336V

336V is a voltage label that can appear in several different contexts within electronics and electrical engineering. Most commonly, it refers to a direct-current (DC) link or bus voltage that can arise when mains power is rectified and filtered, or it may simply be a catalog or part-number designation in product labeling. Because the meaning depends on context, the term does not designate a single standardized value by itself.

In power electronics, 336V frequently describes a DC bus voltage that results from rectifying a typical mains supply. For example, in many regions with a nominal 230 V alternating current (AC) input, rectification and smoothing produce a DC bus in the approximate range of 320–340 V, with 336 V being a representative nominal value in some designs. The exact voltage can vary with load, input tolerance, regulator topologies, and filtering, so designers specify a range rather than a single fixed number.

Safety and standards are important considerations at this level of voltage. Voltages around 300–400 V DC require appropriate insulation, creepage and clearance distances, and protective measures to reduce risk of electric shock and arcing. Equipment operating near or at 336 V typically falls under stringent electrical safety requirements.

Beyond electrical engineering, 336V may appear as a model or designation in product names, catalog numbers, or part identifiers, independent of its voltage meaning. In such cases, the number serves descriptive or commercial purposes rather than a technical specification. Context is essential to determine which interpretation applies.
