We build our own transformer and rectifier assemblies. We carry many types of enclosures in stock. Hence it is very easy for us to build a Transformer/Rectifier assembly in a short time. These variable Transformer/ Rectifier assemblies are extremely popular for OEM and field applications where a certain DC output is required, but no “off the shelf” solution seems feasible.
