The Telewave PM10C5S RF Power Monitor Alarm Panel, is a single channel, single antenna automatic alarm panel for low transmit power and high VSWR, featuring "true VSWR" circuitry and a built-in power monitor. The 2RU panel (3.5” x 19”) mounts in any standard rack or inside most base station cabinets, and can be powered directly from 120 VAC or 12 VDC.
Whenever a low transmitter power condition is sensed by the PM1C1S, a latched relay closure occurs and a red light on the front panel turns on. Both normally-open and normally-closed relay contacts are provided.
A high VSWR condition is indicated by a second latched relay and light. These contacts can be used to remotely activate light, speakers, or other alarm systems. The relays and lights are reset by means of a front panel RESET button.
The panel also operates as an inline power monitor, measuring both forward and reverse RF power, with readings displayed on a 3.5-inch meter. A PM-2A power monitor for the appropriate frequency band is included, attached to the rear panel.
The PM1C1S has 2 meter scale options: 0-250 watts, or 0-400 watts. The meter scale and frequency band must be specified with the order.
