About the I-23
The I-23 is a ignitron manufactured by Taylor / Richardson. Large mercury-pool ignitron rated at 50 kV and 5000 A peak current for industrial welding, heavy pulsed power, and high-current switching.
Key ratings of the I-23 include tube type Ignitron, peak anode voltage 50 kV, peak current 5000 A, average current 50 A, holding voltage <15 V and coolant Water.
Typical applications are resistance welding control, high-current industrial switching, heavy pulsed power, electric arc furnace control and high-power UPS systems. Notable features: 5000 A peak current, 50 kV hold-off voltage, mercury-pool self-recovering cathode and water-cooled jacket.
Ignitrons are mercury-pool switch tubes able to conduct very high currents, used in capacitor-discharge pulsed power, welding control and crowbar protection circuits.
