PRO-AREL1-12V
Alarm box used for detecting high SWR in antenna systems.
DESCRIPTION
PRO-AREL1-12V is an alarm box used for detecting high SWR in antenna
systems. The PRO-AREL1-12V is connected to a power monitor, e.g.
PRO-PM2-2/70 25W, and this will enable you to adjust the power
monitor so that the PRO-AREL1-12V gives an alarm signal at e.g. SWR
2:1 at a certain frequency/power.
The alarm drives a latched relay and a light-emitting diode and that
mode is active until the reset button is pressed.
It is possible to connect an external alarm such as light, loudspeaker
etc. (max. 1 A, NC or NO on a contact rail).
