/members-area/personalblogs/b/john-wiltrout-s-blog/posts/mechanical-current-regulatorIn the good old days (I remember them well) we didn&#39;t use any of the newfangled highfalutin semi conductors to regulate current. When necessary for short term precision current regulation we used a mechanical current regulator like this one:&amp;nbsp...en-USTelligent Community 12https://community.element14.com/members-area/personalblogs/b/john-wiltrout-s-blog/posts/mechanical-current-regulatorSat, 17 Jun 2017 16:36:33 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:7ba91289-614d-4bdb-8bf7-2cd3d219a946DAB0<p>Great post John.</p><p>&nbsp;</p><p>I also remember the spark gap regulators for some devices.</p><p>&nbsp;</p><p>Love the smell of ozone in the morning.</p><p>&nbsp;</p><p>DAB</p><img src="https://community.element14.com/aggbug?PostID=3202&AppID=315&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/members-area/personalblogs/b/john-wiltrout-s-blog/posts/mechanical-current-regulatorSat, 17 Jun 2017 05:20:41 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:7ba91289-614d-4bdb-8bf7-2cd3d219a946mcb11<p>Pretty much the same type regulator appled to many vehicles to control the alternator or generator output.</p><p>In the sace of generators it usually open circuited the output, while an alternator had the field voltage (and therfore current) controlled.</p><p>&nbsp;</p><p>When we were fitted out Radio Inspectors vehicles we often had the alternator replaced with an electronic one and even swapped the dash regulator (usually 8 volts) for electronic regulator to stop the electrical noise both produced.</p><p>&nbsp;</p><p>Mark</p><img src="https://community.element14.com/aggbug?PostID=3202&AppID=315&AppType=Weblog&ContentType=0" width="1" height="1">
