Product details
The Sencore VB273 is an intelligent 2:1 redundancy switch that also monitors both satellite signal paths, so switching decisions are based on deep analysis of each signal. It takes two post-modulator inputs and feeds one transmit output, watching every ETSI TR 101 290 parameter and switching only when the other path is clean. Magnetically latched relays hold their state and pass the signal even with power off. It comes as an IF kit (70/140 MHz) or an L-band kit (950-2150 MHz), each with the VB300 1RU chassis, VB120D probe, VB272 demodulator and licenses.
Key features

Frequently asked questions
Does Digisat supply and support Sencore equipment?
Yes. Digisat supplies Sencore receiver decoders, satellite modulators, contribution encoders, chassis and monitoring with quote-based pricing for broadcasters, cable and IPTV operators, government and enterprise buyers, and our engineers can help integrate them with your antennas, LNBs, BUCs and uplink chain.
What happened to Wellav products?
Wellav products are now sold and supported by Sencore. The DMP 900 platform continues under the Sencore name, and older Wellav encoders, IRDs, transcoders and QAM processors are replaced by the DMP 900 or by current Sencore receiver decoders. Digisat can help you choose the right replacement.
Need it installed, aligned or supported?
Digisat engineers install, commission and maintain satellite ground systems for government agencies, teleports and broadcasters worldwide. Request installation or engineering support.
