85A2 (CV449) 85 V nominal. Current range: 1 mA to 10mA (4 V regulation). Preferred current: 6 mA. Strike voltage: 125 V Fill gas: Neon Philips datasheet. Photo: © Andy Cowley, M1EBV, 2005. |
| Note that this and many other late-design gas-discharge voltage regulators have multiple anode and cathode connections. It is intended that the ballasted input and the regulated output are taken from separate pins (typically pin 1 in, pin 5 out), so that the circuit receiving the regulated supply is disconnected (i.e., protected from over-voltage) when the regulator tube is removed. |
