Remotely energized TERRA multiswitches MSV524, MSV532
- More products
Benefits:The multiswitches are designed for construction of large distribution IF CCTV systems;
- Н lines of the trunk;
- Subscriber’s lines are up to 80 meters long;
- Two gain controllers* for power assistance to satellite TV and a separate controller for terrestial TV;
- The multiswitches are optimized to operate with digital-to-analog signals of terrestrial TV;
- Reception of terrestrial TV programs is possible without a CCTV receiver being turned on;
- Visual display of 18 V power supply availability;
- A possibility of power supply from a peripheral 18 V source: a recommended power supply is SA125A-1913G-S(F)
MSV524 5x24 multiswitch;
MSV532 5x32 multiswitch.
