 +====== SG94 ======
 +**Power supply SG 94**; developed by [[Autophon|Autophon AG, Solothurn]].
  
 +To power the wireless sets from the [[SE-206|SE206/​209]]-family,​ [[Autophon]] developed a power supply for mobile use, it can be powered from vehicle batteries from 6 V, 12 V and 24 V and provides the necessary voltages for heaters and plate voltages.
 +
 +{{:​images:​se-206-sg94.jpg?​direct&​400|}}
 +
 +The AC voltage is generated by to vibrators, one is powered by 12 / 24 V and the second by 6 V vehicle onboard voltage. There is also the possibility to connect a mains transformer [[NTS94]], for this, you have to select the connector marked with "​~"​.
 +
 +The power supply is activated by means of a relay when the push-to-talk pushbutton of the headset is pressed down.
 +
 +The power supply is also equipped with an AF amplifier and a speaker.
 +
 +===== Technical Data =====
 +  * **Heaters voltage** 1.4 V; plate voltage +180 V for transmitter output stage, +90 V for all other circuits in the transmitter and receiver, + 45 V for plate voltage of V1-V3 is generated over a resistor from the + 90 V voltage; - 45 V to power the relay and for negative grid voltages.

 +
 +Valves: V202 AF preamplifier and V203 AF final stage.\\ ​
 +V205 in the amplifier for the microphone and line out signals.
 +
 +==== Dimensions ====
 +  * 340 x 237 x 131 mm , 14.7 kg
 +
 +==== Use ====
 +The power supply is used to power the [[SE-206|SE-206/​209]] family sets from vehicle onboard power systems and - together with the mains transformer [[NTS94]] - also from AC mains.
