are used to increase heat flow away from hot devices to maintain their optimal temperature.  They work by increasing the working surface area, which increases heat dissipation as air moves through or across the heat sink.  Heat transfer away from components helps them maintain their proper operating capacities through thermal maintenance.   This is only one heat sink used within the Mark IV system; please be sure to order the correct components for your particular use. 

The Mark IV turbine control system was originally introduced as a replacement for earlier (MK I and MK II) control systems in 1984.   Mark IV systems were specifically designed for gas turbine applications and were the first of the Speedtronic systems to offer triple modular redundant (three individual processors voting on outputs) control.  This type of control system significantly improved uptime in most applications. 

For additional information about the DS3820 heat sink, please refer to original documentation about this part.  Manuals or user guides for the Mark IV system will also be helpful.  AX Control can help you with sourcing these documents if you no longer have your originals that should have been provided with your OEM purchase.
