APSS-1B

Loss-of-Signal Switch

APSS-1B

  • Automatic RF switching on loss of signal
  • Manual override capability
  • Virtually transparent from 5 to 600 MHz
  • Monitors one signal or all signals online
  • Latching and non-latching models

Don’t let loss of signal interrupt your service.

The Trilithic APSS-1B is a rack-mounted SPDT RF switch that is ideally suited for RF LAN fiber communications links, CATV systems and other applications where the continuity of service must be maintained.

The APSS-1B automatically switches to a backup RF source whenever the level of the primary RF source falls below a user-settable limit. LED's indicate which source is currently selected, and a front panel switch is provided for manual operation.

By adding an optional RF filter, the APSS-1 loss of signal switch can be configured to monitor a single frequency.

Think Ahead.
