RBC High Dissipation Resistance Decade 5 Watts per coil

The RBC Series is a robust range of high dissipation resistance decades available in 4, 5 or 6 decade versions and suitable for applications where reasonably precise and stable adjustable loads are required.

Constructed using the same high quality components as our other resistance decades and housed in a light alloy ventilated case, the RBC Series will withstand the most arduous use and give many years service. All parts are fully serviceable and can be repaired in our workshop should the more enthusiastic user damage the units with high overloads.
