Solid State Decoupler (SSD)
BSS Technologies manufactures industrial-grade Solid State Decouplers designed to provide reliable DC blocking and AC continuity, to keep your infrastructure safe from AC interference and surges.
Manufacturing Excellence, Engineered by BSS Technologies
In-House Production & Quality Control
BSS Technologies maintains complete control over the production lifecycle of our Solid State Decouplers. By managing the assembly and rigorous testing process in-house, we ensure that every unit meets the highest standards for performance, durability, and safety.
Custom Configurations & Extreme Durability
Our manufacturing process is designed to ensure maximum reliability, starting with precise quality control where every device is verified for threshold accuracy during production. We provide custom configurations, including tailored DC threshold ranges, to meet your unique site specifications. Furthermore, all our SSD units are built from robust materials, ensuring consistent performance in extreme environmental conditions ranging from -45°C to +65°C.
Provides simultaneous DC decoupling and AC continuity.
Always fails safely into a grounded short state.
Delivers an extremely low impedance path for AC currents.
Decouples electrical equipment from site grounding grids
Actively protects dielectric flange joint insulation
Prevents hazardous voltage build up on pipeline segments.
Instantaneous switching defends critical infrastructure.
Solid State Decoupler Features
Delivers steady operation with a reliable 50A and 100A current capacity.
Safely withstands AC fault levels up to 150 kA for 30 cycles.
Features a robust 100 kA lightning surge protection rating.
Blocks DC with standard -3V to +1V or tailored custom threshold ranges.
