The QS150/15 is a miniature voltage stabiliser.The striking voltage is 170 and for burning currents of 2 - 10 mA the regulation is 5 Volts. The electrode at pin 4 is the priming anode and it should draw no more than 500 μA.![](../pics/abh0133a.jpg)
The bright anode with no view of the other electrodes.The thin glass tube envelope is 18 mm in diameter and, excluding the B7G base pins, is 47 mm tall.References: Data-sheet. Type QS150/15 was first introduced in 1954. See also 1954 adverts. |
