Ignitron

Description | Ignitrons are ignitor-fired mercury pool rectifiers with very high peak and average current handling capability. Low frequency ignitrons were the backbone of the welder control and electroplating industries for years. These low-cost devices are still in use today in large motor speed controls and many welder panels around the world. Richardson Electronics offers the following Ignitrons and Accessories: Pulse Power Ignitrons National Electronics' high voltage switching ignitrons are used in a wide variety of pulse power applications, such as capacitor discharge, laser switching, magneforming, magnetizing and crowbar circuits. They are used in switching service for currents ranging to 700,000 Amps with voltages ranging to 50 kV. Solid State Replacements Several "Welder" type ignitrons can be replaced with SSRIs (Solid State Replacement Ignitrons) designed to exact specifications and replace a pair of low frequency resistance welder-style ignitrons. Richardson Electronics may be able to offer an SSRI for your application. Ignitron Connectors & Accessories Ignitrons are unique devices and sometimes require ancillary parts for connecting or mounting. We offer ignitor connection leads, water-cooled mounting brackets for our "A" size tubes and thermostats for our resistance welding tubes.
