Subject: Crowbar Circuit From: Peter Mather (peter@mather.com) Date: Thu Nov 19 - 11:24 AM If anyone is interested I've posted a circuit and veroboard layout for a tested and working crowbar circuit based on the MC3423 chip on the blog for my Wittman Tailwind build. Total parts cost around $5. http://tailwindbuild.blogspot.com/2009/11/15th-november-2009-overvoltage-crowbar.html Click on the pics/diagrams to enlarge The variable resistor allows the crowbar voltage to be set as required and compensates for differences in the internal reference voltage on the MC3423. Best regards Peter
