Application Notes
The main range of applications covers timing circuits and circuits for industrial electronics. The GR 46 tube may be connected directly to a rectified 220 V a.c. supply. Starter breakdown delays are prevented by an appropriate gas mixture or use of auxiliary anode for rapid voltage increases.
