SWR OUT<br />
Outputs "PWR OUT" and "SWR OUT", give a DC voltage which should best be elaborated at length<br />
to optimize the reading of an analog instrument to 100µA.<br />
We recommend that you use only and only 50 Ω cable Teflon for connections "IN - OUT because the<br />
energy involved is substantial (@ 1 kW).<br />
Use of adequate support for fixing screws in the holes prepared, but 2.5.<br />
Le Uscite “ PWR OUT “ e “SWR OUT”, danno una tensione continua che và opportunamente<br />
elaborata alfine di ottimizzare la lettura su uno strumento analogico da 100µA.<br />
Si consiglia di usare solo e unicamente cavo 50 Ω in teflon per le connessioni “ IN – OUT in quanto<br />
l’energia in gioco è notevole ( @ 1 KW ).<br />
Usare per il fissaggio su adeguato supporto viti 2.5 ma nelle forature predisposte.
