CV5 mercury vapour rectifier (4049D, made by STC).
 |
The valve measures approx 240x60mm. |
| Filament voltage | 4V |
| Filament current | 11A |
| Max PIV | 20kV |
| Max peak anode current | 5A |
| Max average anode current | 1.25A |
| Max permissible condensed mercury temperature range | 25 to 50 C |
This valve is designed to be mounted vertically, base downwards. The condensed mercury temperature is the temperature of the coolest part of the bulb. This should be just above the base. Air should be blown at this part of the bulb to keep the condensed mercury temperature within the specified limits.
