Product Description

DS200ITXDG1A IGBT Snubber Board MK V General Electric 

The  DS200ITXDG1A is a board component that was fabricated by GE to be used within the Speedtronic Mark V system.  The MKV is one of GE’s later-developed Speedtronic systems for managing gas and steam turbines.   It includes fault-tolerant TMR architecture with two-out-of-three voting on critical controls and protection parameters.  The MKV has the ability to be set up in Simplex form for less complex systems, and still offers fault-tolerant control through software settings with this design.  MKV boards can be purchased from AX Control as reconditioned, fully tested units. 

The DS200ITXDG1A is a small board that functions as an IGBT Snubber Board.  Snubbers are designed as energy absorbing circuits that can suppress voltage spikes that occur when a switch opens.  The switch may be electrical or mechanical.   This is an auxiliary board that connects to a larger motherboard. 

The DS200ITXDG1A is designed with drill holes at each corner and with small indents along its edges.  The board has several heatsinks to allow quick dissipation of built-up heat.  It is populated by several stab-on connectors, by ceramic capacitors, diodes, vertical pin header connectors, and by eight Wima FKP 1 polypropylene capacitors.  These capacitors are designed for high pulse duty and are self-healing.  They have a very low dissipation factor and a negative capacitance change vs. temperature.  These components are placed on the board in two lines of four on opposite sides of the board.
